Construction and Detection of a cDNA Library of Wheat Seedling Salt Stressed for 72 Hours

摘要/Abstract

摘要:

以98-160盐胁迫72 h叶片的mRNA为起始材料,采用SMART技术构建了一个高质量的cDNA文库,经检测,未扩增文库的滴度为3.44×106pfu/mL,白斑率>85%,插入片段多数在0.5~1.5 kb,有的可以达到2 kb,平均长度为800 bp.因此,按照此方法构建的是1个高质量的cDNA文库,可有效地用于下一步全长基因的筛选和克隆.

Abstract:

A SMART cDNA library was constructed by using the leaves of 98-160 stressed for 72 hours.Quality detection results showed that the titer of the unamplified cDNA library was 3.44×106 pfu/mL(white plague ratio>85%),the insert varied from 0.5 to 1.5 kb with the average of 800 base pairs,some were even larger than 2 kb.Therefore the cDNA library constructed according to the above method was a high-quality cDNA library which could be used for further full-length gene screening and cloning efficiently.
