Analysis of reaction products of the pairwise activity of MvCPS1 and MvELS. a Total ion chromatogram of reactions products derived from co-expression assays of MvCPS1 and MvELS in N. benthamiana. Compound 1, 9,13-epoxy labd-14-ene; compound 2 [16], labda-13(16),14-dien-9-ol (as verified by NMR analysis); compound 3, unidentified diterpenoid closely related to 9,13-epoxy labd-14-ene. b Mass spectra of compounds 1, 2, and 3. c Structure of labda-13(16),14-dien-9-ol as verified by NMR analysis (see Additional file 3: Figure S1 for details)
