Abstract

Abstract: 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.

Key words: phytohormone, strigolactone, structural analog, fluorescent probe, plant growth regulators

摘要： 独脚金内酯（strigolactone，SLs）作为一类由类胡萝卜素衍生的植物激素，在调控植物生长发育、形态建成及逆境响应等生理过程中发挥重要作用。在塑造作物株型、杀灭寄生杂草和促进微生物有益共生等方面显示出巨大的应用潜力。开发结构稳定、价格低廉、活性增强的SLs类似物具有重要的理论和应用价值。本文系统综述了独脚金内酯的生物学功能及其分子机制，重点探讨了结构修饰对其生物活性的影响，并详尽介绍了荧光探针技术在独脚金内酯信号转导研究中的应用进展，但目前从基础结合研究迈向活体、多组分、实时动态成像，以及开发高通量筛选专用探针工具仍面临核心挑战。本文为深入解析独脚金内酯的作用机制及开发新型植物生长调节剂提供理论依据和研究思路。
