Phylogenetic tree of Poa CDO504 sequences. Maximum clade credibility tree made using BEAST [91]: 10,000,000 generations, constant population size, GTR+G model with starting substitution matrix and gamma parameter values chosen in ModelTest 3.7. Nodal support values shown are posterior probabilities/maximum parsimony bootstrap percentages (500 replicates). Only nodes with posterior probabilities ≥0.95 or bootstrap percentages ≥80 are shown. Well-supported nodes are also shown with thick lines. Representative sequences from the native Australian species from this study are shaded in grey. Other sequences are from Patterson et al. [21], downloaded from GenBank, including Phalaris used as an outgroup. All Australian copy A sequences from this study fit clade A (also called A in Patterson et al. 2005); all Australian copy B sequences fit clade B (called Clade C in Patterson et al. 2005).
