Figure 7. Maximum parsimony tree of 34 R genes containing zinc finger proteins.

The bootstrap consensus tree (1000 replicates) is taken to represent the relationship between the taxa. Branches corresponding to partitions reproduced in less than 50% bootstrap replicates are collapsed. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) is shown next to the branches. The name of R gene, zinc finger types and crops are given on the termini of branches.
