Multilayered Regulation of Membrane-Bound ONAC054 Is Essential for Abscisic Acid-Induced Leaf Senescence in Rice
), with seven nucleotides inserted between intron 5 and exon 6, truncating ONAC054α protein at a premature stop codon. ONAC054β lacks the TMD and thus localizes to the nucleus. These findings demonstrate that the activity of ONAC054, which is important for ABA-induced leaf senescence in rice, is precisely controlled by multilayered regulatory processes.
