摘要：最近，李付广研究员和他的团队进行了一项关于染色体倒位在陆地棉种群分化中作用的研究。值得注意的是，基因组比较鉴定以及随后的RIL种群和种质板单倍型分析证实，大规模倒位在At08染色体上广泛分布，并随着时间的推移介导减数分裂重组的减少，最终导致了陆地棉遗传分离单倍型。这项工作很可能成为棉花功能基因组学研究的新基准，比较分析的科学见解有助于我们了解基因组染色体倒位如何影响减数分裂重组，从而降低植物种群的遗传多样性。



Title: Large-scale inversions majorly drive upland cotton population differentiation
Authors:TIAN Shilin & MA Zhiying 
Abstract
Recently, Li and his team hosted a project on roles of inversion in upland cotton population differentiation. Strikingly, genomic comparison identified, and subsequent RIL population and germplasm panel haplotype analyses confirmed, that large-scale inversions on chromosome At08 are widely distributed and have over time mediated the reduction of meiotic recombination that has ultimately driven genetically isolated haplotypes of G. hirsutum. This work is likely to become the new benchmark for cotton functional genomics research, and the scientific insights from the comparative analyses contributed substantially to our basic understanding of how genomic inversions influence meiotic recombination and thus lower genetic diversity in plant populations.
