Characterization of S40-like proteins and their roles in response to environmental cues and leaf senescence in rice.

Taking all findings together, we concluded that OsS40-1, OsS40-2, OsS40-12 and OsS40-14 genes have potential regulatory function of crosstalk among abiotic, biotic and developmental senescence in rice. Our results provide valuable baseline for functional validation studies of the rice S40 genes in rice leaf senescence.
