Aim: To clone atpA gene fragment from the chloroplast of Dunaliella salina. Methods: According to conserved motif of the homologous amino acid sequence of about ten kinds of algae, we designed a pair of degenerate primers and amplified atpA gene fragment from the chloroplast of Dunaliella salina by PCR technique.The resulting PCR products were inserted into pMD-18 T-vector,and then transformed into E.coli JM109. Positive colonies were selected to determine their sequences. Homologous analysis of the deduced amino acid sequence were performed by BLAST and subsequently compared with GenBank data. Results: The nucleotide sequences were 405 bp which encoded 135 amino acid. The sequence shared high homology with atpA, with identity 92%, 88%, 87%, 86% and 85% to Chlamydomonas reinhardtii, Chlorella vulgaris, Mesostigma viride, Nephroselmis olivacea and Cyanidioschyzon merolae, respectively. Conclusion: It can be concluded that the cloned sequence is atpA gene fragment from the chloroplast of Dunaliella salina.
