Research Abstract |
Leguminous plants fix atmospheric nitrogen gas in symbiotic association with rhizobia. In order to establish a molecular basis for legume and rhizobial symbiotic nitrogen fixation, we studied Fix- mutants of the model legume, Lotus japonicus, and tried to identify the responsible genes and reveal the function of those genes. One of Fix- mutants was shown to be defective in a member of Soluble N-Ethylmaleimide Sensitive Factor Attachment Protein Receptor (SNARE) proteins involved in vesicle trafficking, which is expressed ubiquitously in shoot, roots, and nodules and the transcripts are detected in the vascular tissues.
