The Bradyrhizobium japonicum proline biosynthesis gene proC is essential for symbiosis.

Applied and environmental microbiology - 1 Dec 2000

King N D, Hojnacki D, O'Brian M R

Abstract excerpt

Plant host-derived proline is proposed to serve as an energy source for rhizobia in the rhizosphere and in symbiotic root nodules. The Bradyrhizobium japonicum proC gene was isolated, and a proC mutant strain that behaved as a strict proline auxotroph in culture was constructed. The proC strain elicited undeveloped nodules on soybeans that lacked nitrogen fixation activity and plant hemoglobin. We conclude that...
