Molecular characterization of beta- ketoachyl-asp synthase I (Kas I) gene and the effect of abscisic acid (ABA) on oil content , fatty acid composition and the expression of fatty acid synthase genes in chilorella vulgaris (strain UMT-M1)

Abstract

Beta-ketoacyl-ACP synthase I (KAS I) is the fatty acid synthase (FAS) which catalyze the elongation of growing fatty acid chains from butyryl-ACP (C4:0) to palmitoyl-ACP (C16:0). Thus, KAS I play important role as key gene that involved in fatty acid biosynthesis pathway.
