Though underlying medical conditions play an important role, many aspects of why COVID-19 severity can differ vastly from one person to another have remained unclear.
物质运输是细胞维持正常生命活动的必需环节。细胞中蛋白质、脂质等大分子的生产、运输依赖由内质网(Endoplasmic reticulum, ER)向高尔基体(Golgi)的物质运输。该过程受阻可造成多种疾病，因而受到广泛关注。近年来，研究发现cTAGE5/MEA6参与ER-Golgi间囊泡运输，并与细胞正常生理功能的维持和多个器官的发育息息相关。

华中地区是粳米的主要产区之一。然而，该地区仍有数十个高产水稻品种质量低下或易感稻瘟病，严重限制了其在水稻生产中的应用。2021年10月5日，Genome Biology 杂志在线发表了来自扬州大学农学院杨泽峰课题组和江苏里下河地区农业科学研究所李爱宏课题组及中国农业科学院植物保护研究所宁约瑟课题组等合作的题为“Genomic insight into balancing high yield, g...
Genomic analyses reveal the genetic basis of early maturity and identification of loci and candidate genes in upland cotton (Gossypium hirsutum L.)
陆地棉 全基因组 重测序方法 SNP变异图谱
2024/5/17
本研究利用收集的436份国内外变异广泛的陆地棉材料，采用全基因组重测序方法，构建了群体的SNP变异图谱，通过对包含136份早熟棉资源在内的356份陆地棉材料进行深度重测序，并结合公共数据库中的80份陆地棉材料共获得了10,118,884个高质量的SNPs。利用全基因组关联分析（GWAS）鉴定到控制陆地棉早熟性的307个显著遗传位点和重要调控基因。两个早熟遗传热点区域位于 D03和A05&...

栽培陆地棉 纤维品质 优异位点 分子育种
2024/4/16
栽培陆地棉广泛种植于世界各地，是最重要的天然纤维来源，纤维品质直接决定了其经济价值。国内外棉花育种家开展了广泛的远缘杂交工作，将许多稀有的重要基因转移到栽培陆地棉中提高纤维品质，但并未对这些基因进行深入研究。本研究分析了超过3000份棉花种质资源，总计调查了近80000个纤维品质数据，全面剖析和评估了现存陆地棉种质资源中纤维品质相关的优异位点，并从远缘杂交渐渗系中鉴定到两个新的与纤维品质密切关联的...
