The rapid development of global industrialization has led to serious environmental problems, among which global warming has become one of the major concerns. The gradual rise in global temperature resulted in the loss of food production, and hence a serious threat to world food security. Rice is the main crop for approximately half of the world's population, and its geographic distribution, yield, and quality are frequently reduced due to elevated temperature stress, and breeding rice varieties with tolerance to heat stress is of immense significance. Therefore, it is critical to study the molecular mechanism of rice in response to heat stress. In the last decades, large amounts of studies have been conducted focusing on rice heat stress response. Valuable information has been obtained, which not only sheds light on the regulatory network underlying this physiological process but also provides some candidate genes for improved heat tolerance breeding in rice. In this review, we summarized the studies in this field. Hopefully, it will provide some new insights into the mechanisms of rice under high temperature stress and clues for future engineering breeding of improved heat tolerance rice.
全球工业化的快速发展导致了严重的环境问题，其中全球变暖已成为主要关注点之一。全球气温的逐渐上升导致粮食产量损失，从而对世界粮食安全构成严重威胁。水稻是世界上约一半人口的主要作物，由于温度胁迫升高，其地理分布、产量和品质经常下降，培育耐热胁迫的水稻品种具有极其重要的意义。因此，研究水稻对热胁迫的分子机制至关重要。在过去几十年中，针对水稻热胁迫响应开展了大量研究。已获得了有价值的信息，这不仅揭示了这一生理过程背后的调控网络，还为水稻耐热性改良育种提供了一些候选基因。在本综述中，我们总结了该领域的研究。希望它能为高温胁迫下水稻的机制提供一些新见解，并为未来耐热性改良水稻的工程育种提供线索。
