Abstract

Bacterial blight resistance gene B5 has received little attention since it was first described in 1950. A near-isogenic line (NIL) of Gossypium hirsutum cotton, Ac B5, was generated in an otherwise bacterial-blight-susceptible ‘Acala 44’ background. The introgressed locus B5 in Ac B5 conferred strong and broad-spectrum resistance to bacterial blight. Segregation patterns of test crosses under Oklahoma field conditions indicated that Ac B5 is likely homozygous for resistance at two loci with partial dominance gene action. In controlled-environment conditions, two of the four copies of B5 were required for effective resistance. Contrary to expectations of gene-for-gene theory, Ac B5 conferred high resistance toward isogenic strains of Xanthomonas citri subsp. malvacearum carrying cloned avirulence genes avrB4, avrb7, avrBIn, avrB101, and avrB102, respectively, and weaker resistance toward the strain carrying cloned avrb6. The hypothesis that each B gene, in the absence of a polygenic complex, triggers sesquiterpenoid phytoalexin production was tested by measurement of cadalene and lacinilene phytoalexins during resistant responses in five NILs carrying different B genes, four other lines carrying multiple resistance genes, as well as susceptible Ac44E. Phytoalexin production was an obvious, but variable, response in all nine resistant lines. Ac B5 accumulated an order of magnitude more of all four phytoalexins than any of the other resistant NILs. Its total levels were comparable to those detected in OK1.2, a highly resistant line that possesses several B genes in a polygenic background.

Abstract

Seedlings of upland cotton (Gossypium hirsutum L.) are vulnerable to the partial or complete loss of their cotyledons due to an array of biotic and abiotic causes. These experiments were conducted in the field over a 4-yr period to determine the effects of such losses in the early vegetative cotyledon growth stage on lint yield, selected lint yield components, and fiber traits. Loss of half a cotyledon apparently stimulated the cotton plant to overcompensate for lint yield by 4 to 6%. Overcompensation was not detected for the lint yield components or fiber traits. The plant compensated for the loss of up to one cotyledon in all traits except fiber strength in one year. Loss of one and one-half cotyledons reduced lint yield (11-33%), picked lint percentage (up to 2.1%), pulled lint percentage (0.4%), micronaire (up to 0.2 units), and fiber elongation (up to 0.3%). Loss of both cotyledons reduced lint yield (81-100%), picked lint percentage (up to 4.6%), pulled lint percentage (4.7%), boll size (0.85 g [boll.sup.-1]), micronaire (up to 1.6 units), and fiber elongation (up to 1.4%). Fiber length and length uniformity were not affected at any level of cotyledon removal. Fiber strength exhibited significant differences among treatments in one experiment, but no trend. The elimination of both cotyledons when the first true leaf was about the size of a dime was considerably less harmful to the plant than when done earlier in the season.

Abstract

The VIRGO experiment for the detection of gravitational waves is a big challenge both for physics and for technology. In particular, to satisfy the stringent requirements on the alignment and position of its suspended optical components to keep the detector at its point, a very complex distributed and supervised control system has been implemented. The current constraints are about [10.sup.-10] m RMS for the longitudinal control ('Locking') and [10.sup.-9] rad RMS for the angular degrees of freedom ('Alignment'). These requirements are satisfied by means of a specially designed hierarchical architecture for the local control system. It is necessary for managing the hard task of filtering all the environmental noises that limit the sensitivity of the interferometer. On the other end, the interferometer is supervised by a distributed global control system to maintain the detector fully operational. In this paper we describe the status of the real-time distributed control system of the Virgo interferometric detector of Gravitational waves, its performances and planned improvements.

Abstract

Virgo is an experiment aiming at the detection of gravitational waves emitted by astrophysical sources. Its detector, based on a 3 km arms interferometer, is a complex setup which requires several digital control loops running up to 10 kHz, an accurate and reliable central timing system and an efficient data acquisition, all of them being distributed over 3 km. We overview here the main hardware and software components developed for the data acquisition system (DAQ) and its current architecture. Then, we briefly discuss its connections with interferometer's controls, especially through the automation of the interferometer's startup procedure. Then, we describe the tools used to monitor the DAQ and the performances we measured with them. Finally, are described also the tools developed for the online detector monitoring, mandatory complement of the DAQ for the commissioning of the Virgo detector.

