摘要：Heat stress (HS) affects plant growth and development, and reduces crop yield. To combat HS, plants have evolved several sophisticated strategies. The primary HS response in plants involves the activation of heat-shock transcription factors and heat-shock proteins (HSPs). Plants also deploy more advanced epigenetic mechanisms in response to recurring HS conditions. In addition, beneficial microbes can reprogram the plant epitranscriptome to induce thermotolerance, and have the potential to improve crop yield productivity by mitigating HS-induced inhibition of growth and development. We summarize the latest advances in plant epigenetic regulation and highlight microbe-mediated thermotolerance in plants.

高温胁迫影响植物生长发育，减少作物产量。为了对抗高温胁迫，植物已进化了几种复杂的策略。植物响应热胁迫初期激活热激转录因子和热激蛋白。植物还利用更高级的表观遗传机制来应对反复发生的热胁迫条件。此外，有益的微生物能够重组表位转录组诱导耐热性，并有可能通过缓解热胁迫诱导的生长和发育抑制来提升作物产量。此我们总结了最新表观遗传调控最近进展，并重点介绍微生物介导植物耐热性。
