| Research Abstract |
Higher land plants, angiosperm produces various bioactive diterpenoids as antibiotic, anti-feedant and plant hormones. The lower land plants, the moss, liverwort and fern produce the diterpenoids, however, the biosynthetic pathway of diterpenes have not been revealed in these lower plants. To elucidate the evolution of diterpene biosynthesis in land plants, diterpene synthetic genes in lower land plants was cloned, and the enzymatic functions were investigated. We herein demonstrate that the cloning of new diterpene cyclase genes from the fern, Selaginella moellendorffii and moss Hypnum plumaeforme. Additionally, we showed the detailed catalyzing mechanism of ent-kaurene synthese using the chimeric enzymes in the moss and liverwort.