Abstract

Six family groups of upland cotton (Gossypium hirsutum L.), derived by backcrossing, were compared over multiple environments. Each group consisted of a different nonrecurrent parent (NRP), a cultivar from Africa with resistance to bacterial blight [caused by Xanthomonas campestris pv. malvacearum (Smith) Dye]; the same recurrent parent (RP), 'Westburn 70', susceptible to that disease; the [F.sub.4] of the cross between them; and the [Bc.sub.1][F.sub.4], [Bc.sub.2][F.sub.4], [Bc.sub.3][F.sub.4], and [Bc.sub.4][F.sub.4] generations. All entries were evaluated for lint yield, six fiber properties, and seven agronomic characters. Reactions to three diseases were also determined for the [Bc.sub.4][F.sub.4] and the RP in two environments per disease. The objectives of this study were to measure the degree and rate of recovery of RP traits through four backcross generations in upland cotton as well as to determine reactions to three diseases (including blight) in the [Bc.sub.4][F.sub.4] generation. Eighty-four sets of comparisons (six family groups by 14 traits) were possible in the portions of the study not involving diseases. The NRPs differed significantly from the RP in 69 of the 84. Among those 69 combinations, the number (and percentage) of significant differences from the RP in the F4, [Bc.sub.1][F.sub.4], [Bc.sub.2][F.sub.4], [Bc.sub.3][F.sub.4], and [Bc.sub.4][F.sub.4] were 47 (68%), 35 (51%), 25 (36%), 25 (36%), and 14 (20%), respectively. No significant differences were detected in any family group between the [Bc.sub.4][F.sub.4] and the RP for lint yield, 2.5 and 50% span lengths, uniformity index, and pulled lint percentage. One or more such differences were found for micronaire, [T.sub.0] and [T.sub.1] fiber strengths, picked lint percentage, boll size, bur size, lint weight per boll, lint index, and seed index. Depending on the trait, three, four, and often more backcrosses were required to recover the RP traits. Several instances of transgressive segregation were noted mainly in the earlier backcross generations. The observed rate of recovery of RP traits was 96% of the theoretical rate. The only intentional selection in these materials was for bacterial blight resistance. As expected, the level of blight resistance in the [Bc.sub.4][F.sub.4] reflected that of its NRP. Also as expected, the level of tolerance to Verticillium wilt (caused by Verticillium dahliae Kleb.) and of resistance to the Fusarium wilt [caused by Fusarium oxysporum Schlect. f. sp. vasinfectum (Atk.) Snyd. & Hans.]--root-knot nematode [Meloidogyne incognita (Kofoid & White) Chitwood] complex in the [Bc.sub.4][F.sub.4] reflected that of the RP with three possible exceptions., BACKCROSS BREEDING is a relatively simple, predictable method for improving a cultivar by incorporating one or two, never more than a few, traits into it from another source.

Abstract

Twelve cotton (Gossypium hirsutum L.) cultivars, released by the Oklahoma Agricultural Experiment Station (OAES) between 1918 and 1982 inclusive, were evaluated in multiple environments to estimate selection progress over time for lint yield, six fiber properties, eight agronomic characters, and three diseases. Lint yield increased 1.2 to 3.0 kg [ha.sup.-1] [yr.sup.-1] on dryland and 3.7 to 5.6 kg under irrigation. Five of six experiments indicated that a selection plateau had not yet been reached for lint yield. Increases in fiber length of 0.04 to 0.06 mm [ya.sup.-1] and of 0.02 mm [ya.sup.-1] were observed for 2.5 and 50% span lengths, respectively. Uniformity index and micronaire displayed significant differences among cultivars, but no significant trends over time. [T.sub.0] fiber strength increased by 0.5 kN m [kg.sup.-1] [yr.sup.-1]. Initially, [T.sub.1] fiber strength declined; but since the mid-1940s, its trend was upward by 0.6 kN m [kg.sup.-1] [yr.sup.-1] in a generally linear fashion. Picked and pulled lint percentages increased rapidly at first but reached a plateau in the mid-1940s. Boll size increased over time, and bur size increased slightly. Weight of lint per boll increased through 1955, but has since remained essentially constant. Relatively large improvements were made in lint index through 1964; but since then, the trait has remained stable. Seed index increased by 0.02 g [(100 seed).sub.-1] [yr.sup.-1] on dryland and by 0.03 g under irrigation. Lock tenacity increased by 1.7 g force [yr.sup.-1]. Positive trends over time were also noted for resistance to bacterial blight [caused by Xanthomonas campestris pv. malvacearum (Smith) Dye] and to the Fusarium wilt [caused by Fusarium oxysporum Schlect. f. sp. vasinfectum (Atk.) Snyd. & Hans.]-root-knot nematode [Meloidogyne incognita (Kofoid & White) Chitwood] complex but not for tolerance to Verticillium wilt (caused by Verticillium dahliae Kleb.). The above findings were compared with those in numerous other breeding programs. This information provides a historical perspective on genetic gain for a number of traits among the cotton cultivars released by the OAES., NUMEROUS STUDIES in cotton have described long-term trends in lint yield, fiber properties, and agronomic characters for the cultivars developed over time in selected regions of the Cotton Belt, in [...]

