[Abstract] Strigolactones (SLs) are carotenoid-derived signaling chemicals containing two lactone moieties in their structures and induce seed germination of root parasitic plants, Striga and Orobanche spp. In the rhizosphere, SLs are essential host recognition signals not only for root parasitic plants but also for arbuscular mycorrhizal fungi. In plants, SLs play important roles as plant hormones regulating shoot and root architecture. Plants produce only trace amounts of chemically unstable SLs, which makes it difficult to determine SL contents in plant tissues. Here, we describe how to extract and quantify sorgomol and 5-deoxystrigol, major SLs produced in sorghum roots.
[摘要] 独脚金内酯（SL）是类胡萝卜素衍生的信号化学品，其在其结构中含有两个内酯部分，并诱导根寄生植物，Striga和Orobanche的种子发芽。 在根际中，SLs是必不可少的宿主识别信号，不仅对于根部寄生植物，而且对于丛枝菌根真菌。 在植物中，SLs作为调节枝条和根构造的植物激素发挥重要作用。 植物仅产生痕量的化学不稳定的SL，这使得难以确定植物组织中的SL含量。 在这里，我们描述如何提取和量化sorgomol和5-deoxystrigol，主要SLs高粱根中产生。
