Phylogenetic tree and intron map of BX1, IGL, TSA and TSA_like sequences in Poaceae. Maximum likelihood tree with branch lengths drawn in scale in terms of the number of substitutions per site. Nodes with dots indicate duplication events. The locations of phase 0 introns (|) and phase 1 introns ([) are based on their relative place on the protein alignment and are numbered from 1 to 8. The intron map is not to scale. Only nodes with bootstrap values superior to 75% are shown. Two TSA and two indole synthase sequences of A. thaliana and Arabidopsis lyrata are closely related but are non-Poaceae sequences. Sequences were named according to their closest homolog in maize and IGL numbers were arbitrarily attributed.
