Figure 1From: Terpene synthases and their contribution to herbivore-induced volatile emission in western balsam poplar (Populus trichocarpa)Phylogenetic tree of full-length terpene synthases (TPS) from Populus trichocarpa . The phylogenetic relationship of 38 P. trichocarpa TPS is shown. PtTPS1-4 and IPS have been characterized in previous studies. The tree was inferred with the neighbor-joining method and n = 1000 replicates for bootstrapping. Bootstrap values are shown next to each node. IPS, isoprene synthase; STS, sesquiterpene synthase; MTS, monoterpene synthase; CDS, copalyl diphosphate synthase; DTS, diterpene synthase; KS, kaurene synthase. TPS-a to h represent TPS subfamilies.Back to article page
