Strigolactones (SLs) are a class of plant hormones that play vital roles not only in the control of plant branching and early seedling growth, but also in mediating rhizospheric communication with root parasitic plants and symbiotic fungi1. SL receptors in host and parasitic plants have recently been identified to be a group of α/β hydrolases2,3,4,5,6,7, but not in arbuscular mycorrhizal fungi, which form symbiosis with more than 80% of land plants8.

简单的β-内酯是stragolactone受体的有效不可逆拮抗剂

Strigolactones（SLs）是一类植物激素，不仅在控制植物分支和早期幼苗生长中，而且在介导根寄生植物和共生真菌的根际交流中都起着至关重要的作用。最近已确定寄主植物和寄生植物中的SL受体是一组α/β水解酶2、3、4、5、6、7，但在丛枝菌根真菌中却没有，后者与80％以上的陆地植物共生。
