Abstract

Common bean (Phaseolus vulgaris L.) is widely intercropped with maize (Zea mays L.) in the North of Spain. Breeding beans for multiple cropping systems is important for the development of a productive and sustainable agriculture, and is mainly oriented to minimize intercrop competition and to stabilize complementarity with maize. Most agricultural research on intercropping to date has focused on the agronomic and overall yield effects of the different species, but characters related with socio-economic and food quality aspects are also important. The effect of intercropping beans with maize on food seed quality traits was studied for thirty-five bush bean varieties under different environments in Galicia (Northwestern Spain). Parameters determining Asturian (Northern Spain) white bean commercial and culinary quality have also been evaluated in fifteen accessions. There are significant differences between varieties in the selected cropping systems (sole crop, intercrop with field maize and intercrop with sweet maize) for dry and soaked seed weight, coat proportion, crude protein, crude fat and moisture. Different white bean accessions have been chosen according to their culinary quality. Under these environmental conditions it appears that intercropping systems with sweet maize give higher returns than sole cropping system. It is also suggested that the culinary and nutritional quality potential of some white bean accessions could be the base material in a breeding programme the objectives of which are to develop varieties giving seeds with high food quality.

Abstract

Rapid and uniform seed germination and seedling emergence under diverse environmental conditions is a desirable characteristic for crops. Common bean genotypes (Phaseolus vulgaris L.) differ in their low temperature tolerance regarding growth and yield. Cultivars tolerant to low temperature during the germination and emergence stages and carriers of the grain quality standards demanded by consumers are needed for the success of the bean crop. The objectives of this study were (i) to screen the seedling emergence and the phenotypic response of bean germplasm under a range of temperatures in controlled chamber and field conditions to display stress-tolerant genotypes with good agronomic performances and yield potential, and (ii) to compare the emergence of bean seedlings under controlled environment and in open field conditions to assess the efficiency of genebanks standard germination tests for predicting the performance of the seeds in the field. Three trials were conducted with 28 dry bean genotypes in open field and in growth chamber under low, moderate, and warm temperature. Morpho-agronomic data were used to evaluate the phenotypic performance of the different genotypes. Cool temperatures resulted in a reduction of the rate of emergence in the bean genotypes, however, emergence and early growth of bean could be under different genetic control and these processes need further research to be suitably modeled. Nine groups arose from the Principal Component Analysis (PCA) representing variation in emergence time and proportion of emergence in the controlled chamber and in the open field indicating a trend to lower emergence in large and extra-large seeded genotypes. Screening of seedling emergence and phenotypic response of the bean germplasm under a range of temperatures in controlled growth chambers and under field conditions showed several genotypes, as landraces 272, 501, 593, and the cultivar Borlotto, with stress-tolerance at emergence, and high yield potentia

Abstract

Phaseolin is the major seed storage protein of common bean. It comprises a complex set of glycoproteins heterogeneous in their polypeptide composition that is encoded by a gene family. Analyses of phaseolin banding patterns by one-dimensional electrophoresis (SDS-PAGE) have been central to the current understanding of the diversity of wild and cultivated common beans. In this work, we have carried out a detailed description and interpretation of phaseolin diversity in cultivated common beans of different geographic origins (Mesoamerican and Andean gene pools) based on the current two-dimensional electrophoresis (2-DE) technology and mass spectrometry (MS). High-quality 2-DE gel images revealed very complex phaseolin patterns across the studied cultivars. Specifically, patterns of phaseolin within cultivars were organized in a horizontal string of multiple isospot pairs varying in isoelectric point and molecular mass. The degree of similarity among phaseolin patterns was estimated from the percentage of spots shared between pairs of cultivars. Analyses of proteomic distances between phaseolin types by non-metrical multidimensional scaling revealed that 2-DE phaseolin profiles are more similar among cultivars belonging to the same gene pool. However, higher differentiation was found among cultivars of the Andean gene pool. Analysis of genetic variations of the PCR-based SCAR marker of phaseolin seed protein was in general agreement with 2-DE phaseolin patterns, but provided supplementary information regarding diversity among cultivars. Furthermore, the molecular basis responsible for the complexity of 2-DE phaseolin patterns was investigated. Thus, identification of phaseolin spots from 2-DE gels by MALDI-TOF and MALDI-TOF/TOF MS showed that each single isospot pair contained only one type (α or β) of phaseolin polypeptide, but pairs with higher and lower molecular mass corresponded to α- and β-type polypeptides, respectively. In addition, partial and total deglycosylation of seed protein extracts with the enzyme PNGase F indicated that differences between isospots of each pair are exclusively due to a different extent of glycosylation of the sametype of phaseolin polypeptide. Taken together, our observations provide new insights into the study of genetic differentiation of common bean populations based on phaseolin diversity., MICINN, Galician Government, EU-FEDER Funds, The research was supported by AGL2011-25562 and 10PXIB262008PR projects from the Spanish and Galician Governments, respectively, and EU-FEDER Funds.

