Abstract
We have recently shown that symbiotic nitrogen fixation results in the export of both ammonia and alanine by Rhizobium bacteroids. The ratio between ammonia and alanine is likely to vary as a function of a number of variables. This overturns the long established principal that bacteroids only excrete ammonia and the plant carries out all nitrogen assimilation. Furthermore, we propose that alanine synthesis by bacteroids is part of a homeostatic mechanism to regulate both carbon and nitrogen metabolism in bacteroids. Here we propose to investigate how alanine synthesis and secretion is regulated and measure its impact on plant growth. In addition using 15N2 labelling, we propose to directly measure alanine export in planta.
