Figure 4

The species phylogeny shows four clades, the group of Nicotiana species, the clade of Datura, the group of Capsicum species and the Solanum group. Petunia inflata was selected as the outgroup species. P. inflata diverged from all the Solanaceae species studied here approximately 35 Mya. Nicotiana species diverged almost 32 Mya. While Datura stramonium diverged ~ 30.1 Mya from Solanum, Capsicum and Nicotiana species. The rate of gene gain and lost (λ) resulted from CAFE analysis was 0.0153461 for the whole tree. The terminal branch with the most rapidly significant evolving gene families is the one leading to D. stramonium clade. The internal branch with the largest numbers of significant contractions corresponds also to the most recent common ancestor of Datura species clade. The terminal branches with the most contractions are the one leading to D. stramonium Teotihuacán. While D. stramonium Ticumán showed the highest number of gene family expansions.
