Abstract

In young expanding leaves of Brassica napus, the demand for fatty acids is met by de novo biosynthesis of fatty acid synthase components, as demonstrated by 3-oxoacyl-ACP reductase. Using a novel radio-chemical assay for 3-oxoacyl-ACP reductase and specific antibodies, we have demonstrated a direct relationship between the increase in activity and synthesis of polypeptide. The maximum rate of fatty acid synthesis was between 4 and 7 days post-emergence, but slowed after this point even though 3-oxoacyl-ACP reductase activity was high. Leaf area continued to expand in a linear fashion after reductions in both enzyme activity and the rate of fatty acid synthesis. © 2001 Federation of European Biochemical Societies.
