Topographic cladogram with additional information for PP2C protein phosphatase sequences 1 through 84. Taxon number is as shown in Figure 7. Figure characteristics are as described in legend to Figure 2. The following sequences are newly identified protein phosphatase candidates (previously annotated as putative or unknown): At2g28890, At3g09400, and At1g75010 (designated in the figure with the symbol †). The following sequences were rejected at the final alignment stage: At2g46920, At2g35350, At3g23360, At3g27140, At4g08260, At4g11040, and At1g17550.