Abstract

Cotton (Gossypium hirsutum L.) cultivars normally have lysigenous glands conditioned by two dominant, independently inherited alleles, Gl(sub 2) and Gl(sub 3). Glandless (gl(sub 2)gl(sub 2)gl(sub 3)gl(sub 3)) isogenic lines are now available for a number of those cultivars. Such lines allow a decisive test for the relationship formerly proposed between accumulation of the herbicide prometryn (N,N prime-bis(1-methylethyl)-6-(methylthio)-1,3,5-triazine-2,4-diamine) in the lysigenous glands and increased crop tolerance to that pesticide. Experiments were conducted in a growth chamber to compare the prometryn tolerance of glanded vs. glandless 'Empire 61 (WR)' and 'Westburn M' isolines. Two intermediately glanded Empire isolines (Gl(sub 2)Gl(sub 2)gl(sub 3)gl(sub 3) and gl(sub 2)gl(sub 2)Gl(sub 3)Gl(sub 3)) were also available for analysis. Ratios derived from leaf chlorophyll fluorescence measurement curves established that the photosynthetic inhibition caused by prometryn in glanded cotton seedlings was of less intensity and shorter duration than in glandless plants within the same genetic background. Comparisons involving the intermediately glanded Empire isolines suggested that Gl(sub 2) enhances seedling tolerance more than does Gl(sub 3). Glanded vs. glandless isolines in five genetic backgrounds (i.e., Empire 61 (WR), Westburn M, 'Delcot 277', 'TH 149', and 'Stoneville 213') plus the two intermediate Empire isolines were also evaluated for prometryn tolerance in the field. Visual crop injury ratings and measured lint yields support the growth chamber data. The treated glanded isoline on each background displayed less injury (20-56%) and higher yield (44-60%) than the corresponding glandless isoline. Again, Gl(sub 2) showed less injury than Gl(sub 3) though differences in lint yield were not significant. Clearly, lysigenous glands enhance prometryn tolerance in cotton, and higher gland density is directly associated with higher photosynthetic rates and reduced crop injury.

Abstract

The objectives of this study were to adapt a screening method previously used to assess seedling drought tolerance in cereals for use in cotton (Gossypium hirsutum L.) and to identify tolerant accessions among a wide range of genotypes. Ninety genotypes were screened in seven growth chamber experiments. Fifteen-day-old seedlings were subjected to four 4-day drought cycles, and plant survival was evaluated after each cycle. Three cycles are probably the minimum required in cotton work. Significant differences (at the 0.05 level or lower) among entries were obtained in four of the seven experiments. A "confirmation test" with entries previously evaluated as "tolerant" (high survival) and "susceptible" (low survival) was run. A number of entries duplicated their earlier performance, but others did not, which indicates the need to reevaluate selections. Germplasms considered tolerant included: `IAC-13-1', `IAC-RM4-SM5', `Minas Sertaneja', `Acala 1517E-1' and `4521'. In general, the technique is simple, though time-consuming, with practical value for screening a large number of genotypes. Results from the screening tests generally agreed with field information. The screening procedure is suitable to select tolerant accessions from among a large number of entries in germplasm collections as a preliminary step in breeding for drought tolerance. This research also demonstrated the need to characterize the internal lack of uniformity in growth chambers to allow for adequate designs of experiments.

Abstract

On the Mediterranean island of Corsica, cohabitation between sympatric domestic pigs and Eurasian wild boar (Sus scrofa) is common and widespread and can facilitate the maintenance and dissemination of several pathogens detrimental for the pig industry or human health. In this study, we monitored a population of free-ranging domestic pigs reared in extensive conditions within a 800-ha property located in Central Corsica which was frequently visited by a sympatric population of wild boar between 2013 and 2015. We used GPS collars to assess evidence of a spatially shared environment. Subsequently, we analysed by PFGE of XbaI-restricted DNA if those populations shared faecal Escherichia coli clones that would indicate contact and compared these results with those collected in a distant (separated by at least 50 km) population of wild boar used as control. Results showed that one of eight wild boars sampled in the study area shed E. coli XbaI clones identical to clones isolated from domestic pig sounders from the farm, while wild boar populations sampled in distant parts of the study area shared no identical clone with the domestic pigs monitored. Interestingly, within the sampled pigs, two identical clones were found in 2013 and in 2015, indicating a long-time persisting colonization type. Although the method of isolation of E. coli and PFGE typing of the isolates requires intensive laboratory work, it is applicable under field conditions to monitor potential infectious contacts. It also provides evidence of exchange of microorganisms between sympatric domestic pigs and wild boar populations.

Abstract

Near-isogenic lines of upland cotton (Gossypium hirsutum) carrying single, race-specific genes B4, BIn, and b7 for resistance to bacterial blight were used to develop a pyramid of lines with all possible combinations of two and three genes to learn whether the pyramid could achieve broad and high resistance approaching that of L. A. Brinkerhoff's exceptional line Im216. Isogenic strains of Xanthomonas axonopodis pv. malvacearum carrying single avirulence (avr) genes were used to identify plants carrying specific resistance (B) genes. Under field conditions in north-central Oklahoma, pyramid lines exhibited broader resistance to individual races and, consequently, higher resistance to a race mixture. It was predicted that lines carrying two or three B genes would also exhibit higher resistance to race 1, which possesses many avr genes. Although some enhancements were observed, they did not approach the level of resistance of Im216. In a growth chamber, bacterial populations attained by race 1 in and on leaves of the pyramid lines decreased significantly with increasing number of B genes in only one of four experiments. The older lines, Im216 and AcHR, exhibited considerably lower bacterial populations than any of the one-, two-, or three-B-gene lines. A spreading collapse of spray-inoculated AcBIn and AcBInb7 leaves appears to be a defense response (conditioned by BIn) that is out of control.

