The increased prevalence of high temperatures （HTs） around the world is a major global concern, as they dramatically affect agronomic productivity. Upon HT exposure, plants sense the temperature change and initiate cellular and metabolic responses that enable them to adapt to their new environmental *** the mechanisms by which plants cope with HT will facilitate the development of molecular markers to enable the production of plants with improved thermotolerance. In recent decades, genetic, physiological, molecular, and biochemical studies have revealed a number of vital cellular components and processes involved in thermoresponsive growth and the acquisition of thermo- tolerance in plants. This review summarizes the major mechanisms involved in plant HT responses, with a special focus on recent discoveries related to plant thermosensing, heat stress signaling, and HT-regulated gene expression networks that promote plant adaptation to elevated environmental temperatures.

服务贸易作为我国国际贸易的重要组成部分,在“双循环”视域下我国稳外贸促发展中发挥重要作用。本文基于我国2016-2022年30个省域样本数据,就服务贸易发展对我国出口韧性的影响效应进行实证研究。研究发现,服务贸易发展能够对我国出口韧性产生正向促进作用,但不同细分类型服务贸易发展对我国出口韧性的影响存在较为明显的差异性。其中,服务贸易出口对我国出口韧性的正向促进作用最强;进一步的,服务贸易发展对我国出口韧性的影响还存在明显区域异质性,整体上表现为东中西依次梯度递减的特征。最后,本文从强化服务贸易发展顶层设计、加快推进数字服务贸易发展、加强服务贸易的国际合作、重点打造若干服务贸易发展高地四个方面提出了通过服务贸易高质量发展助力我国出口韧性提升的政策建议。
