title: [Comparative phylogenetic analysis of the rice and Arabidopsis PHD-finger proteins].
abstract: PHD-finger (plant homeodomain finger), a unique Cys4-His-Cys3 pattern zinc-containing domain, is widely found in many transcriptional regulation proteins from plants or animals. This protein has many different family members distributing in plant or animal proteome,and plays key roles in the development. Here, we identified 44 different putative PHD-finger proteins in the rice (Oryza sativa) genome and performed a phylogenetic analysis with 45 Arabidopsis thaliana proteins. The analysis led to a classification of the 89 proteins into two major groups based on the number of PHD-fingers. Phylogentic analysis of these proteins indicated that there are common ancestors in both plant and human genomes, from which two or three PHD-finger containing proteins might duplicate.
