Phylogenetic reconstruction of PR-1 proteins in Moniliophthora and heatmap of expression Z-scores of PR-1. Phylogenetic relationships of PR-1 proteins from 18 M. perniciosa and 4 M. roreri isolates were inferred by maximum likelihood and branch support was obtained using 1000 bootstraps. The PRY1 protein of Saccharomyces cerevisiae was used as an outgroup. Clades filled with pink color indicate PR-1 families with evidence of positive selection detected with the site model test of CodeML. A version of this tree with non-collapsed branches can be found in Additional file 4. For each PR-1 family, the Z-score of log transformed expression levels of MpPR-1 and MrPR-1 from transcriptomic data was calculated for conditions (columns) and plotted as a heatmap. The heatmap includes MpPR-1 data from seven conditions of the C-biotype of M. perniciosa from the Witches’ Broom Transcriptomic Atlas, seven different time points of S-biotype infection in MicroTom tomato plants, and two conditions of M. roreri infection in cacao pods (frosty pod rot). Conditions highlighted with a grey background and asterisk indicate the biotrophic stage of the plant-pathogen interaction
