Maximum likelihood phylogenetic trees of the MHXs. The trees were generated by MEGA5[45], after alignment of the sequences, as detailed in the Methods. A. An unrooted bootstrap consensus tree of angiosperm MHXs inferred from 1000 replicates of the analysis. B. A rooted bootstrap consensus tree of plant MHXs. The percentage of replicate trees in which the associated proteins clustered together in the bootstrap test (1000 replicates) are shown next to the branches. Bootstrap values lower than 60% are not shown. The proteins were classified by the phylogenetic groups of their source organisms.
