中国科学院华南植物园博士研究生赖丁王等在王昌虎副研究员和区永祥研究员指导下，尝试利用模式生物裂殖酵母以证实上述推测。他们通过酵母双杂交、染色质免疫共沉淀和基因表达定量分析等手段进行了分子水平上的验证，揭示出了AtOXS3在酵母中介导胁迫抗性的相关分子机理。
GhTULP34, a member of tubby-like proteins, interacts with GhSKP1A to negatively regulate plant osmotic stress
Tubby-like 蛋白基因 环境胁迫 棉花 组织发育

2024/5/17
Tubby-like蛋白基因(TULPs)以大型多基因家族的形式存在，在环境胁迫中发挥重要作用。然而，关于棉花中TULP家族基因的研究却知之甚少。本研究系统地对4种棉花TULPs的隶属关系、特征及其进化关系进行了鉴定和分析。转录组分析表明GhTULPs参与了环境胁迫和棉花组织发育。同时，我们还预测和分析了TULPs可能的分子调控机制和功能。GhTULP34作为候选基因，在盐胁迫下显著降低转基因拟南...
