Phylogenies of anther-smut fungi and their mating-type loci linkage. Microbotryomycete phylogenetic tree based on 780 orthologous genes, including the studied Microbotryum species (shown in the anthers of their host plants) and the outgroup Rhodotorula babjevae. The empty circles indicate full bootstrap support. Tree internode certainty with no conflict bipartitions (the normalized frequency of the most frequent bipartition across gene genealogies relative to the summed frequencies of the two most frequent bipartitions) is given above the branches, indicating good support for the bipartitions. Black bars at right indicate unlinked mating-type loci, dark gray linkage of mating-type loci to centromeres, and light gray mating-type loci linkage.
