The family Leguminosae is one of the largest families of flowering plants and includes important crop legumes such as soybean (Glycine max) and lentil (Lens culinaris) and forage legumes like alfalfa (Medicago sativa). Legumes vary in habit from annual to perennial and in their genomes from simple diploids to large and complex polyploids. Two legume species,Medicago truncatula and Lotus japonic...

Most species in the Leguminosae (legume family) can fix atmospheric nitrogen (N₂) via symbiotic bacteria (rhizobia) in root nodules. Here, the literature on legume-rhizobia symbioses in field soils was reviewed and genotypically characterised rhizobia related to the taxonomy of the legumes from which they were isolated. The Leguminosae was divided into three sub-families, the Caesalpinioideae, ...

UNLABELLED PREMISE OF THE STUDY Novel markers were developed for pea (Pisum sativum) from pea expressed sequence tags (ESTs) having significant homology to Medicago truncatula gene sequences to investigate genetic diversity, linkage mapping, and cross-species transferability. • METHODS AND RESULTS Seventy-seven EST-derived genic markers were developed through comparative mapping between M....

The genetic structure of populations of the symbiotic nitrogen-fixing soil bacterium Rhizobium meliloti was examined by analysis of electrophoretically demonstrable allelic variation in 14 metabolic, presumably chromosomal, enzyme genes. A total of 232 strains were examined, most of which were isolated from southwest Asia, where there is an unsurpassed number of indigenous host species for R. m...

cultivation of annual medics is a way to increase producing of forage with a better quality, to increase the quantity of producing forage in low yield drylands, and to assisst establishing pasture. this study was conducted in order to investigate the adaptation and determination of quantitative and qualitative characteristics of three species of annual medics. the experimnet was conducted in a ...

The identification of genes under positive selection is a central goal of evolutionary biology. Many legume species, including Phaseolus vulgaris (common bean) and Phaseolus lunatus (lima bean), have important ecological and economic value. In this study, we sequenced and assembled the transcriptome of one Phaseolus species, lima bean. A comparison with the genomes of six other legume species, ...

Small GTP-binding genes play an essential regulatory role in a multitude of cellular processes such as vesicle-mediated intracellular trafficking, signal transduction, cytoskeletal organization, and cell division in plants and animals. Medicago truncatula and Lotus japonicus are important model plants for studying legume-specific biological processes such as nodulation. The publicly available o...
