Figure 3. Maximum likelihood phylogram from analysis of complete plastomes excluding gapped sites and including positively selected sites (tree X) showing relationships among major lineages of Poaceae.

Figure 3

Subfamilies are collapsed and only the branch subtending each subfamilial clade is shown. Bootstrap support is indicated along branches, according to the legend on the upper left. Two alternative topologies within the PACMAD clade, not shown in the figure, are identified in our trees: (1) Aristidoideae are sister to the rest of the PACMAD clade, with BP = 69–100%, in trees A, C, Q, W and Y; and (2) Aristidoideae and Panicoideae form a weakly supported clade (BP = 52%) in tree F that is sister to the rest of the PACMAD clade.
