Cloning of Encoding Squalene Epoxidase Gene and Its Expression in Panax ginseng Root Tissue
摘要
Abstract
Squalene epoxidase mRNA in Panax ginseng root tissue was cloned and its sequence analysis was conducted. Its expression level in ginseng root tissue of different years was detected with relative quantitative fluorescence Real - time PCR. The results showed that complete encoding sequence of SQE in ginseng root was 1 611 bp, which encoded 537 amino acid residues. Bioinformatic analysis of nu-cleotide and amino acid sequence based on SQE genes of squalene epoxidase on GenBank (No.: AB122078.1) showed that the homology was 99.75% and 99.81% respectively. Relative fluorescent quantitative PCR differential expression analysis showed that SQE gene had expression of varying intensities in root tissues of one-year, three-year, four-year and five-year ginseng. SQE genes manifested the highest expression level in root tissues of five-year ginseng.关键词