Abstract

We have calculated by either macrospin analytical method or micromagnetic numerical solving the microwave-assisted switching of a small rectangular platelet as a function of the amplitude and the frequency of a microwave excitation field. The spectral analysis of this phenomenon reveals that microwave-assisted switching is optimal for a rf slightly lower than the linear magnetic resonance frequency measured at low level. Similar experimental results, obtained on 100 μm scale NiFe structures, reveal the same tendency. Switching time for such a process was obtained from calculations that show that subnanosecond switching times require combinations of large dc and rf magnetic fields. [ABSTRACT FROM AUTHOR]

22. Complexes of gastrin with In3+, Ru3+ or Ga3+ ions are not recognised by the cholecystokinin 2 receptor

Abstract

The peptide hormone gastrin (Gamide) binds trivalent metal ions, including indium (In), ruthenium (Ru) and gallium (Ga), with high affinity. Complexes of gastrin with chelated isotopes of In and Ga have previously been used for the location of tumours expressing the cholecystokinin 2 receptor (CCK2R). The aim of the present study was to purify the complexes of Gamide with radioactive isotopes of In, Ru or Ga and to investigate their ability to bind to the CCK2R. The radioactive Gamide complexes were purified on Sep-Pak C18 cartridges or by anion exchange HPLC. Binding to the CCK2R was assessed with a stably transfected clone of the gastric carcinoma cell line AGS. The 106Ru-Gamide complex could be eluted from the C18 cartridge; the 111In-Gamide and 68Ga-Gamide complexes bound irreversibly. All three complexes were successfully purified by anion exchange HPLC. The failure to detect binding of the 111In-Gamide, 106Ru-Gamide and 68Ga-Gamide complexes to the CCK2R suggests that formation of these complexes will not be useful for the detection of tumours expressing this receptor, but may instead provide alternative ways to block the actions of Gamide as a growth factor or a stimulant of gastric acid secretion. The complexes between the hormone gastrin and radioactive 111In, 106Ru or 68Ga ions were purified by anion exchange HPLC using a NaCl gradient. The failure to detect binding of the complexes to the cholecystokinin 2 receptor suggests that metal ion treatment may provide novel approaches to block the biological actions of gastrin.

Abstract

Seedlings of upland cotton (Gossypium hirsutum L.) are vulnerable to the partial or complete loss of their cotyledons due to an array of biotic and abiotic causes. These experiments were conducted in the field over a 4-yr period to determine the effects of such losses in the early vegetative cotyledon growth stage on lint yield, selected lint yield components, and fiber traits. Loss of half a cotyledon apparently stimulated the cotton plant to overcompensate for lint yield by 4 to 6%. Overcompensation was not detected for the lint yield components or fiber traits. The plant compensated for the loss of up to one cotyledon in all traits except fiber strength in one year. Loss of one and one-half cotyledons reduced lint yield (11-33%), picked lint percentage (up to 2.1%), pulled lint percentage (0.4%), micronaire (up to 0.2 units), and fiber elongation (up to 0.3%). Loss of both cotyledons reduced lint yield (81-100%), picked lint percentage (up to 4.6%), pulled lint percentage (4.7%), boll size (0.85 g boll -1 ), micronaire (up to 1.6 units), and fiber elongation (up to 1.4%). Fiber length and length uniformity were not affected at any level of cotyledon removal. Fiber strength exhibited significant differences among treatments in one experiment, but no trend. The elimination of both cotyledons when the first true leaf was about the size of a dime was considerably less harmful to the plant than when done earlier in the season.

