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...
