郭旺珍 经济作物 发育
2024/6/11
干旱是限制植物种植分布、生长发育以及作物产量的主要非生物胁迫因素之一。棉花是重要的经济作物，新疆是中国棉花种植的主要地区，占全国棉花种植面积80%以上。干旱胁迫是影响新疆棉花生产重要的非生物胁迫因素。挖掘关键抗旱基因，揭示棉花对干旱胁迫的应答机制，培育耐逆新材料和新品种，不仅具有重要的科学研究价值，也是服务棉花可持续发展的重要保障。NAC转录因子在植物非生物胁迫信号中起着重要的转录调控作用。然而，...

郭旺珍 脂肪酸 棉纤维发育
2023/10/28
脂肪酸和脂质对植物细胞伸长具有重要作用，其功能特征涉及维持细胞结构完整性，为多种代谢过程提供能量，作为信号转导介质参与多种信号通路等。脂质转运蛋白(LTP)是一种含有疏水腔的蛋白质，这种结构特征使 LTP 蛋白能够结合和转运复杂的脂类物质。棉纤维是世界上最重要的天然纺织原料，也是植物中最长的单细胞。脂类物质的含量及组成对棉纤维发育具有重要调节作用，其中神经酰胺类脂质在棉纤维伸长时期含量最为丰富,且...
Genome-wide identification of NF-YA gene family in cotton and the positive role of GhNF-YA10 and GhNF-YA23 in salt tolerance
全基因组分析 雷蒙德氏棉 亚洲棉 海岛棉 陆地棉
2024/5/17
本研究基于全基因组分析，在雷蒙德氏棉、亚洲棉、海岛棉和陆地棉基因组中分别鉴定得到16、16、31和29个NF-YA基因。通过进化树分析将NF-YA基因分为4个亚组。结构分析表明NF-YA基因在棉属进化过程中相对保守。荧光定量显示GhNF-YAs可能通过ABA和 MeJA的调控通路响应盐和干旱。VIGS沉默GhNF-YA10和GhNF-YA23的表达，能显著降低棉花对盐的抗性，表明这两个基...
Open-Bud Duplicate Loci Are Identified as MML10s, Orthologs of MIXTA-Like Genes on Homologous Chromosomes of Allotetraploid Cotton
棉花 开发花蕾 ob1基因
2024/5/17
通过图位克隆鉴定了控制开发花蕾的ob1基因，是位于D13染色体上的MIXTA-like MYB基因，解释了ob2位点的因果变异。运用全基因组转录组分析技术，发现ob突变体中部分MYB基因和细胞壁生物发生、毛状体分化、细胞分裂素信号转导和细胞分裂的相关基因受到抑制，花瓣生长可能因此受到抑制。
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&...
Systematical characterization of YUCCA gene family in five cotton species, and potential functions of YUCCA22 gene in drought resistance of cotton
棉花 YUC基因家族 生长素合成
2024/5/17
生长素在植物的正常生长发育中起着至关重要的作用。TAA/YUCCA基因家族编码色氨酸氨基转移酶（tryptophan aminotransferase），是生长素合成的关键酶。然而，棉花中YUCCA（YUC）基因家族尚未见报道。为了揭示YUC基因在棉花中的功能，我们系统地鉴定了五个棉种中的YUC基因家族，包括成员分析、特征描述、基因组内复制和共线关系。转录组学分析表明，GhYUCs参与了棉花的非生...
