Abstract excerpt

The phytohormone abscisic acid (ABA) plays a central role in regulating key plant processes, including seed germination and drought adaptation. Although our previous work implicated F-box of flowering 2 (FOF2) in ABA-mediated germination and drought responses, its molecular mechanism remained unclear. Here, we demonstrate that plastid-specific ribosomal protein 2 (PSRP2) physically interacts with FOF2 both in...