Abstract

Six family groups of upland cotton (Gossypium hirsutum L.), derived by backcrossing, were compared over multiple environments. Each group consisted of a different nonrecurrent parent (NRP), a cultivar from Africa with resistance to bacterial blight [caused by Xanthomonas campestris pv. malvacearum (Smith) Dye]; the same recurrent parent (RP), 'Westburn 70', susceptible to that disease; the F 4 of the cross between them; and the Bc 1 F 4 , Bc 2 F 4 , Bc 3 F 4 , and Bc 4 F 4 generations. All entries were evaluated for lint yield, six fiber properties, and seven agronomic characters. Reactions to three diseases were also determined for the Bc 4 F 4 and the RP in two environments per disease. The objectives of this study were to measure the degree and rate of recovery of RP traits through four backcross generations in upland cotton as well as to determine reactions to three diseases (including blight) in the Bc,F4 generation. Eighty-four sets of comparisons (six family groups by 14 traits) were possible in the portions of the study not involving diseases. The NRPs differed significantly from the RP in 69 of the 84. Among those 69 combinations, the number (and percentage) of significant differences from the RP in the F 4 , Bc 1 F 4 , Bc 2 F 4 , Bc 3 F 4 , and Bc 4 F 4 were 47 (68%), 35 (51%), 25 (36%), 25 (36%), and 14 (20%), respectively. No significant differences were detected in any family group between the Bc 4 F 4 and the RP for lint yield, 2.5 and 50% span lengths, uniformity index, and pulled lint percentage. One or more such differences were found for micronaire, To and T 1 fiber strengths, picked lint percentage, boll size, bur size, lint weight per boll, lint index, and seed index. Depending on the trait, three, four, and often more backcrosses were required to recover the RP traits. Several instances of transgressive segregation were noted mainly in the earlier backcross generations. The observed rate of recovery of RP traits was 96% of the theoretical rate. The only intentional selection in these materials was for bacterial blight resistance. As expected, the level of blight resistance in the Bc 4 F 4 reflected that of its NRP. Also as expected, the level of tolerance to Verticillium wilt (caused by Verticillium dahliae Kleb.) and of resistance to the Fusarium wilt [caused by Fusarium oxysporum Schlect. f. sp. vasinfectum (Atk.) Snyd. & Hans.]-root-knot nematode [Meloidogyne incognita (Kofoid & White) Chitwood] complex in the Bc 4 F 4 reflected that of the RP with three possible exceptions.

Abstract

Twelve cotton (Gossypium hirsutum L.) cultivars, released by the Oklahoma Agricultural Experiment Station (OAES) between 1918 and 1982 inclusive, were evaluated in multiple environments to estimate selection progress over time for lint yield, six fiber properties, eight agronomic characters, and three diseases. Lint yield increased 1.2 to 3.0 kg ha -1 yr -1 on dryland and 3.7 to 5.6 kg under irrigation. Five of six experiments indicated that a selection plateau had not yet been reached for lint yield. Increases in fiber length of 0.04 to 0.06 mm yr -1 and of 0.02 mm yr -1 were observed for 2.5 and 50% span lengths, respectively. Uniformity index and micronaire displayed significant differences among cultivars, but no significant trends over time. To fiber strength increased by 0.5 kN m kg -1 yr -1 . Initially, T 1 fiber strength declined; but since the mid-1940s, its trend was upward by 0.6 kN m kg -1 yr -1 in a generally linear fashion. Picked and pulled lint percentages increased rapidly at first but reached a plateau in the mid-1940s. Boll size increased over time, and bur size increased slightly. Weight of lint per boll increased through 1955, but has since remained essentially constant Relatively large improvements were made in lint index through 1964; but since then, the trait has remained stable. Seed index increased by 0.02 g (100 seed) -1 yr -1 on dryland and by 0.03 g under irrigation. Lock tenacity increased by 1.7 g force yr -1 . Positive trends over time were also noted for resistance to bacterial blight [caused by Xanthomonas campestris pv. malvacearum (Smith) Dye] and to the Fusarium wilt [caused by Fusarium oxysporum Schlect. f. sp. vasinfectum (Atk.) Snyd. & Hans.]-root-knot nematode [Meloidogyne incognita (Kofoid & White) Chitwood] complex but not for tolerance to Verticillium wilt (caused by Verticillium dahliae Kleb.). The above findings were compared with those in numerous other breeding programs. This information provides a historical perspective on genetic gain for a number of traits among the cotton cultivars released by the OAES.

Abstract

Field experiments were conducted in 1996 and 1997 to evaluate the effects of six johnsongrass densities on picker- vs. stripper-harvest efficiency, fiber properties, loan rate, and lint yield loss of cotton. The weed densities employed were 0 (the check), 3, 4, 5, 8, and 15 plants/15 m of row. With three or fewer weeds in 1996 and four or fewer in 1997, harvest efficiencies were 4.9 to 7.6% higher for stripper- than for picker-harvested cotton. At four and higher weed densities in 1996 and at five and higher in 1997, differences in harvest efficiency between the two machines were not significant. For each weed per 15 m of row, stripper-harvest efficiency in 1996 and 1997 was reduced 0.3 and 0.6%, respectively; picker-harvest efficiency was not affected by the johnsongrass densities included herein. Fiber fineness (i.e., micronaire) was significantly reduced at densities of 8 weeds/15 m of row in 1997 and at 15 weeds in both years. A questionable increase in staple length was detected at the 3-weed density...

Abstract

Three experiments were conducted in the field using common cocklebur as a test species to identify weed growth differences due to propagation method and weed age when transplanted (with no crop and with soybean). Two experiments involved weed establishment in noncrop areas using four propagation methods (direct seeded–transplanted, peat tablets, peat pots, and plastic inserts) in a factorial arrangement with three transplant timings (at the cotyledon stage, at two true leaves, and at four true leaves). A direct-seeded method was also included as a check. Propagation methods and transplant timings were contrasted to the direct-seeded method because it was the “most natural” method of those tested. Based on results from the first year, the peat tablet method at the three transplant timings plus the direct-seeded method were used to establish the weed in a field experiment with soybean. In 1996 at 4 wk after emergence (WAE), 8 WAE, and senescence, weeds planted in peat tablets and transplanted at t...

