Triacylglycerol Biosynthesis in Developing Cotyledons of Safflower (Carthamus tinctorius)

Abstract

Triacylglycerol (TAG) deposition in the maturating seeds of safflower occurs over a narrow but well defined period. This report presents evidence to establish (a) the optimum seed age at which to conduct studies on active TAG biosynthesis (b) the use of such material in in-vivo experiments to examine the current in-vitro based models proposed by Stymne and Stobart (1) for linoleate-TAG formation.
