Nitrogen Fixation and Metabolism in Soybean Plants

Description

In the first part, the authors introduce the progress of researches on nitrogen metabolism of soybean nodules and roots. They investigate the fate of nitrogen fixed in soybean nodules by tracer experiment with 15N2 gas. The results indicate that major part of fixed N in bacteroids (a symbiotic state of rhizobia) is excreted rapidly to cytosol of infected cells in the form of ammonia, then the ammonia is assimilated into amino acids via GS/GOGAT pathway. Then the fixed nitrogen is assimilated into ureides, allantoin and allantoic acid, and then transported to the shoots via xylem. A small portion of fixed N was assimilated in the bacteroids directly into glutamate and alanine. On the other hand, nitrate absorbed from the roots are mainly assimilated into asparagine. The characteristics of nitrate absorption and metabolism were studied. It is well known that nitrate is a potent inhibitor to nodulation and nitrogen fixation, although the inhibitory mechanism is not fully understood.
