Phylogenetic Tree of FtsH Proteins from Arabidopsis and Other Organisms.

The tree was constructed using the N-J method (Saitou and Nei, 1987). The bootstrap values based on 1000 replications are indicated together with the branches. Chloroplastic and mitochondrial Arabidopsis proteins whose locations were determined by the GFP transient assay (see Figure 2) are indicated in green and red, respectively. The nomenclature of Arabidopsis FtsH proteins is according to Sokolenko et al. (2002). Arabidopsis Genome Initiative numbers of FtsHs are as follows: FtsH1, At1g50250; FtsH3, At2g29080; FtsH4, At2g6140; FtsH6, At5g15250; FtsH7, At3g47060; FtsH8, At1g06430; FtsH9, At5g58870; FtsH10, At1g07510; FtsH11, At5g53170; and FtsH12, At1g79560.
