| Abstract: | Objective]The full length cDNA sequence of accD gene of acetyl coenzyme A carboxylase （ACCase） 3-CT subunit from Aleurites moluccana tender leaves was cloned to provide references for using this kind of gene and improving the oil content of oil-bearing crops seeds. Method]Degenerate primers were designed based on the conserved region of known accD gene of plants, such as Jatropha curcas and Ricinus communis. Tender leaves of Aleurites moluccana were used as the materials. PCR and RACE technology were used to clone and amplify the full length cDNA sequence of accD gene. Result]We obtained a 1789 bp sequence of full length cDNA of accD gene, which contained 1509 bp open reading frame and could encode 503 amino acids. The accession number of GenBank was KC255250, which was named as amac- cD. The results of BLASTx comparison showed that the homlolgy of the amino acid sequence among accD gene of Aleurites moluccana and the known homologous plants Hevea brasiliensis, Ricinus communis and Jatropha cureas was 90%, 90% and 89%, respectively. Conclusion]The full length sequence of accD gene in Aleurites moluccana had high homology with Hevea brasiliensis, Ricinus communis and Jatropha eurcas. |
