Neighbour-joining (NJ) tree based on Kimura two-parameter distances of 11 Festuca, one Aira praecox and three Poa PgiC exon sequences (1182 bp), using Bromus sterilis as outgroup. Sequences from PgiC1 and PgiC2 of F. ovina are circled with dotted lines. Nodal support is given by bootstrap values based on 10 000 replications (neighbour-joining/maximum parsimony).
