【Objective】The study was conducted to clarify the microbial community structure in soil with continuous cropping of Curcuma wenyujin and fumigation treatment, aiming to lay a foundation for alleviating continuous cropping obstacles in C. wenyujin cultivation.【Method】The soil under a continuous cropping of C. wenyujin for 3 years was selected and fumigated with dazomet one month before planting C. wenyujin. After 7-month cultivation of C. wenyujin, we collected soil samples from three types of plots: continuous cropping, fumigated and uncultivated. Total soil DNA was extracted, and the population and diversity of microbial communities (fungi and bacteria) were analyzed by using PacBio Sequel thirdgeneration sequencing.【Result】The results showed that C. wenyujin plants in the fumigated soil exhibited good growth and minimal disease incidence, while those in the continuous cropping soil had poor growth and severe seedling death. Analysis of bacterial communities at the phylum level revealed that the abundance of AD3, TK10 and WPS-2 decreased in rhizosphere soil after continuous cropping compared with those in uncultivated soil. Fumigation of continuous cropping soil increased the abundance of beneficial bacteria with biocontrol functions such as Bacillus and Sphingomonas. Among the three soil types, 5 fungal phyla were abundant, including Ascomycota, Basidiomycota, Chytridiomycota, Mortierellomycota, and unclassified_k_ Fungi. Ascomycota had the lowest abundance in uncultivated C. wenyujin soil, but continuous cropping significantly increased its abundance, while Basidiomycota showed a significant decrease. Several beneficial fungal genera, including Chaetomium, Penicillium, Aspergillus, Myrothecium, Thielavia, Humicola, Rhizophlyctis, Microdochium, Ramicandelaber, Albifi mbria, Curvularia, Gigaspora, Nigrospora, Neocosmospora, Talaromyces, Roussoella, Rhytidhysteron, Boothiomyces, Apiotrichum, Ochroconis, Saitozyma, Trichosporon and Phoma, had higher abundance in fumigated soil than that in continuous cropping soil. In contrast, continuous cropping soil had a higher accumulation of pathogenic microorganisms.【Conclusion】Continuous cropping of C. wenyujin leads to the accumulation of harmful soil microorganism, resulting in continuous cropping obstacles. Fumigation with dazomet can reduce the number of soil-borne pathogens and increase the abundance of beneficial microbial populations, thereby mitigating continuous cropping obstacles in C. wenyujin cultivation.

In order to ascertain the fish community structure in the southern waters of the Yangtze River Estuary, 12 stations were set up in the North Port, the North Channel and the South Channel of the Yangtze River Estuary in April （spring） and September （autumn） of 2020, and two voyages of fishery resource surveys were conducted using single bag trawls （minimum mesh size 25 mm）. By calculating individual, weight resource density, relative importance index, α-diversity index, combined with multiple factor regression analysis and canonical correspondence analysis （CCA）, we could determine the spatio-temporal change rule of the community and the impact of environmental factors on the distribution. In this study, 49 species of fish were collected, belonging to 16 orders, 25 families and 41 genera. All of them are warm temperature and warm water fish. The majority of them are estuarine fish, while the narrow salt fish are less and distributed regionally. The resource density in spring is higher than that in autumn, while the weight resource density in autumn is higher than that in spring. Coilia mystus, Coilia nasus, Collichthys lucidus and Miichthys miiuy were dominant species in both seasons. In spring, Miichthys miiuy's individual resource density has the highest contribution rate to the total density and the most significant impact. In autumn, the contribution rate of the individual resource density of Harpadon nehereus is the highest, but the influence of the individual resource density of Coilia nasus is the most significant. The results of individual and weight diversity index showed that H', J' and D' in autumn were higher than those in spring, while the average value of C' in spring was higher. The surface salt temperature of the water surface in the study area is affected by many dynamic factors and there is a large seasonal change. The resource density plane distribution map and the ranking map reveal that certain groups have a life habit of tending to temperature and salt. [ABSTRACT FROM AUTHOR]

