origin of abscisicacid. Several apo-carotenoids, putative by-products of abscisicacidbiosynthesis, were synthesised by chemical oxidation but were not detected in plant extracts. In vitro, lipoxygenase cleaved neoxanthin and violaxanthin down to small ( \ C13) fragments. It may be that in vivo any apo-carotenoids formed by the specific cleavage of 9′-cis-neoxanthin, during abscisicacid biosynthesis
