Phospholipase Dα6 and phosphatidic acid regulate gibberellin signaling in rice
gibberellin signaling GID1 receptor phosphatidic acid Phospholipase rice
2023/4/21
Phospholipase D (PLD) hydrolyzes membrane lipids to produce phosphatidic acid (PA), a lipid mediator involved in various cellular and physiological processes. Here, we show that PLDa6 and PA regulate ...
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...
