摘要
玉米基因组中大部分是重复序列。重复序列可分为两种类型:一种为串联重复序列,另一种为散在重复序列。串联重复序列主要分布在染色质纽、核仁组织区、着丝粒和端粒区域,还有一些短的串联重复序列随机分布于基因组中。散在重复序列主要是可转移因子,可转移因子分为转座子和返座子两种类型。文中综述了玉米基因组中各种重复序列的研究进展。
The maize genome is made up largely of repetitive sequence which consists of tandem repetitive sequence and dispersed repetitive sequence. Tandem repetitive sequence mainly locates on knob, nucleolar organizer region, centromere and telomere of chromosome. Short tandem repeat randomly distributes in whole genome. Dispersed repetitive sequence is mainly transposable elements which are composed of transposon and retroposon. This paper reviewed progress of repetitive sequence in maize genome.
