Fig 2. Divergence time estimations for PIF genes.

Fig 2

The divergence times between the duplicated PIF genes in Solanaceae are shown in green. The divergence times between tomatoes (S. lycopersicum and S. pennellii) and S. tuberosum and, S. lycopersicum and S. pennellii homologs are indicated in blue and red, respectively. Species divergence times are shown in black (Arabidopsis thaliana-Solanaceae [34], Solanum tuberosum- Solanum lycopersicum [30], S. pennelli-S. lycopersicum [27]). Values are expressed in million years ago.
