Expansion of effector candidate families in S . sclerotiorum genome. (a) Composition of clusters determined by Markov clustering of S. sclerotiorum and B. cinerea complete proteomes (MCL clusters) containing putative duplicated S. sclerotiorum SPEP genes. (b) Distribution of distances to the closest repetitive genomic element on 5’ and 3’ side for all genes (heatmap) and the genes encoding the 29 SPEPs in MCL clusters (dots). (c) Parsimony phylogenetic tree of SS1G_13371 SPEP and its 19 closest homologs. Bootstrap support calculated over 100 replicates is shown for the major branches, S. sclerotiorum clade is shown in red.
