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