Chamaecyparis formosensis is a precious conifer endemic in Taiwan. To understand the sesquiterpene synthesis mechanism in this tree, full-length cDNA of a putative sesquiterpene synthase (sesqui-TPS), designated Cf-Cad , was obtained by rapid amplifi cation of complementary DNA ends-polymerase chain reaction. Cf-Cad is 1812 bp in length. To identify its function, recombinant protein from Escher...
