摘要: 脯氨酸(proline,Pro)积累是植物在生物和非生物胁迫下的一种重要的代谢适应性机制,其主要功能是作为渗透调节物质,维持细胞内外渗透平衡,增强植物抗逆性。此外在自由基清除、降低细胞酸性及作为金属螯合剂等方面也具有重要作用。本文主要从脯氨酸的合成与降解、关键酶基因研究现状、生物学功能、生理毒性、离子动态平衡、作用机制及其在植物中抗逆表现等方面的研究进行综述,旨在全面了解有关脯氨酸的研究现状,为其在植物抗逆方面的研究提供参考。

Abstract: Proline(Pro) accumulation is an essential metabolic adaptation mechanism of plants under biological and abiotic stress. Its primary function is to act as an osmotic regulatory substance,maintain the osmotic balance inside and outside the cell,and enhance plant stress resistance. It also plays a vital role in free radical scavenging,reducing cellular acidity,and acting as a metal-chelating agent. This paper mainly reviewed the synthesis and degradation of proline,the research status of crucial enzyme genes,biological function,physiological toxicity,ion homeostasis,mechanism of action,and its performance of stress resistance in plants,etc.,to comprehensively understand the research status of proline and provide a reference for its research on plant stress resistance.

Key words: proline, adversity stress, stress resistance, mechanism
