摘要
根据植物超氧化物歧化酶(superoxide dismutase,SOD)的保守区设计特异性引物,通过RT-PCR技术,克隆杨梅叶超氧化物歧化酶保守区之间的cDNA序列。该序列长233 bp,编码一段由77个氨基酸残基组成的SOD保守区片段,该肽段具有Cu/Zn SOD的特征序列。序列同源性分析表明,该序列与Genbank中已有的其他植物SOD序列的同源性均在86%以上。该基因命名为MrSOD2(Genbank登录号为AB661320)。
A PCR-based homologous cloning strategy was used to identify superoxide disnmtase (SOD) genes from the leaves of Myricu rubra. Results of sequence analysis indicated that a 233 bp cDNA with a conserved regions encoding a 77 amino acids actin ortholog was successfully cloned and characterized. The SOD contained the signature sequence of Cu/Zn-SOD gene family. Multiple alignment analysis of amino acid sequences of the putative SOD conserved regions in Myrica rubra was more than 86% homologous with the best scoring results from similarity searches of sequence databanks. This gene was named as MrSOD2 (Genbank accession No. AB 661320).
