摘要: 全长cDNA文库是高效、大规模获得基因全序列信息的一条有效途径,尤其是对基因组庞大,近期内尚不能进行全基因组测序的生物来说,是一条开展功能基因组研究的重要途径。本文对几种全长cDNA文库的构建方法进行了概述,针对各种方法的原理及优缺点做了分析、比较,并结合本实验室的结果,重点介绍了Cap-trapper法在小麦全长cDNA文库中的应用及文库中全长基因比例判定方法。

Abstract: Full-length cDNA library is the cornerstone to find new genes in high-throughput manner, especially in huge genome organisms that cannot carry out whole genome sequencing. In this review, the authors compared the theories and characters of several cDNA construction methods, and introduced Cap-trapper method and standard to judge full-length cDNA in detail according to the utilization of this method in wheat full-length cDNA construction.
