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...
InDel Marker Based Estimation of Multi-Gene Allele Contribution and Genetic Variations for Grain Size and Weight in Rice (Oryza sativa L.)
Insertion/Deletion (InDel) markers genetic variation multi-gene allele contributions rice (Oryza sativa L.), grain size and weight rice germplasm

Allelic variations at Dhn4 and Dhn7 are associated with frost tolerance in barley
abiotic stress dehydrins gene polymorphism Hordeum vulgare
2014/3/10
The sequences of the closely linked barley dehydrin genes Dhn4 and Dhn7 are both known to vary allelically. Here we associated allelic constitution at Dhn4/7 with frost sensitivity across a panel of 3...