Abstract

The commissioning phase of the Virgo gravity-wave interferometric detector started in September 2003, and is still progressing towards the objective to achieve a stable operation of the detector, at its design strain sensitivity. In October 2004 the interferometer was locked for the rst time in the recycled conguration, with the laser power reduced by a factor of 10. In April 2006, after some important modications of the input optics, the commissioning was able to continue with the full beam power restored. This new phase was also characterized by a strong boost to the noise hunting activity. From September 2006, at the time of this conference, monthly science run were planned to test the detector performance and reliability, and to prepare the transition to the long scientic data taking period which is foreseen for 2007 in coincidence with LIGO. In this article the main features of Virgo, together with its actual status and the plans for its future upgrade, are presented.

Abstract

Four field experiments were conducted to measure the effects of sevenIpomoea hederacea(L.) Jacq. densities onGossypium hirsutumL. lint yield, stripper-harvest efficiency, and fiber properties. The seven densities were 0, 2, 4, 6, 8, 10, and 12 weeds 10 m−1of row. Data were used to develop prediction models to compare with those previously constructed that used fewer experiments and fewer weed densities in this range.Gossypium hirsutumlint yield in kilograms per hectare and as a percentage of the weed-free control best fit a linear regression model.Gossypium hirsutumlint yield reductions for each increase of one weed 10 m−1of row ranged from 30.7 to 36.2 kg ha−1at Chickasha and from 35.4 to 36.4 kg ha−1at Perkins. Lint yield reductions for each weed 10 m−1of row ranged from 3.8 to 6.9% at Chickasha and from 3.9 to 6.0% at Perkins. All plots could be mechanically stripper harvested, except for the 12-weed density at Chickasha in 1994 and the 10- and 12-weed densities at Perkins in 1996. Harvest efficiencies were not significantly different in any experiment. The only fiber properties to display significant differences were micronaire and strength at Chickasha in 1994. Prediction models calculated herein were highly similar to those previously constructed.

Abstract

Four field experiments were conducted in Oklahoma to measure full-season Palmer amaranth interference on cotton lint yield and fiber properties. Density of the weed ranged from 0 to 12 plants 10 m−1of row. Cotton lint yield vs. weed density fit a linear model for densities ⩽ 8 weeds row−1at Perkins and Chickasha in 1996 and at Alms in 1997. At Perkins in 1997, all densities fit a linear model. For each increase of 1 weed row−1, lint yield reductions were 62 kg ha−1(or 10.7%) and 58 kg ha−1(or 11.5%) at Perkins and at Chickasha in 1996, respectively. At Perkins and Alms in 1997, for each 1 weed row−1, lint yield was reduced 71 kg ha−1(or 5.9%) and 112 kg ha−1(or 8.7%), respectively. Lint yield vs. end-of-season weed volume fit a linear model except at Alms in 1997. For each increase of 1 m3of weed plot−1, cotton lint yield in 1996 was reduced by 1.6 and 1.5% at Perkins and Chickasha, respectively. In 1997 at Perkins and Altus (⩽ 6 weeds), each increase of 1 m3of weed plot−1reduced lint yield 1.6 and 2.3%, respectively. Lint yield vs. end-of-season weed biomass fit a linear model in all four experiments. Lint yield was reduced 5.2 to 9.3% for each increase of 1 kg of weed biomass plot−1. Fiber analyses revealed significant differences for micronaire (fiber fineness) among weed densities in two experiments, marginal significance in a third, and none in a fourth. An intermediate number of weeds often resulted in improved fiber micronaires in these environments. No other fiber properties were influenced by weed density.

