Abstract: According to the conserved ammo acid sequences of glycerol- 3- phosphate acyltransferase from several kinds of dicotyls, we designed and synthesized a pair of degenerate primers. RNA was isolated from the highly chilling- resistant rice "Ugeng No.2". A 315bp cDNA fragment was obtained with RT- PCR tech-nique. After purification, the cDNA fragment was cloned into pGEM - T vector directly. The result of identifica-tion by PCR method indicates that the recombinant plasmid pGTL5 contains a 315bp cDNA fragment. The result demonstrated that we had cloned a part of cDNA encoding glycerol - 3 - phosphate acyltransferase. While the cDNA sequence and deduced amino acid sequence reported here was compared with that published abroad, the identity was above 70%. This result hints that the gene is highly conservative on evolution.
