盐害是制约全世界作物生长的主要非生物胁迫之一，全球有6%土地和20%灌溉用地受到盐害影响，严重制约了农作物生长发育和产量。水稻作为全球主要粮食作物之一，对盐胁迫敏感。盐胁迫条件下，水稻种子萌发和幼苗形态建成显著受抑制，严重制约了我国水稻直播的推广和盐碱地区耕地利用。因此，挖掘鉴定控制水稻种子萌发的关键基因，阐明其在盐胁迫条件下调控种子活力的分子机制，对培育适合盐碱地生长的种子高活力耐盐水稻品种和保...
Improvement of plant tolerance to drought stress by cotton tubby-like protein 30 through stomatal movement regulation
棉花 气孔运动 GhTULP30 干旱胁迫
2024/4/16
棉花是一种重要的工业作物，逐渐转向在干旱地区种植。然而，参与植物响应各种胁迫的Tubby-like protein，TULP在棉花中很少被报道。本研究通过调节气孔运动，展示了GhTULP30对植物耐受干旱胁迫的改进。GhTULP30在酵母中的异源表达显著提高了其抗盐和干旱耐受性。GhTULP30的过表达使得拟南芥种子在种子萌发期间更加抵御干旱和盐胁迫，并且在干旱胁迫条件下提高了该植物的气孔关闭速度...

Cotton DMP gene family: characterization, evolution, and expression profiles during development and stress
棉花 DMP 基因家族 系统分析
2024/4/16
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。
GhN/AINV13 positively regulates cotton stress tolerance by interacting with the 14–3-3 protein
GhN/AINV13 14-3-3蛋白互作 棉花抗逆
2024/5/17
GhN/AINV13通过与14-3-3蛋白互作正调控棉花抗逆能力中性/碱性转化酶(N/AINVS)是植物中具有重要作用的蔗糖水解酶。在本研究中，分别在雷蒙德氏棉、非洲棉、亚洲棉、陆地棉、海岛棉中鉴定到15、15、15、29以及30个中性/碱性转化酶基因。除了前人发现的α和β亚族之外，我们的研究中首次发现了一个新亚族。基因的共线性研究表明，全基因组复制(WGD)和多倍体化是异源多倍体棉N/AINV基...