Abstract

Knowledge of patterns of genetic diversity among existing cultivars helps to broaden the genetic base of new cultivars and maximizes the use of available germplasm resources. This study examined the organization of diversity for morphological traits in 66 landraces of cultivated common bean (Phaseolus vulgaris) from Galicia and its relationship with phaseolin seed protein diversity. Data on growth habit, seed and pod traits obtained from field evaluations at two locations during the 1989-91 cropping seasons were subjected to multivariate statistical analysis. Cluster analysis based on 14 quantitative variables and five qualitative variables identified 11 groups. The land-races were also characterized by phaseolin electrophoresis. The results allowed separation of these landraces into Middle and Andean American groups, which could be further divided into at least eight groups within the Andean American cultivars and three within the Mesoamerican cultivars. These groups in turn corresponded to the previously described races Nueva Granada and Peru of South American origin, and races Durango, Jalisco and Mesoamerica from the Middle American domestication centre. These results confirm the existence of two major groups of germplasm in the cultivated common bean landraces from Galicia, Mesoamerican vs. Andean American. [ABSTRACT FROM AUTHOR]

46. Performance of Common Bean (Phaseolus vulgarisL.) Landraces from Spain in the Atlantic and Mediterranean Environments

Author

Casquero, P. A., Lema, M., Santalla, M., and De Ron, A. M.

Abstract

Ninety-five common bean (Phaseolus vulgarisL.) landraces from Spain were evaluated in three different environments in northern Spain for their agronomic performance and seed quality. Significant differences among landraces were found for 14 quantitative traits related to phenology, yield and its components, and seed quality traits. Environmental effects were significant for all traits evaluated except for seeds pod−1, seed width/thickness, seed weight, and seed water absorption. Landrace by environment interactions were significant for all traits except for seeds pod−1and seed water absorption. Selection of new breeding lines for agronomic performance and seed quality within landraces should be reliable because many of them are mixture of lines. Some heirloom varieties belonging to the types faba, caparrón,riñón,ganxet and tolosana had the best performances regarding to seed quality and yield. Principal component analysis revealed differences among environments affecting the performance of the bean landraces. Variation in the landraces seems to be organized in a different way in each one of the test environments, therefore, low plasticity and specific adaptation of Spanish bean landraces to different environments is derived from this study. Some landraces, especially those large and white seeded should be an useful resource for sustainable farming systems in different biogeographical areas and a worthy germplasm for the genetic improvement of agronomic value and seed quality.

Gonz´lez-Quintela, A., Martínez-Rey, C., Castroagudín, J. F., Rajo-Iglesias, M. C., and Domínguez-Santalla, M. J.

Abstract

Background: The relationship between Streptococcus bovis bacteraemia and gastrointestinal disease (mainly colon cancer) is well known. Patients with advanced liver disease are prone to bacteraemia. Less attention has been paid to the association between liver disease and Streptococcus bovis bacteraemia in the literature. Aims: To evaluate the prevalence of liver disease in patients with S. bovis bacteraemia. Patients and methods: Twenty-two episodes of S. bovis bacteraemia in 20 adults (13 males and seven females, with a median age of 61 years, range 32–94 years) were detected in a single hospital over a 7-year period. Ten of them had endocarditis. Patients' clinical records were reviewed, with special focus on underlying liver and gastrointestinal disease. Results: Eleven patients (55%) had a chronic liver disease. Nine of them were cirrhotics. Ten patients had a history of chronic alcohol abuse, and four patients had hepatitis C virus antibodies (associated with alcohol abuse in three cases). Large bowel disease was present in six out of 13 evaluable patients (adenocarcinoma in three cases). Patients with liver disease were younger than patients without it. Mortality related to S. bovis bacteraemia was particularly high among patients with advanced liver disease (Child-Pugh state C). Bacteraemia recurred two times in one alcoholic cirrhotic, who was diagnosed as having a Dukes-B colon cancer 4.5 years after the first episode of S. bovis bacteraemia. Conclusions: In our area, S. bovis bacteraemia is frequently associated with chronic liver disease. Liver disease may be a predisposing factor for S. bovis bacteraemia.
