| nitrogen-fixing nodules from rose wood legume trees (dalbergia spp.) endemic to madagascar host seven different genera belonging to alpha- and beta-proteobacteria. | although legume biodiversity is concentrated in tropical regions, the majority of studies on legume nodulating bacteria (lnb) are focused on cultivated leguminous plants from temperate regions. however, recent works on tropical regions tend to indicate that the actual diversity of lnb is largely underestimated. in this study, we report the isolation and characterization of 68 nitrogen-fixing root nodule bacteria collected from eight endemic tree species of dalbergia in madagascar. the isolates w ... | 2005 | 16262864 |