[Objective] Study the morphological diversity of Apis cerena cerena in Shaanxi Province, and analyze the relationship between morphological diversity and environment factors, to provide references for the protection of Apis cerena cerena germplasm resources. [Method] Collected 81 populations of Apis cerena cerena in 8 climate types from Shaanxi Province, measured the third and fourth tergum length (T3 + T4), proboscis length (Pro), right wing length (FL), right wing width (FB), right wing area (AW), cubital vein index (Ci) using traditional morphological methods, and calculated the mean and standard deviation of the 6 morphological indicators of Apis cerena cerena under each climate type by SPSS 23.0 software. Use discriminant analysis and systematic clustering to study the morphological diversity of samples, and further analyze correlation between specific indicators and nine environmental factors. These nine environmental factors are 2 geographical factors (longitude, latitude) and 7 climate factors (annual average temperature, annual extreme maximum temperature, annual extreme minimum temperature, annual maximum temperature ≥35 0 °C average number of days, average annual precipitation volume, annual average wind speed and annual average relative humidity). [Result] The results showed that the body size related indexes (T3 + T4, FL, FB, AW) of the bee samples in Yanchuan were the largest; The average values of T3 + T4 and FL of the bee samples in Shiquan were the smallest; The average values of FB and AW of the bee samples in Huanglong were both the smallest; The average values of Pro and Ci of the bee samples in Foping were the largest; The average values of Pro and Ci of the bee samples in Longxian were the smallest. Discriminant and systematic clustering showed that the Apis cerena cerena in 8 climate types can be divided into 4 groups; Longxian, Fengxian and Qianyang were clustered into one group; Foping, Huanglong, Huangling and Zhouzhi were clustered into one group; Yanchuan and Shiquan were singly divided into different groups. Correlation analysis of morphological indicators and environment factors showed, T3 + T4 was positively correlated with latitude, and negatively correlated with annual average temperature, annual extreme minimum temperature, and annual average relative humidity; Pro was positively correlated with average annual precipitation and average annual wind speed; Both FL and AW were negatively correlated with average annual precipitation and annual average wind speed; FB was positively correlated with the annual extreme maximum temperature and the annual maximum temperature ≥35.0 °C average number of days, and negatively correlated with the annual average wind speed, the correlation of the above indicators had reached a significant level. [Conclusion] Climate factors are closely related to the phenotypic plasticity of specific morphological indicators of Apis cerena cerena in Shaanxi. [ABSTRACT FROM AUTHOR]

Objective To study the diversity of the intestinal flora in children with anorexia so as to provide a certain theoretical basis for clinical rational selection of microecological agents. Methods Twenty four children with anorexia in the children healthcare clinic and pediatric clinic of this hospital from May to October 2018 were set as the anorexia group and 25 children undergoing the healthy physical examination were set as the control group. The stool samples were collected for conducting the bioinformatics analysis after PCR and high throughput sequencing. Results In the phylum classification level, there were 14 specieses in the stool samples of the anorexia group and 11 specieses in the stool samples of the healthy children group; in the genus level, there were 193 specieses in the stool samples of the anorexia group and 180 specieses in the stool samples of the healthy children group; in the species level, there were 364 specieses in the stool samples of the anorexia group and 326 specieses in the stool samples of the healthy children group. The dominant bacteria in the phylum level among the detected bacteria in the stool samples of the two groups were the same, which were Firmicutes, Bacteroides, Actinomyces, Proteobacteria and Verrucomicrobia. There were 17 dominant bacteria specieses in the genus level. There was no statistical difference in the composition of Firmicutes, Proteobacteria and Verrucomicrobia between the two groups. The content of Bacteroidetes in stool samples of the anorexia group was greater than that in the healthy control group, and the content of Actinomycete in the anorexia group was smaller than that in the healthy control group. There were statistically significant differences in 13 dominant bacterial genera at the genus classfication level among the detected bacteria in the stool samples between the two groups (P<0.05). The abundance percentage of Bifiobacterium, Blautia, Streptococcus, Erysipelatoclostridium and Eggerthella in the anorexia group was smaller than that in the healthy control group. The abundance percentage of Bacteroides, Faecalibacterium, Subdoligranulum, Alistipes, Ruminococcus 2, Pseudobutyrivibrio, Parabacteroides and Lachnospiraceae_NK4A136_group in the anorexia group was greater than that in the healthy control group. Conclusion The intestinal bacteria of children with non organic anorexia are different from the healthy children. The increases in Bacteroides content and decreases in Bifidobacterium participate in the pathogenesis of anorexia. [ABSTRACT FROM AUTHOR]

