Higher temperatures associated with climate change often increase the severity of plant diseases. An understanding of how plants respond to pathogens during high temperature stress is required for crop improvement, but the molecular mechanisms underlying this response are largely unknown. Mechanistic research has primarily focused on plant responses during either single stresses or heat-induced loss of single gene resistance. Transcriptome analyses of plant responses to a single stress compared to combined-stresses reveal significant differences showing that single-stress response studies are inadequate for determining the mechanisms of high temperature-induced disease susceptibility. To combat plant disease in light of climate change, future research will require comprehensive study designs and analyses.

高温引起的植物病害敏感性：超过其各部分的总和。

与气候变化相关的较高温度通常会加剧植物病害的严重性。作物改良需要了解植物在高温胁迫下如何对病原体作出反应，但这种应答所基于的分子机制在很大程度上尚不清楚。机理研究主要集中在单胁迫或热诱导的单基因抗性丧失期间的植物响应。与单一胁迫相比，植物对单一胁迫的响应的转录组分析显示出显着差异，表明单一胁迫响应研究不足以确定高温诱导的疾病易感性机制。为了根据气候变化与植物疾病作斗争，未来的研究将需要全面的研究设计和分析。
