独脚金内酯（SL）是由类胡萝卜素衍生的植物次生代谢产物。SL最初是作为根寄生植物独脚金（Striga spp.）和肉苁蓉（列当属和蒲葵属），然后被发现是与80%以上的陆地植物形成共生关系的丛枝菌根（AM）真菌的宿主识别信号。除了SL在根际的这些功能之外，SL还被证明是一类新型的植物激素，调节芽和根的结构、光形态建成和次生生长。在这一章中，我们将重点介绍SL的不同化学成分，并讨论植物为什么以及如何产生如此多的独脚金内酯。
Strigolactones (SLs) are plant secondary metabolites derived from carotenoids. SLs were originally isolated as germination stimulants for root parasitic plants witchweeds (Striga spp.) and broomrapes (Orobanche and Phelipanche spp.), and then found as host recognition signals for arbuscular mycorrhizal (AM) fungi with which >80% land plants form a symbiotic relationship. In addition to these functions of SLs in the rhizosphere, SLs have been shown to act as a novel class of plant hormone regulating shoot and root architecture, photomorphogenesis, and secondary growth. In this chapter, we will focus on diverse chemistry of SLs and discuss why and how do plants produce so many strigolactones.
