Changes in weather patterns with emerging drought risks and rising global temperature are widespread and negatively affect crop growth and productivity. In nature, plants are simultaneously exposed to multiple biotic and abiotic stresses, but most studies focus on individual stress conditions. However, the simultaneous occurrence of different stresses impacts plant growth and development differently than a single stress. Plants sense the different stress combinations in the same or in different tissues, which could induce specific systemic signalling and acclimation responses; impacting different stress-responsive transcripts, protein abundance and modifications, and metabolites. This mini-review focuses on the combination of drought and heat, two abiotic stress conditions that often occur together. Recent omics studies indicate common or independent regulators involved in heat or drought stress responses. Here, we summarize the current research results, highlight gaps in our knowledge, and flag potential future focus areas.
天气模式的变化伴随着新出现的干旱风险和全球气温上升，这些现象广泛存在并对作物生长和生产力产生负面影响。在自然界中，植物同时面临多种生物和非生物胁迫，但大多数研究集中在单一胁迫条件下。然而，不同胁迫同时发生对植物生长发育的影响与单一胁迫不同。植物在相同或不同组织中感知不同的胁迫组合，这可能会诱导特定的系统信号传导和适应性反应；影响不同的胁迫响应转录本、蛋白质丰度和修饰以及代谢物。本综述聚焦于干旱和高温这两种经常同时出现的非生物胁迫条件的组合。最近的组学研究表明，参与热胁迫或干旱胁迫反应的调控因子存在共同或独立的情况。在此，我们总结了当前的研究成果，突出了我们知识上的空白，并指出了未来潜在的重点研究领域。
