Extensive intraspecific gene order and gene structural variations in upland cotton cultivars
陆地棉 全基因组 比较分析遗传变异
2024/4/16
棉花是重要的工业原材料和天然纤维材料，相比于其他作物，陆地棉的遗传多样性极低，解析其形成原因，对棉花的遗传改良具有重要意义。研究人员通过对两种不同基因型的陆地棉进行全基因组比较分析，发现A08染色体上存在着大片段的遗传变异。该倒位能够将已发表的陆地棉核心种质资源材料分为两类，与利用SNP基因型重构的进化树的分类和主成分分析结果高度一致，表明陆地棉种内可能产生了分化。利用人工创制的群体和陆地棉核心种...
