盐穗木HcPS_H基因真核表达载体的构建及转化
Construction and Transformation of Eukaryotic Express Vector of HcPS_ H Gene from Halostachys caspica
摘要
Abstract
[Objective] Halostachys caspica is a leaf - succulent euhalophytic plant capable of surviving under high salinity, and a genus of Chenopodiaceae plants, widely distributed in Xinjiang arid or semi - arid desert saline environments. PS H gene is a part of photosynthetic response to light system gene, which plays an important role in Photosynthesis in plants. [Method] It is helpful to learn the function of HcPS _H in salt tolerance procession of Halostachys caspica by constructing the eukaryotic express system of this gene. We cloned the gene of HcPS _ H from Halostachys caspica by PCR. The target gene fragments and the plasmid pREP -5N were digested with the restriction enzymes SaiI and NotI, and then were linked together by the T4 DNA ligase. Finally, the recombinant eukaryotic expression plasmid HcPS_H-5N was obtained. [Result] The identification results of the individual bacterial colonies PCR, double enzymes digestion and sequencing showed that the recombinant expressing plasmid HcPS _ H - 5N was constructed successfully. [ Conclusion] The recombinant plasmid was transformed into the yeast competent cells by electro - transformation, and the yeast single colonies PCR indicted that the recombinant expressing plasmid HcPS _ H - 5N was successfully transferred.关键词
