Phylogenetic tree and domain composition of JMJD6 and KDM5 proteins. Bayesian phylogenetic tree of JMJD6 (A) and KDM5 (B) predicted proteins from Arabidopsis thaliana (At), Oryza sativa (Os), Solanum lycopersicon (Sl) and Zea mays (Zm). Bootstrap values higher than 50% are shown. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. N-terminal F-box (PF00646), and C-terminal JmjC are conserved domains of JMJD6s demethylases; JmjN, BRIGHT/ARID (PF01388), two PHD (PF00628), JmjC, and C5HC2 are conserved domains of the subgroup I of KDM5; JmjN, JmJC, C5HC2, FYRN (PF05964) and FYRC (PF05965) are conserved domains of the subgroup II of class KDM5.
