摘　　要：本文对蛋白质组学在植物逆境适应中的作用进行了研究,重点关注干旱、盐碱、高温和低温逆境下的蛋白质变化及其调控机制。研究表明,蛋白质组学技术,包括质谱分析、二维凝胶电泳和液相色谱,能够全面揭示植物在不同逆境条件下的蛋白质表达谱和功能变化。结果显示,在干旱条件下,植物体内热激蛋白和抗氧化酶显著上调,有助于应对水分胁迫;在盐碱逆境中,离子通道蛋白和渗透调节蛋白的变化增强了植物的盐碱耐受性;而高温和低温逆境下,热激蛋白和冷激蛋白的表达变化则帮助植物抵御温度极端的影响。这些发现为理解植物的逆境应对机制和提升作物抗逆性提供了重要依据。This paper investigated the role of proteomics in plant stress adaptation,focusing on protein changes and their regulation mechanisms under drought,salinity,high and low temperature stress.We show that proteomic techniques,including mass spectrometry,two-dimensional gel electrophoresis,and liquid chromatography,are able to comprehensively reveal protein expression profiles and functional changes in plants under different stress conditions.The results showed that heat shock proteins and antioxidant enzymes in salinity stress enhance the salinity tolerance,and heat shock protein changes in heat and cold stress stress help plants to resist the effects of temperature.These findings provide an important basis for understanding plant stress response mechanisms and improving crop stress resistance.
