- 摘要:
- 以栽培大豆(Glycine max)吉林35 为材料, 在幼苗期进行干旱、低温处理, 分离mRNA 经逆转录合成cDNA 后, 插入到融合表达载体中, 分别构建了干旱和低温两个融合表达文库。检测表明, 两个初始文库的滴度分别为2 .75×106pfu·mL-1和5.52×105 pfu·mL-1 ;插入的cDNA 片断长度在0.5~ 2.0 kb。此文库的构建为今后分离与干旱、低温相关基因奠定了基础。
- Abstract:
- Two kinds of mRNA were isolated from cultivated soybean variety Jilin 35 pre-treated with drought and low temperatureat seedling stage ,anti-transcripted into cDNA, to construct two relevant fusion expression libraries with insertion ofthese cDNA collection.The primary analy sis showed that the titer of two initial libraries were 2.75×106 pfu·mL-1(drought)and 5.52×105 pfu·mL-1(low temperature).The size of mostly insertion was between 0.5and 2.0 kb.The construction ofthese two libraries will be helpful for the related gene isolation in the future.
