 note = {Vigna marina is one of wild legumes are distributed at the vicinity of the coast from tropical to sub-tropical regions and have high salt tolerance among terrestrial plants.  For example, Vigna marina can grow at 400 mM NaCl condition. Furthermore, the root nodules on V. marina have a symbiotic relationship with rhizobia that related to the genus Sinorhizobium having high stress tolerance (0.5 M NaCl, 45 ºC, pH 10.5).  To improve symbiotic performance of V. marina with Sinorhizobium under high salt conditions, Sinorhizobium bacterial cells were irradiated by carbon ion-beam at TIARA, QST.  The optimum irradiation dose of carbon ion beam to obtain survival ratio at 0.01% in Sinorhizobium cells was the range from 300 to 400 Gy. So far, we could obtain promising mutants having high NaCl tolerant which can survive at 7.5% NaCl concentration.},
