独脚金内酯（Strigolactones，SL）是一类独特的植物激素，对植物的生长发育具有重要的调控作用。除了作为激素的内源性功能外，SL还通过植物根系分泌来刺激与共生真菌的关键相互作用，但也可以被寄生植物利用来触发其种子萌发。在过去的十年中，由于他们作为植物激素的发现，SL的生物合成和信号通路的理解取得了迅速的进展。特别令人感兴趣的是天然SL的多样化及其在植物中通过其专用受体的感知、选择性和水解的确切模式。在这里，我们提供了一个概述SL感知的新兴领域，专注于典型的，非典型的，合成SL探针的多样性。此外，这篇评论提供了有用的结构的见解SL感知，精确的分子适应，定义受体-配体特异性，SL水解和其衰减的下游信号成分的机制。
Strigolactones (SLs) are a unique and novel class of phytohormones that regulate numerous processes of growth and development in plants. Besides their endogenous functions as hormones, SLs are exuded by plant roots to stimulate critical interactions with symbiotic fungi but can also be exploited by parasitic plants to trigger their seed germination. In the past decade, since their discovery as phytohormones, rapid progress has been made in understanding the SL biosynthesis and signaling pathway. Of particular interest are the diversification of natural SLs and their exact mode of perception, selectivity, and hydrolysis by their dedicated receptors in plants. Here we provide an overview of the emerging field of SL perception with a focus on the diversity of canonical, non-canonical, and synthetic SL probes. Moreover, this review offers useful structural insights into SL perception, the precise molecular adaptations that define receptor-ligand specificities, and the mechanisms of SL hydrolysis and its attenuation by downstream signaling components.