Abstract

The objectives of this study were to adapt a screening method previously used to assess seedling drought tolerance in cereals for use in cotton (Gossypium hirsutum L.) and to identify tolerant accessions among a wide range of genotypes. Ninety genotypes were screened in seven growth chamber experiments. Fifteen-day-old seedlings were subjected to four 4-day drought cycles, and plant survival was evaluated after each cycle. Three cycles are probably the minimum required in cotton work. Significant differences (at the 0.05 level or lower) among entries were obtained in four of the seven experiments. A "confirmation test" with entries previously evaluated as "tolerant" (high survival) and "susceptible" (low survival) was run. A number of entries duplicated their earlier performance, but others did not, which indicates the need to reevaluate selections. Germplasms considered tolerant included: `IAC-13-1', `IAC-RM4-SM5', `Minas Sertaneja', `Acala 1517E-1' and `4521'. In general, the technique is simple, though time-consuming, with practical value for screening a large number of genotypes. Results from the screening tests generally agreed with field information. The screening procedure is suitable to select tolerant accessions from among a large number of entries in germplasm collections as a preliminary step in breeding for drought tolerance. This research also demonstrated the need to characterize the internal lack of uniformity in growth chambers to allow for adequate designs of experiments. Os objetivos desta pesquisa foram adaptar para o algodoeiro (Gossypium hirsutum L.) técnica de seleção previamente usada para avaliar tolerância à seca em plântulas de cereais e identificar acessos tolerantes entre uma gama de germoplasmas. Noventa diferentes genótipos foram avaliados em sete experimentos em câmara de crescimento. Plântulas de 15 dias de idade foram submetidas a ciclos de estresse hídrico de 4 dias e os índices de sobrevivência foram avaliados para cada ciclo. Três ciclos são o mínimo para se trabalhar com algodoeiro. Diferenças significativas (P < 0,05%) entre acessos foram obtidas em quatro dos sete experimentos. Um teste de confirmação foi executado, composto de entradas previamente classificadas como "tolerantes" (alta sobrevivência) e "suscetíveis" (baixa sobrevivência). Um número de entradas duplicou seu desempenho anterior mas outras não, o que indicou a necessidade de reavaliar as seleções. Em geral, a técnica é simples, embora exigente em tempo, e tem valor prático para avaliar grande número de genótipos. Os resultados dos testes avaliatórios geralmente coincidiram com informações subjetivas de campo. Entre outros, os germoplasmas considerados tolerantes foram: `IAC-13-1', `IAC-RM4-SM5', `Minas Sertaneja', `Acala 1517E-1' e `4521'. Esta pesquisa também demonstrou a necessidade de se caracterizar a falta de uniformidade nos ambientes das câmaras de crescimento e assim se escolherem delineamentos experimentais adequados. O procedimento de seleção descrito é adequado para selecionar entradas tolerantes dentre grande número de acessos em coleções de germoplasma e como passo preliminar em programas de melhoramento para tolerância à seca.

39. Increased gastrin gene expression provides a physiological advantage to mice under hypoxic conditions

Abstract

Hypoxia, or a low concentration of O2, is encountered in humans undertaking activities such as mountain climbing and scuba diving and is important pathophysiologically as a limiting factor in tumor growth. Although data on the interplay between hypoxia and gastrins are limited, gastrin expression is upregulated by hypoxia in gastrointestinal cancer cell lines, and gastrins counterbalance hypoxia by stimulating angiogenesis in vitro and in vivo. The aim of this study was to determine if higher concentrations of the gastrin precursor progastrin are protective against hypoxia in vivo. hGAS mice, which overexpress progastrin in the liver, and mice of the corresponding wild-type FVB/N strain were exposed to normoxia or hypoxia. Iron status was assessed by measurement of serum iron parameters, real-time PCR for mRNAs encoding critical iron regulatory proteins, and Perls' stain and atomic absorption spectrometry for tissue iron concentrations. FVB/N mice lost weight at a faster rate and had higher sickness scores than hGAS mice exposed to hypoxia. Serum iron levels were lower in hGAS than FVB/N mice and decreased further when the animals were exposed to hypoxia. The concentration of iron in the liver was strikingly lower in hGAS than FVB/N mice. We conclude that increased circulating concentrations of progastrin provide a physiological advantage against systemic hypoxia in mice, possibly by increasing the availability of iron stores. This is the first report of an association between progastrin overexpression, hypoxia, and iron homeostasis.

Abstract

Summary: On the Mediterranean island of Corsica, cohabitation between sympatric domestic pigs and Eurasian wild boar (Sus scrofa) is common and widespread and can facilitate the maintenance and dissemination of several pathogens detrimental for the pig industry or human health. In this study, we monitored a population of free‐ranging domestic pigs reared in extensive conditions within a 800‐ha property located in Central Corsica which was frequently visited by a sympatric population of wild boar between 2013 and 2015. We used GPS collars to assess evidence of a spatially shared environment. Subsequently, we analysed by PFGE of XbaI‐restricted DNA if those populations shared faecal Escherichia coli clones that would indicate contact and compared these results with those collected in a distant (separated by at least 50 km) population of wild boar used as control. Results showed that one of eight wild boars sampled in the study area shed E. coli XbaI clones identical to clones isolated from domestic pig sounders from the farm, while wild boar populations sampled in distant parts of the study area shared no identical clone with the domestic pigs monitored. Interestingly, within the sampled pigs, two identical clones were found in 2013 and in 2015, indicating a long‐time persisting colonization type. Although the method of isolation of E. coli and PFGE typing of the isolates requires intensive laboratory work, it is applicable under field conditions to monitor potential infectious contacts. It also provides evidence of exchange of microorganisms between sympatric domestic pigs and wild boar populations. [ABSTRACT FROM AUTHOR]

Abstract

Full-season interference and critical duration of early-season ivyleaf morningglory interference with cotton were measured in experiments at two Oklahoma locations. Densities ranging from 0 to 64 weeds/10 m of row were evaluated for their effects on cotton lint yield, fiber quality, and harvest efficiency. Analyses using linear-linear regression proved superior to linear, curvilinear, and linear-plateau models. Lint yield reductions of 36.9 kg/ha (or 5.9%) were recorded at Perkins for each weed/10 m up to 8.7. At densities greater than 8.7/10 m, yield was reduced an additional 3.0 kg/ha (0.5%) for each additional weed. At Chickasha, lint yield was reduced 29.7 kg/ha (or 3.9%) for each weed/10 m up to 9.0 with an additional lint loss of 3.6 kg/ha (0.7%) for each weed above the density of 9.0/10 m. Yield losses were over 80% before fiber length was also reduced. Mechanical harvest was not possible at densities above 8 weeds/10 m at Chickasha and above 16 weeds/10 m at Perkins. In critical duration experiments conducted at Perkins, lint yield was reduced 52.9 kg/ha (or 11.2%) for each week weed removal was delayed up to 9.5 wk. An additional 1.0 kg/ha (0.2%) was lost for each week of interference after 9.5 wk. At Chickasha, lint yield was reduced 49.0 kg/ha (or 7.8%) for each week of interference up to 11.0 wk with an additional loss of 1.2 kg/ha (0.2%) for each week thereafter.

Abstract

Adapting a general crop simulator to a specific locale and validating it present a number of conceptual and practical difficulties. Methods used to adapt the COTTAM simulator for the irrigated cotton ( Gossypium hirsutum L.) planting decision in the Oklahoma Rolling Plains are described as well as an evaluation of the response relationships in the model. COTTAM was adapted by considering how user inputs influence lint yield response as a function of planting date, seeding rate, plant population and cultivar. Those factors were used to define the sources of dynamics and risk in making decisions at planting time. Regression methods were employed to estimate production functions for simulated yield from the adapted model. Technical relationships derived from parameter estimates were used to evaluate output of the adapted model. Relationships estimated from adapted simulator output corresponded to those hypothesized from the literature and estimated from available field data.

Abstract

Les dynamiques hydromorphogéniques au sein des bassins versants de l'Ouest africain constituent des phénomènes complexes que l'étude des processus de sédimentation au niveau des retenues permet d'appréhender et de mesurer. La présente étude met en lumière la faiblesse du comblement de la retenue de Sélingué (Mali), contrairement aux estimations antérieures à la construction du barrage, par constitution d'une nouvelle carte topographique du réservoir. Arrivant en complément des travaux sur la dégradation spécifique des bassins versants et les transports solides, elle permet une nouvelle évaluation de la capacité de stockage de la retenue ainsi que la détermination du rôle de facteurs tels que le couvert végétal ou encore l'occupation humaine dans ces processus.

Abstract

Cotton (Gossypium hirstum L.) cultivars normally have lysigenous glands conditioned by two dominant, independently inherited alleles, Gl 2 and Gl 3 . Glandless (gl 2 gl 2 gl 3 gl 3 ) isogenic lines are now available for a number of those cultivars. Such lines allow a decisive test for the relationship formerly proposed between accumulation of the herbicide prometryn [N,N'-bis(1-methylethyl)-6-(methylthio)-1,3,5-triazine-2,4-diamine] in the lysigenous glands and increased crop tolerance to that pesticide. Experiments were conducted in a growth chamber to compare the prometryn tolerance of glanded vs. glandless «Empire 61 (WR)» and «Westburn M» isolines. Two intermediately glanded Empire isolines (Gl 2 Gl 2 gl 3 gl 3 and gl 2 gl 2 Gl 3 Gl 3 ) were also available for analysis

Abstract

We report on the stabilization of the laser frequency for the Virgo gravitational-wave detector. We have obtained a frequency noise level, measured in loop, of 1.9×10−7 Hz/sqrt(Hz) at 10 Hz for the 1064 nm laser; this value is limited by shot noise. The Allan standard deviation for relative frequency noise is 1.0×10−21 on a 100-ms time scale. The spectral density of the laser frequency noise is negligible in the channel where gravitational waves ought to appear and meets the specifications for the target spectral resolution of the Virgo interferometer in the 10 Hz-10 kHz detection bandwidth.

Abstract

For the LIGO Scientific Collaboration and the Virgo Collaboration; International audience; Gravitational-wave (GW) searches are impaired by the presence of transient sources of noise that can masquerade as a GW signal. This is particularly a burden when these events have larger amplitudes and hence generate an increase in the background for the loudest triggers. Requiring a coincidence between the output of the Virgo and LIGO detectors does not completely eliminate their effect. It is therefore necessary to suppress them in the Virgo GW channel trigger list. Many of these events are due to sources of noise intrinsic to the detector, or environmental disturbances. We here show that many of these sources of noise have been identified, looking at the Virgo GW and auxiliary channels. Data quality vetoes have been defined specifically for the GW burst and inspiral searches, and applied to Virgo data in the joint LIGO/Virgo analyses. Then we show their effect on the analyses performed on the data collected during the first Virgo science run.
