DATA ACCESIBILITY
Terpene synthases protein accession numbers shown in Supporting Information Fig. S1 are available in public databases of the Joint Genome Institute (JGI ) and the National Center for Biotechnology Information (NCBI). Terpene synthases and β-tubulin gene accession numbers of T. gamsii T6085 used for gene expression analyses are available in NCBI as: XM_024549662 (β-tubulin ), XM_018805995 (ts1 ), XM_018801080 (ts3 ), XM_024550105.1 (ts4 ), XM_018800313 (ts5 ), XM_018800491 (ts6 ), XM_024549058 (ts7 ), XM_018806700 (ts11 ), XM_018800875 (tri5 ). Nucleotide sequence of ts9 gene was extracted from the whole genome sequence of T. gamsii T6085 (NCBI WGS Project accession number JPDN00000000) using the JGI protein code Trigam1_9898.
