独脚金内酯（SLs）最初被认为是根寄生杂草的发芽促进剂，现在被认为是共生丛枝菌根真菌的菌丝分支因子和一类抑制芽分枝的新型植物激素。本研究对包括农作物、杂草和观赏植物在内的13种菊科植物根系分泌物中的SLs进行了表征。高效液相色谱/串联质谱（LC-MS /MS）分析表明，所有菊科植物均有已知的SLs，除向日葵（Helianthus annuus）外，这些SLs在保留时间内具有较高的萌发刺激活性。这些菊科植物所分泌的两种主要的硫代化合物是醋酸环凤尾鱼酯和环凤尾鱼酯。本研究在几种菊科植物的根分泌物中检测到5-脱氧马癸醇和7-羟基乙酸酯。
Strigolactones (SLs), originally characterized as germination stimulants for root parasitic weeds, are now recognized as hyphal branching factors for symbiotic arbuscular mycorrhizal fungi and as a novel class of plant hormones inhibiting shoot branching. In the present study, SLs in root exudates of 13 Asteraceae plants including crops, a weed, and ornamental plants were characterized. High performance liquid chromatography/tandem mass spectrometry (LC–MS/MS) analyses revealed that all the Asteraceae plants examined exuded known SLs and, except for sunflower (Helianthus annuus), high germination stimulant activities at retention times corresponding to these SLs were confirmed. The two major SLs exuded by these Asteraceae plants were orobanchyl acetate and orobanchol. 5-Deoxystrigol and 7-hydroxyorobanchyl acetate were detected in root exudates from several Asteraceae species examined in this study.
