The Sym31Gene Responsible for Bacteroid Differentiation Is Involved in Nitrate-Dependent Nodule Formation in Pea Plants

The Sym31Gene Responsible for Bacteroid Differentiation Is Involved in Nitrate-Dependent Nodule... The effects of exogenous nitrate on the number of developing nodules and their leghemoglobin content in the original pea (Pisum sativumL.) line and its symbiotic mutants were studied. Mutation in the Sym31gene conferred the tolerance to nitrate in the corresponding pea line and manifested itself as the number of nodules independent of the nitrate concentration. Thus, the Sym31gene was identified as the only known symbiotic gene involved in both the differentiation of symbiotic compartments and the nitrate-dependent process of nodule formation. The presence of leghemoglobin in double mutants (sym13, sym31) indicates the possibility of the complementary contribution of these genes in the control of leghemoglobin synthesis. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals
