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.
热应激（HS）会影响植物的生长和发育，并降低作物产量。为了应对 HS，植物已经进化出了几种复杂的策略。植物中主要的 HS 反应涉及热激转录因子和热激蛋白（HSPs）的激活。植物还会部署更先进的表观遗传机制来应对反复出现的 HS 条件。此外，有益微生物可以重新编程植物的表转录组，诱导耐热性，并有可能通过减轻 HS 对生长和发育的抑制来提高作物产量生产力。我们总结了植物表观遗传调控的最新进展，并强调了微生物介导的植物耐热性。
