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...
提高水稻氮素利用效率（NUtE）对于最大限度地提高未来粮食生产同时最大限度地减少环境威胁至关重要，但目前仍缺乏有关其变异及其潜在调控因素的知识。为了进一步理解水稻的NUtE全球变化及其背后的影响因素，本文结合同行评议文献数据和大规模实地调查，编制了一个新的水稻地上生物量和氮含量数据集。本研究的目的如下：(1)揭示水稻NUtE的空间格局；(2)明确决定水稻NUtE的人类活动、气候和土壤特征等因素；(...

GhLUX1 and GhELF3 Are Two Components of the Circadian Clock That Regulate Flowering Time of Gossypium hirsutum
陆地棉 开花时间 调控机制
2024/4/16
植物从营养生长向生殖生长转变的时机受到多个复杂环境因素和内在因素的调控，只有适时的花芽起始和开花，植物才能在适宜的环境中完成生殖生长，从而成功的繁殖后代。季节性的光周期变化作为最可靠的外界信号，是植物判断外界环境条件是否适合生殖生长的重要依据。植物通过生物钟感知日长变化，调节自身生理活动与昼夜变化相协调，然而生物钟在光周期调控陆地棉开花时间中的作用尚是完全空白。本研究通过同源比对，在陆地棉中鉴定到...
Gibberellin biosynthesis inhibitor mepiquat chloride enhances root K+ uptake by modulating plasma membrane H+-ATPase.
MC浸种 钾离子吸收 棉花生产
2024/5/17
缩节胺(MC)作为一种赤霉素生物合成抑制剂，可以增加棉花对钾离子的吸收，从而对棉花生长产生积极调节作用，但是潜在生理机制尚不清楚。本研究利用非损伤微测技术测定表明，除了增加根生物量之外，MC浸种还可以通过增加钾离子流入和/或减少幼苗根尖的钾离子外排来增加钾离子吸收。此外，该研究发现，MC处理可以引起质膜超极化，可以通过增强H +-ATPase的基因表达（HA2/5/11）、蛋白积累（GhAHAs总...
