Root Nodule Bacteria: assessing genetic diversity through a systematic biogeographic survey.

root nodules," Trends in Microbiology, vol.
Pulse and grain legumes are grown in the agricultural land in a rotation so as to fix atmospheric nitrogen into the soil because they form nitrogen fixing symbiosomes with soil inhabiting
root nodule bacteria [44].
Chemical fertiliser was then broadcast and
root nodule bacteria were inoculated.
Varietal differences in [N.sub.2]-fixation ability of
root nodules under chilling treatment could also be explained by the anti-oxidative activity of the flavonoids with 3', 4'-dihydroxy configuration.
Whereas bacterial bioluminescence - the principal contribution of the microbial symbiont - is induced in the squid organ within 8 to 10 hours after inoculation (McFall-Ngai and Ruby, 1991), nitrogen fixation by rhizobia does not occur at maximal levels in the
root nodule for days to weeks.
Lectin genes are expressed throughout
root nodule development and during nitrogen-fixation in the Rhizobium-Medicago symbiosis.
bracteata and its associated
root nodule bacteria (Bradyrhizobium sp.).
The current study used the annual legume Amphicarpaea bracteata and its associated
root nodule bacteria (genus Bradyrhizobium) to investigate this issue.
