SUMMARY Heat stress impacts all aspects of life, from evolution to global food security. Therefore, it becomes essential understand how plants respond heat stress, especially in the context climate change. The response (HSR) involves three main components: sensing, signal transduction, and cellular reprogramming. Here, I focus on sensing component. How can cells detect if is not a signalling particle? To answer this question, have looked at molecular definition stress. It be defined as any particular rise optimum growth temperature that leads higher‐than‐normal levels reactive species macromolecular damage biological membranes, proteins, nucleic acid polymers (DNA RNA). precisely these stress‐specific alterations are detected by sensors, upon which they would immediately trigger appropriate level HSR. In addition, work towards thermotolerance complemented second type response, here called homeostasis (CHR). Upon mild extreme changes, CHR triggered plant thermosensors, responsible for monitoring information. sensors thermosensors distinct types molecules, each with unique modes activation functions. While many recent reviews provide comprehensive overview there remains notable gap review literature regarding an in‐depth analysis sensors. attempt summarise our current knowledge involved triggering
