水稻全长LTR类逆转座子的鉴定和结构分析

Identification and Structural Analysis of Full-length LTR Class Retrotransposons in Rice

转座子的鉴定和描述是研究水稻基因组生物学功能的一个基础;采用一个较新的逆转座子预测软件LTR_FINDER从水稻品种日本晴372Mb基因组(TIGR Release 5)中鉴定到6,460个全长LTR逆转座子,并根据其内部主要结构域的有无进行了详细分类,共分成29种结构区域类型(SDCs)。

The identification and description of transposons is a basis for studying the biological function of rice genome. This study identifies 6460 full-length retrotransposon LTR from the genome of Nipponbare 372 mb（TIGR release 5） by using a relatively new retrotransposon prediction software LTR_FINDER, classifies it in detail according to the presence or absence of its main domain, and 29 structural region types（SDCs） are classified.
