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...
Effectiveness of phosphorus application in improving regional soybean Yields under drought stress: A multivariate regression tree analysis
Soybean yield variability phosphorus drought strategy threshold
2011/1/13
Scarcity of water often reduces the regional production of soybean (Glycine max (L.) Merr.) in many areas where it is grown. Contemporary climate change is characterized by increase in frequency and i...
