The rice RADIALIS-LIKE3 (OsRL3) connects leaf senescence and salt stress response through ABA pathway

Leaf senescence, the final step of leaf development, is genetically programmed deteriorative process that ultimately leads to the death of annual plants. This process can be triggered by external factors including drought, high salinity stress, ultraviolet light, and pathogen attacks. In plant, abscisic acid (ABA) has substantial function in stress response and regulates various plant developments, including seed germination and dormancy, organ abscission, and leaf senescence.
