Fig. 2

Putative gene tree of CYC-like paralogs in Knautia macedonica. Duplication events that span the core eudicots are shown in black (CYC1), blue (CYC2), and red (CYC3). Black circles label duplications that span the Caprifoliaceae. Gray circles indicate a putative Dipsacaceae duplication. A single paralog was successfully cloned and used in qPCR experiments from each major clade. Additional paralogs are hypothesized within other groups of Dipsacaceae and are shown as dashed lines with putative copy numbers indicated inside triangles
