CAROTENOID METABOLISM AND THE BIOSYNTHESIS OF ABSCISIC ACID

The conversion of all-trans-violaxanthin to 9'-cis-neoxanthin was shown to occur in fluridone-treated etiolated Lycopersicon and Phaseolus seedlings, following exposure to light.The results of deuterium oxide labelling experiments supported this precursor/product relationship, and provided further evidence for the origin of abscisic acid.Several apo-carotenoids, putative by-products of abscisic acid biosynthesis, 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 abscisic acid biosynthesis, are rapidly metabolized by lipoxygenase or similar enzymes.
