The synthesis and accumulation of reserve proteins in seeds require a large supply of reduced nitrogen. Generally, the transport of nitrogen from other parts of the plant involves a few specific compounds, the nature of which depends on the species and growth conditions. The fixation of N 2 by Rhizobium in symbiotic association with soybeans, cultivated in the absence of mineral nitrogen, leads to the incorporation of atmospheric nitrogen in ureides (allantoin and allantoic acid). These compounds form the main nitrogenous components found in the transport stream of nodulated soybeans. On the other hand, soybeans grown in the absence of Rhizobium and with NO3 nitrogen source, contain asparagine as the predominant as transport form of nitroge...
