Abstract

Abstract: Abstract: Triacylglycerol (TAG) is the main storage fat of the most oil seeds which is synthesized mainly in the plastid of plant. Diacylglycerolacyltransferase (DGAT) catalyzes the last step of triacylglycerolsynthetic pathway, which is a rate-limiting enzyme of thispathway. In this study, DGAT family genes of soybean are characterized in genome wide. Phylogenetic analysis characterized 3 classes of DGATgenes in soybean, which are belong to DGAT1, DGAT2 and DGAT3, and they distribute in 6 chromosomes of soybean genome.Whole genome expression analysis revealedthat DGAT1 subfamily genes mainly expressed in SAM and green pod while DGAT3 subfamily genes mainly in root, DGAT2 family genes broadly expressedin nodule, leaf, flower and green pod.
