Research Abstract |
Root nodule formation and nitrogen fixation activity was enhanced in enf1 mutant of model leguminous plant Lotus japonicus. In this project, we showed that the number of root nodules was increased by the down-regulation of TRX gene expression. This result indicates that TRX gene is one of a gene that function as an enhancer of symbiotic nitrogen fixation. Soybean mutant line NO. 57 that were isolated by the ABA screening showed enhanced nitrogen fixation activity and also showed higher seed yields.