[Objective] Diversity of endophytic bacterial separated from the leguminous plants nodules of Wenshan rocky areas was analyzed to provide theoretical references for the legume used in ecological restoration and reconstruction of rocky desertification area.[Method] Using YMA and NA medium, the endophytic bacteria of six legume nodules which were collected from Wenshan esertification region, were isolated and purified. On this basis, restriction enzyme digestion (removing redundant), ARDRA, 16S rDNA sequence homology and biological phenotypic characteristics were analyzed. [Result] The results showed that 135 endophytic bacteria were identified as twenty four species, belonging to seven genera. Among them, 49 strains belonged to Pseudomonas(6 kinds), #7 strains belonged to Pantoea (3 kinds), 25 strains belonged to Enterobacter(6 kinds), 17 strains belonged to Bacillus(5 kinds), 14 strains belonged to Paenibacillus (1 kind), 10 strains belonged to Rhizobium (2 kinds) and 3 strains belonged to Agrobacterium( 1kind). Phenotypic analysis showed that SWFU-W032 strain could grow in the 5% salt medium; 13 endophytic bacteria strains could grow in the pH 12.0 medium, SWFU-W024 and SWFU-W009 strains hydrolyzed starch, SWFU-W011, SWFU-W015 and SWFU-W020 strains synthesized antibiotic; except SWFU-W60, all strains had the ability to produce IAA as well as SWFU-W045, SWFU-W046 and SWFU-W070 strains had the ability to produce protease. [Conclusion] The endophytic bacteria of legume in Wenshan rocky desertification region are quite diversified. Some strains with higher resistance and strong tolerance can promote plant growth and these strains can be used for rocky desertification soil improvement and ecological restoration in rocky desertification areas [ABSTRACT FROM AUTHOR]

In order to reveal the distribution and population characteristics of endophytic fungi from Zanthoxylum nitidum and the antibacterial potential,this study performed molecular identification and analyzed the genetic diversity and antibacterial activity of endophytic fungi from Z. nitidum in Guangxi. Through culture and molecular identification,35 strains,belonging to 15 genera,12 families,10 orders,4 classes,and 2 phyla,were isolated from various tissues of Z. nitidum,of which Colletotrichum and Fusarium were the dominant genera,respectively accounting for 20% of total strains. The diversity of endophytic fungi was significantly different among roots,stems,and leaves,as manifested by the significantly higher Shannon index( H&apos;) in stems( 1. 678) than in roots( 0. 882 1) and leaves( 0. 515 4). The antimicrobial activity analysis showed that 14. 28% of endophytic fungi inhibited at least one indicator pathogen. Among them,Fusarium sp. ZN-34 and Fusarium sp. ZN-26 separately demonstrated the strongest inhibitory effect on Escherichia coli and Staphylococcus aureus. In general,Fusarium sp. ZN-26 and Phialemoniopsis plurioloculosa ZN-35 were advantageous in suppressing the two bacteria owing to the broad spectrum and strong efficacy. In summary,Z. nitidum in Guangxi boasts rich endophytic fungi with the majority showing strong antibacterial activity,which can be used as candidates for the extraction and separation of basic antibacterial substances and the development of natural antibacterial agents.
