Novel Rhizobium lineages isolated from root nodules of the common bean (Phaseolus vulgaris L.) in Andean and Mesoamerican areas.
The taxonomic affiliations of nineteen root-nodule bacteria isolated from the common bean (Phaseolus vulgaris L.) in Mexico, Ecuador and Brazil were investigated by analyses of 16S rRNA and of four protein-coding housekeeping genes. One strain from Mexico could be assigned to Rhizobium etli and two from Brazil to Rhizobium leucaenae, whereas another from Mexico corresponded to a recently descri...
متن کاملMesoamerican origin of the common bean (Phaseolus vulgaris L.) is revealed by sequence data.
Knowledge about the origins and evolution of crop species represents an important prerequisite for efficient conservation and use of existing plant materials. This study was designed to solve the ongoing debate on the origins of the common bean by investigating the nucleotide diversity at five gene loci of a large sample that represents the entire geographical distribution of the wild forms of ...
متن کاملChromosome 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 کاملGenetic Diversity of Bulgarian Phaseolus vulgaris L. Germplasm Collection
The common bean, Phaseolus vulgaris (L.) Savi, is a member of the genus Phaseolus, belonging to subtribe Phaseolinae. It in turn is a member of the tribe Phaseoleae of the subfamily Papilionoideae and the family Leguminosae (Fabaceae) (van Eseltine, 1931; in Lackey, 1977; Maréchal et al., 1978). The neotropical genus Phaseolus includes about 50 to 60 species of wild bean (Toro et al., 1990), mo...
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...
