Phylogram of the four TOM20 proteins from Arabidopsis and TOM20 from potato and tomato. An alignment was calculated with ClustalW. The phylogenetic analysis was performed using the programs Seqboot, Protdist, Neighbor, Consensus, and Drawgramm of the Phylip program package. The scale bar in the left bottom corner indicates a bootstrap value of 10. The TOM20 sequence from tomato was deduced from the EST clone AI486270.
