摘要

高温是几种主要的非生物胁迫之一，可导致作物产量的重大损失。热休克蛋白（HSPs）是抗热应激的关键成分。HSP70的辅助分子伴侣FES1A突变导致获得性耐热性缺陷。自噬是基础耐热性的正调节因子和热应激记忆的负调节因子，但其在获得性耐热性中的作用尚不清楚。我们发现阻断本构性自噬可以恢复拟南芥fes1a的热敏性。免疫印迹和蛋白质组学分析表明，挽救不是由于热休克蛋白水平升高。相反，蛋白质组学分析和共聚焦显微镜研究显示，敲除核心自噬相关（ATG）基因会导致过氧化物酶体的积累，从而上调过氧化物酶体内的代谢途径。过氧化物酶体的积累促进了at7fes1a中活性氧的清除和吲哚-3-乙酸（IAA）的产生。ABCD1/PXA1/CTS（一种过氧化物酶体atp结合盒转运蛋白）在atg7 fes1a中过表达，导致过氧化物酶体功能异常，进而导致温敏性异常。此外，我们发现外源施用吲哚-3-丁酸、IAA或萘-1-乙酸可恢复fes1a的热敏性。我们认为自噬对fes1a突变体的生存是有害的，fes1a突变体已经获得了热敏性。

期刊介绍： New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
