Abstract Plant hormones play important roles in controlling how plants grow and develop. While metabolism provides the energy needed for plant survival, hormones regulate the pace of plant growth. Strigolactones (SLs) were recently defined as new phytohormones that regulate plant metabolism and, in turn, plant growth and development. This group of phytohormones is derived from carotenoids and has been implicated in a wide range of physiological functions including regulation of plant architecture (inhibition of bud outgrowth and shoot branching), photomorphogenesis, seed germination, nodulation, and physiological reactions to abiotic factors. SLs also induce hyphal branching in germinating spores of arbuscular mycorrhizal fungi (AMF), a process that is important for initiating the connection between host plant roots and AMF. This review outlines the physiological roles of SLs and discusses the significance of interactions between SLs and other phytohormones to plant metabolic responses.

独脚金内酯的作用：与其他植物激素的信号传递和串扰

摘要 植物激素在控制植物生长发育方面起着重要作用。新陈代谢提供植物生存所需的能量，而激素则调节植物生长的速度。独脚金内酯 (SLs) 最近被定义为新的植物激素，可调节植物代谢，进而调节植物生长和发育。这组植物激素来源于类胡萝卜素，并涉及广泛的生理功能，包括植物结构的调节（抑制芽生长和枝条分枝）、光形态发生、种子萌发、结瘤和对非生物因素的生理反应。SL 还在丛枝菌根真菌 (AMF) 的萌发孢子中诱导菌丝分枝，这一过程对于启动宿主植物根和 AMF 之间的连接很重要。
