Identification of the Structure and Origin of Thioacidolysis Marker Compounds for Cinnamyl Alcohol Dehydrogenase Deficiency in Angiosperms

Abstract : Molecular marker compounds, derived from lignin by the thioacidolysis degradative method, for cinnamyl alcohol dehydrogenase (CAD) deficiency in angiosperms have been structurally identified as indene derivatives. They are shown to derive from hydroxycinnamyl aldehydes that have undergone 8-O-4-cross-coupling during lignification. As such, they are valuable markers for ascertaining plant responses to various levels of CAD down-regulation. Their derivation illustrates that hydroxycinnamyl aldehydes incorporate into angiosperm lignins by endwise coupling reactions in much the same way as normal monolignols do, suggesting that the hydroxycinnamyl aldehydes should be considered authentic lignin precursors.
