Abstract: Provided are a Cinnamomum burmannii monoterpene synthase CbTPS1, an amino acid sequence thereof, a nucleic acid molecule encoding the protein, an use thereof in preparing the monoterpene synthase, and a method for preparing dextrorotatory borneol by using the Cinnamomum burmannii monoterpene synthase CbTPS1.

Abstract: Provided are a Blumea balsamifera monoterpene synthase BbTPS3 and related biological materials thereof and use thereof. BbTPS3 is: A1) a protein having the amino acid sequence shown in SEQ ID NO: 2; A2) a fusion protein obtained by linking protein-tags at the N-terminus or/and the C-terminus of the protein shown in SEQ ID NO: 2; and A3) a protein having at least 90% identity and the same function as the protein shown in A1), which is obtained by performing substitution and/or deletion and/or addition of one or more amino acid residues on the amino acid sequence shown in SEQ ID NO: 2. BbTPS3 can catalyze GPP to form l-borneol, and can be used to regulate and produce plant monoterpene compounds and cultivate Blumea balsamifera (L.) DC.
