药用植物化感物质合成、转运释放机制及其影响的研究进展OA

Allelochemicals have represented specific secondary metabolites that affect plant photosynthesis,respiration,intercellular transport,and the induction of cell death;they have also served as primary initiators of continuous cropping obstacles in medicinal plants.Research on allelochemicals has primarily concentrated on their biosynthesis,transport,and interactions with soil microbial communities,as well as their impacts on soil nutrient cycling.Based on these established foundations,this study has summarized the synthesis,transport,and release pathways of allelochemicals in medicinal plants,alongside the relevant influencing factors.Furthermore,it has explored the interaction mechanisms between allelochemicals and the soil microenvironment,clarifying how these compounds shape soil physicochemical properties and specific microbial communities during the secondary metabolic processes of medicinal plants.These studies have further elucidated the biotic and abiotic stress mechanisms governing the secondary metabolism of medicinal plants and their regulatory roles.Consequently,this work has enriched the interaction framework between medicinal plants and the soil microenvironment,as well as the'metabolic landscape'theory,thereby providing a reference for the ecological cultivation and quality improvement of medicinal plants.
