detected in many compositae plant species and were reported to exhibit various pharmacological activities. So far, the gene encoding junenol synthase has never been isolated. Here we report the molecular cloning and functional analysis of a 10-epi-junenol synthase from Inula hupehensis (designated IhsTPS1). IhsTPS1 converts the substrate farnesyl diphosphate into multiple sesquiterpenes with the product
已在许多菊科植物物种中检测到了基于朱诺醇的大地甘露内酯,据报道其具有多种药理活性。迄今为止,从未分离出编码junenol合酶的基因。在这里,我们报告了来自湖南菊(Inula hupehensis)(命名为IhsTPS1)的10- Epi- junenol合酶的分子克隆和功能分析。IhsTPS1将底物法呢基二磷酸酯转化为多种倍半萜烯,其中产物10-表位-芥子醇为主要成分。IhsTPS1的转录水平与10-表柔红醇在hupehensis器官中的积累模式密切相关,支持其在体内的生化作用。
