This study elucidated the salt tolerance mechanism of Canavalia rosea, a wild relative of adzuki bean known for its exceptional resistance to salinity. The plant exhibits a high capacity to excrete sodium from its roots and forms a barrier that prevents sodium from entering the root system. Additionally, the sodium excretion was found to follow a diurnal rhythm—active during the day and inactive at night. These findings are expected to contribute to the development of salt-tolerant crops and may help address freshwater resource challenges.
