To identify the physiological function of Diacylglycerol Acyltransferase 2 (DGAT2) coding gene in the process of tung oil biosynthesis, DGAT2 was cloned from cDNA of tung tree kernel and then linked with pMD18-T vector for sequencing. The 969bp fragment containing Open Reading Frame was acquired. Subsequently, RNAi binary expression vector pD35-DGAT2 was constructed, which expressed DGAT2 in two opposite ways. The studies provide the possibilities to further identify the function of DGAT2 in tung oil biosynthesis by RNAi technology and hold promise for genetic engineering of Venicia fordii.
