Strigolactones (SLs) are small carotenoid-derived molecules that possess a wide spectrum of functions, including plant hormonal activities and chemical mediation of rhizosphere communication with both root parasitic plants and symbiotic arbuscular mycorrhizal fungi. Chemicals that regulate the functions of SLs may therefore have the potential to become widely used in agricultural applications. For example, various SL analogs and mimics have been developed to reduce the seed banks of root parasites in the field. Other analogs and mimics act selectively to suppress branching, with weak, or no stimulation, of germination in root parasites. In addition, some antagonists for SL receptors have been developed based on the mechanisms of SL perception. A better understanding of the modes of action of SL perception by various receptors will help to support the design of SL analogs, mimics, and antagonists with high activity and selectivity. Here, we review the compounds reported so far from the viewpoint of their selectivity to their targets, and the possibilities for their use in agriculture.
独脚金内酯（SLs）是一类小分子类胡萝卜素衍生化合物，具有广泛的功能，包括植物激素活性和根际与根寄生植物和共生菌根真菌化学信号转导。因此，调节 SL 功能的化学物质有可能在农业应用中得到广泛应用。例如，已经开发了各种 SL 类似物和模拟物来减少田间根寄生植物的种子库。其他类似物和模拟物选择性地抑制分枝，对根寄生植物的萌发有弱刺激或无刺激。此外，还基于 SL 感知的机制开发了一些 SL 受体拮抗剂。更好地了解各种受体对 SL 感知的作用模式将有助于支持具有高活性和选择性的 SL 类似物、模拟物和拮抗剂的设计。在这里，我们从对目标的选择性的角度回顾迄今为止报道的化合物，并探讨它们在农业中的应用可能性。
