Chromosome identification in the Andean common bean accession G19833 (Phaseolus vulgaris L., Fabaceae)
Characterization of all chromosomes of the Andean G19833 bean genotype was carried out by fluorescent in situ hybridization. Eleven single-copy genomic sequences, one for each chromosome, two BACs containing subtelomeric and pericentromeric repeats and the 5S and 45S ribosomal DNA (rDNA) were used as probes. Comparison to the Mesoamerican accession BAT93 showed little divergence, except for add...
متن کاملGenotypes of the Common Bean (Phaseolus vulgaris L.) Lacking the Nodule-Enhanced Isoform of Glutamine Synthetase.
Glutamine synthetase (GS) is an octameric enzyme. The nodule cytosol of the common bean (Phaseolus vulgaris L.) has two major types of GS subunit polypeptides ([beta] and [gamma]). As a result, nine different isozymes containing varied proportions of [beta] and [gamma] can be generated. The isozymes are resolvable by native polyacrylamide gel electrophoresis. Staining the gel for GS activity re...
متن کاملMorpho-Physiological Characterization Related to Drought Tolerance of Common Bean (Phaseolus Vulgaris L.) Genotypes
Drought is one of the limiting factor in common bean, development of common bean varieties that adapted to drought situations is the main focus for improving food crops. In this study, 25 genotypes of common beans (Phaseolus vulgaris L.) were grown under drought stress and non-stress conditions. The field work was conducted at Melkassa Agricultural Research Center during the off-season that lai...

متن کاملOn the Origin of the Common Bean (Phaseolus vulgaris L.)
Phylogeographic methods provide the tools to accurately access the geographic origin and diversification of crop species. In the present commentary, I urge the common bean community to face those methods and a tree-thinking mentality with regards to the long standing debate of the origin of common bean. Such efforts will ultimately bring back interest into wild bean studies and reinforce the un...
