Bayesian phylogenetic tree based on the GBSSI sequences. Branches found in both Bayesian and maximum parsimony (MP) 85% majority-rule consensus trees are indicated by bold lines. Thinopyrum intermedium sequences are in bold. Clone designations refer to individual plants analysed (numerical identifiers) and individual clones of each plant (letters). After each clone identifier, the number of identical clones and the total number of clones sequenced for that accession is given in parentheses, see also Table 2. The numbers above and below branches are Bayesian posterior probabilities and bootstrap values for MP, respectively.
