Gene: Sopen02g030740

General Information

Description Encodes a protein involved in the photoprotection of PSII. An aba4-1 mutant completely lacks neoxanthin,a component of the chromophore of the peripheral antenna system in PSII. ABA4 is required for neoxanthin biosynthesis, an intermediary step in abscisic acid biosynthesis, but no catalytic activity has been detected for the ABA4 protein. | abscisic acid (ABA)-deficient 4 (ABA4) | INVOLVED IN: abscisic acid biosynthetic process, regulation of superoxide anion generation, xanthophyll metabolic process, photoprotection | LOCATED IN: PSII associated light-harvesting complex II, chloroplast envelope | EXPRESSED IN: 23 plant structures | EXPRESSED DURING: 13 growth stages
