苜蓿 抗寒性 秋眠性
2024/5/30
多年生苜蓿以根的形式越冬，因此，苜蓿的抗寒性以及成功越冬的关键在于其根部的抗寒性。在没有叶绿体结构不能进行光合作用的根部，呼吸作用是维持根部细胞生长所需能量ATP的唯一途径。新疆农业大学刘美君副教授团队选用不同秋眠级的新牧4号(秋眠级为2) 和甘农5号(秋眠级为8) 的紫花苜蓿为试验材料，研究发现，低温显著影响了苜蓿根系细胞呼吸代谢，细胞线粒体电子传递链复合体复合体II、III和IV受抑明显致使氧...
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...
