摘要: 利用同源克隆和RACE 技术克隆得到能源植物续随子肌动蛋白Actin 基因的cDNA 全长序列,该基因cDNA 全长 1 743 bp (命名为ElActin,GenBank 登录号为KC182753)。序列分析表明,ElActin 开放阅读框长1 134 bp,编码377 个氨基酸,5' 非编码区247 bp,3' 非编码区362 bp。ElActin 与其他植物Actin 基因的核苷酸序列同源性达到82% 以上,氨基酸序列的同源性达 97% 以上。

Abstract: Actins exist widely in plants. In this study, homologous cloning and RACE technology were employed to obtain the Actin fulllength cDNA sequence of Euphorbia lathyris (named ElActin, GenBank accession No. KC182753). Sequence analysis showed that ElActin contained a 1 134 bp open reading frame (ORF) encoding a 377 amino acid residues, a 5'-UTR of 247 bp and a 3'-UTR of 362 bp. Compared with other plants, the homology of nucleotide sequence and amino acid sequence is above 82% and 97%, respectively.
