Sensing and response to high temperatures are crucial to prevent heat-related damage and to preserve cellular and metabolic functions. The response to heat stress is a complex and coordinated process that involves several subcellular compartments and multi-level regulatory networks that are synchronized to avoid cell damage while maintaining cellular homeostasis. In this review, we provide an insight into the most recent advances in elucidating the molecular mechanisms involved in heat stress sensing and response in Marchantia polymorpha. Based on the signaling pathways and genes that were identified in Marchantia, our analyses indicate that although with specific particularities, the core components of the heat stress response seem conserved in bryophytes and angiosperms. Liverworts not only constitute a powerful tool to study heat stress response and signaling pathways during plant evolution, but also provide key and simple mechanisms to cope with extreme temperatures. Given the increasing prevalence of high temperatures around the world as a result of global warming, this knowledge provides a new set of molecular tools with potential agronomical applications.

地黄热应激：动态反应的感知和机制

对高温的感知和响应对于防止与热相关的损伤以及保持细胞和代谢功能至关重要。对热应激的反应是一个复杂而协调的过程，涉及多个亚细胞区室和多级调节网络，这些网络是同步的，以避免细胞损伤，同时保持细胞稳态。在这篇综述中，我们提供了对阐明多形马钱蒂亚热应激传感和响应的分子机制的最新进展的见解。. 基于在 Marchantia 中鉴定的信号通路和基因，我们的分析表明，尽管具有特定的特殊性，但热应激反应的核心成分在苔藓植物和被子植物中似乎是保守的。苔类不仅是研究植物进化过程中热应激反应和信号通路的有力工具，而且还提供了应对极端温度的关键而简单的机制。鉴于全球变暖导致全球高温日益流行，这些知识提供了一套具有潜在农艺应用潜力的新分子工具。
