5-氨基乙酰丙酸在植物非生物胁迫与生长中的作用研究OA北大核心CSTPCD

To develop more effective strategies for enhancing abiotic stress resistance in horticultural plants,this study reviews the biosynthesis pathways of 5-aminolevulinic acid(ALA)and its mechanisms in improving plant tolerance to abiotic stress and regulating plant growth.The results indicated that:1)The biosynthesis of ALA mainly occurs through the C5 pathway and the Shemin pathway,which are emphasized in different organisms to adapt to their unique physiological and ecological needs.2)As a precursor of porphyrin compounds,ALA plays a crucial role in plant photosynthesis and metabolic processes.3)ALA enhances plant stress tolerance by influencing gene expression,metabolic regulation,and signal transduction.4)Further research will focus on exploring the specific molecular mechanisms and signaling pathways of ALA,as well as developing new approaches to utilize ALA for improving crop quality and increasing agricultural productivity.Overall,ALA demonstrates significant research potential and practical applications in agricultural production and scientific research.However,to fully harness its potential and effectiveness,in-depth studies on its specific molecular mechanisms are required,as well as further identification of ALA's role as a plant signaling molecule and the existence of its specific receptors.The study not only provides more effective strategies for improving abiotic stress resistance in horticultural plants but also offer a theoretical basis for ensuring stable and sustainable crop production under the increasing challenges of global climate change and environmental stress.
