Then the plants carefully uprooted and the root nodules
were surface sterilized by immersion 4 min in a sodium hypochlorite solution (2%) and washed six times with sterile distilled water.

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
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.
