Abstract Seed viability is an essential feature for genetic resource conservation as well as sustainable crop production. Long-term storage induces seed viability deterioration or seed aging, accompanied by the accumulation of toxic reactive oxygen species (ROS) to suppress seed germination. Controlled deterioration treatment (CDT) is a general approach for mimicking seed aging. The transcription factor ANAC089 was previously reported to modulate seed primary germination. In this study, we evaluated the ability of ANAC089 to control seed viability during aging. Compared with that in the wild-type line, the mutation of ANAC089 significantly increased HO, thereby reducing seed viability after… More >
