Phylogenetic tree and domain composition of KDM3 proteins. Bayesian phylogenetic tree of KDM3 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. RING-finger (IPR001841) and JmjC are conserved domains of KDM3 demethylases.
