Strigolactones(SLs),a novel class of carotenoid-derived phytohormones,play crucial roles in regulating various physiological processes including plant growth,development,morphogenesis,and stress responses.It demonstrates great application potential in shaping crop architecture,eliminating parasitic weeds,and promoting beneficial microbial symbiosis.Developing SLs analogs with stable structures,low costs,and enhanced activity holds significant theoretical and practical value.This review systematically summarizes the biological functions and molecular mechanisms of SLs,with particular emphasis on how structural modifications influence their bioactivity.Furthermore,it provides a comprehensive overview of recent advances in fluorescent probe technology for studying strigolactone signaling pathways.There are still core challenges in moving from basic combination studies to in vivo,multi-component,real-time dynamic imaging,and in developing dedicated probe tools for high-throughput screening.This paper provides a theoretical basis and research ideas for a deeper understanding of the mechanism of action of strigolactones and for the development of new plant growth regulators.
