摘要/Abstract

摘要： SSRs(Simple sequence repeats)是一类广泛存在于动植物基因组的DNA短串联重复序列,是重要的基因组分子标记。比较不同基因组同源SSR的差异,有利于了解相近物种间的进化过程。文章使用雷蒙德氏棉基因组(D₅)、亚洲棉基因组(A₂)全基因组序列和陆地棉(AD₁)的限制性酶切基因组测序数据,进行全基因组SSR扫描,比较了A组和D组的SSR分布情况,通过识别3个基因组之间的同源SSR,比较它们之间同源SSR重复序列的差异。结果发现,A组和D组同源SSR的分布规律非常相似,但A组与AD组的同源SSR保守性比D组与AD组同源SSR的保守性强。与AD组同源SSR相比,A组中重复序列长度增长的SSR数量约为长度缩短的SSR数量的5倍,在D组中这一比值约为3倍。可以推测,四倍体AD组在与A组、D组的平行进化过程中,由于基因组融合,导致SSR的重复序列长度变化速率与二倍体A、D组有差异,同时这种差异可能导致了AD组SSR重复序列长度在进化过程中与二倍体相比有变短的趋势。文章首次对3个棉花基因组的同源SSR进行了系统地比较,发现了同源SSR在棉属四倍体基因组和二倍体基因组中的显著差异,为进一步揭示棉属基因组的进化规律提供了基础。

Abstract: Simple sequence repeats (SSRs)are a class of repetitive DNA sequences, which are commonly used for genome analysis. Comparison of the homologous SSRs among different genomes is helpful to understand the evolutionary process in relative species. In this study, SSR scanning was performed to investigate their distribution and length variation among the genomes of G. raimondii (D₅), G. arboretum (A₂) and G. hirsutum (AD₁). The results demonstrated that the distribution of SSRs in A genome was very similar with that in D genome, while the length variation of homologous SSRs between A and AD genome was more conserved than that between D and AD genome. Compared with SSRs in AD genome, the number of SSRs with longer motif length in A genome was about five times of those with shorter motif length, while it was about three times in D genome. This implied that the length variation rates of homologous SSRs between diploid cotton and tetraploid cotton were different during the parallel evolution due to the subgenome fusion, and the motif length of most SSRs in tetraoploid genome tended to become shorter than homologous SSRs in diploid genome during the process of evolution. This study comprehensively compared the SSRs in three cotton genomes and revealed the significant difference among them, providing a foundation for further evolutionary study of Gossypium genome.
