基于BioPerl实现从NCBI中精确下载LEA基因序列

Based on BioPerl Realize Accurately Download LEA Gene Sequences from the NCBI

摘要: 近年来关于抗逆基因的研究，越来越受研究者们的关注，在新疆尤其重视抗干旱基因的研究。基于这些因素，本文根据LEA基因(late embriogenesis abundant gene, LEA)的保守结构域所在片段(下文简称保守结构片段)和相应的关键词，基于BioPerl设计了从NCBI中精确下载LEA基因序列的程序。此程序不仅解决了LEA基因的精确获取，同时也为不同类型序列的精确下载，提供了一种较好的解决办法。

Abstract: Recently, researchers have paid more and more attention to the resistance gene research; in Xinjiang, especially the research of drought resistance gene has attached great importance. Based on these factors, according to the conservative domain structure of LEA gene (late embriogenesis abundant gene, LEA) and the corresponding keywords, this paper designed a program that LEA gene sequences was downloaded accurately from NCBI based on the BioPerl. This procedure not only solves the precise acquisition of LEA gene, but also provides a better solution to download different types of sequence exactly.
