This review summarizes the physiological, biochemical, and molecular regulatory network changes in plants in response to high temperature. With the continuous rise in temperature, high temperature has become an important issue limiting global plant growth and development, affecting the phenotype and physiological and biochemical processes of plants and seriously restricting crop yield and tree growth speed. As sessile organisms, plants inevitably encounter high temperatures and improve their heat tolerance by activating molecular networks related to heat stress, such as signal transduction, synthesis of metabolites, and gene expression. Heat tolerance is a polygenic trait regulated by a variety of genes, transcription factors, proteins, and metabolites. Therefore, this review summarizes the changes in physiological, biochemical and molecular regulatory networks in plants under high-temperature conditions to lay a foundation for an in-depth understanding of the mechanisms involved in plant heat tolerance responses.
本综述总结了植物应对高温时在生理、生化和分子调控网络方面的变化。随着温度的持续升高，高温已成为限制全球植物生长和发育的重要问题，影响植物的表型和生理生化过程，严重限制了作物产量和树木生长速度。作为固着生物，植物不可避免地会遇到高温，并通过激活与热应激相关的分子网络来提高其耐热性，如信号转导、代谢物的合成和基因表达。耐热性是一种受多种基因、转录因子、蛋白质和代谢物调控的多基因性状。因此，本综述总结了高温条件下植物生理、生化和分子调控网络的变化，为深入了解植物耐热性响应的机制奠定了基础。
