Divergence times and large-scale GDs of Solanaceae.

The chronogram was estimated with treePL based on the ML tree of 419 concatenated genes. Numbered red and purple stars indicate the large-scale GDs identified in this study, with percentages and numbers of duplicated gene families shown for each node.

(A) Global climate curve over the last 65 million years (modified from Zachos et al., 2008). Major paleo-climatic events during this period are indicated: PETM (ETM1), Paleocene–Eocene Thermal Maximum 1; ETM2, Eocene Thermal Maximum 2; EECO, Early Eocene Climatic Optimum; MECO, Mid-Eocene Climatic Optimum; MMCO, Mid-Miocene Climatic Optimum. Geological timescales are in million years. L-Cretaceous, Late Cretaceous; P, Pliocene; Q, Quaternary.

(B) Divergence times of Solanaceae. The mean ages of major clades are shown to the left of the corresponding nodes, with the 95% CI in square brackets. Names of six subfamilies are abbreviated: SZ, Schizanthoideae; GT, Goetzeoideae; SW, Schwenckioideae; CT, Cestroideae; PT, Petunioideae; NC, Nicotianoideae.
