Abscisic aldehyde is an intermediate in the biosynthesis of the plant hormone abscisic acid.[1][2] It is produced by the dehydrodgenation of xanthoxin by xanthtoxin dehydrogenases, which is an NAD+ dependent short-chain dehydrogenas,[3] followed by selective oxidation by abscisic aldehyde oxygenase.[4]
