Gene structure and classification of putative intact VvTPS. Exon-intron structures were predicted and manually curated for the putative intact VvTPS gene models. Green arrows and black lines represent at scale protein coding exons and introns, respectively. The conserved motifs RR(x)8W and DDxxD are represented by yellow and red boxes, respectively. Green circles indicate the prediction of an N-terminal plastidial targeting peptide. Classification into subfamilies is based on phylogenetic analyses supported, where applicable, by corresponding functional data. Subfamilies TPS-a, TPS-b and TPS-g are characterized by a highly conserved structure of seven exons. The three VvTPS genes of subfamilies TPS-c and TPS-e have distinct structures with 13 to 15 exons.
