The effect of changing sampling of monocots as a function ofphylogenetic method. Analysis of the 61-gene data matrix using: Rows A-C, DNA parsimony; D-F, protein parsimony; G-I DNA ML HKY85 with no rate categories; J-L, RY-coded DNA parsimony. The first column of trees is with the Goremykin et al. [19] taxon sampling (grasses, but not Acorus), the second is with Acorus but not grasses, and the third is with both grasses and Acorus. All analyses used the first- and second-position matrix, either with or without the addition of Acorus as explained in Methods. Trees J-L use the same matrices, but with the nucleotides RY-coded.
