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...
Variability in growth and cadmium accumulation capacity among willow hybrids and their parents: implications for yield-based selection of Cd-efficient cultivars（图）
柳树 杂交子代 镉 积累能力
2023/6/2
上个世纪90年代，北美灌木柳育种计划在纽约州启动，经过30多年的杂交、选育以及在美国中、北部的区域试验，选育了一大批高产、高抗的灌木柳栽培品种，目前很多品种在美国已商品化生产。在北美纽约州、宾夕法尼亚州等地，灌木柳被广泛用于工业污染地、垃圾填埋场的植物修复、公路防风雪篱以及生物质能源生产。尽管国际上在柳树重金属污染修复方面做了大量研究，筛选出很多对重金属具有高积累、耐性以及转移的品种，但是重金属积...
