艾克曼棉 斯蒂芬氏棉 陆地棉野生种 基因组 结构变异
2024/4/16
本研究对艾克曼棉、斯蒂芬氏棉和一个陆地棉野生种系进行测序，解析了棉花多倍化及适应性进化过程中广泛存在的基因组结构变异，阐述了棉花生物多样性和棉花驯化的遗传基础；发现编码磷酸肽结合蛋白的基因结构变异可能与棉花纤维长度调控有关，烯酰辅酶Aδ异构酶3和RAP2-7可通过调节植物激素提高棉花非生物胁迫耐受性。研究结果揭示了棉花多倍化过程中的适应性进化机制，为棉花抗性和纤维品质遗传改良提供了宝贵的遗传材料。

A comprehensive identification and function analysis of the ATBS1 Interacting Factors (AIFs) gene family of Gossypium species in fiber development and under multiple stresses
AIFs基因 棉花 纤维发育 非生物胁迫响应
2024/4/16
ATBS1 INTERACTING FACTORs (AIFs)基因是一类bHLH蛋白，在植物生长发育过程中起着重要作用。本研究在亚洲棉、雷蒙德氏棉、陆地棉和海岛棉中分别鉴定得到8, 11, 16和15 AIFs。在该家族基因启动子中发现了多个与生长发育、胁迫和激素相关的启动元件。转录组数据显示该家族基因在棉花的花器官和纤维中高量表达。荧光定量表明该家族基因在纤维起始阶段高量表达。激素处理显示该家...

对16种植物的174个DMP基因的系统发育进行分析，这可分为5个亚家族(I-V)；4个棉种包括58个DMP基因，大部分棉花DMP主要在生殖器官(萼片、花瓣、雌蕊和花药)和次生细胞壁期纤维中表达；基因互作网络表明：DMP作为一种内膜系统参与植物衰老过程和花的生殖发育。本研究对棉花DMP基因家族进行了系统分析，探究了候选基因的潜在功能。
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...
