Phylogeny of the NRPD2/E2-like gene family in Violaceae. Bootstrap support values (1000 replicates) are indicated above (MP) and below (ML) branches, respectively. Names of pseudogenes are capitalized. A. Violaceae phylogeny inferred by ML analysis of the four genes atpB, matK, rbcL and 16S. Sequence data were obtained from Tokuoka [25] with an additional matK sequence of Cubelium concolor from GenBank (EF135550, as Hybanthus concolor). Names of taxa not included in phylogeny B are underlined. B. Phylogeny of NRPD2/E2 paralogs in Violaceae inferred by ML analysis. C. Tree reconciliation between the NRPD2/E2 gene tree (B) and the Violaceae organism tree (A), using the GeneTree software. The two inferred gene duplication events and three gene loss events are indicated.
