    Journal: Zhongguo Ji Sheng Chong Xue Yu Ji Sheng Chong Bing Za Zhi; 2000; 18(6):339-42. PubMed ID: 12567608.
    Abstract:
    OBJECTIVE: To determine the nucleotide sequence of the 3'-termal of the RESA gene Plasmodium falciparum isolate FCC1/HN, and find out the differences of the sequences of RESA gene among isolate FCC1/HN, FC27, NF7 and Palo Alto. METHODS: 3'-terminal fragment of RESA gene of P. falciparum isolate FCC1/HN was amplified by PCR method, then was cloned into pMD18-T vector. The recombinant was screened and identified by BamHI + XhoI and PCR technique. The nucleotide sequence of the 3'-terminal of the RESA gene was determined by the dideoxy chain termination method. DNASTAR and BLAST software were used to compare and analyze the RESA gene sequences among the different isolates. RESULTS: The 3'-termal fragment of the RESA gene with about 846 bp was specifically amplified by PCR, the recombinant pMD18-T-RESA was successfully constructed. Different degrees of diversity of the RESA gene sequences were found among P. falciparum isolates FCC1/HN, FC27, NF7 and Palo Alto. CONCLUSION: There were differences in the sequences of RESA gene among the P. falciparum isolate FCC1/HN and three other isolates (FC27, NF7 and Palto alto).
