Abstract

A long-standing question about the early evolution of club fungi (phylum Basidiomycota) is the relationship between the three major groups, Pucciniomycotina, Ustilaginomycotina and Agaricomycotina. It is unresolved whether Agaricomycotina are more closely related to Ustilaginomycotina or to Pucciniomycotina. Here we reconstructed the branching order of the three subphyla through two sources of phylogenetic signals, i.e. standard phylogenomic analysis and alignment-free phylogenetic approach. Overall, beyond congruency within the frame of standard phylogenomic analysis, our results consistently and robustly supported the early divergence of Ustilaginomycotina and a closer relationship between Agaricomycotina and Pucciniomycotina.

Figures

Fig. 1
Fig. 1
The most likely evolutionary relationship involving the three subphyla of Basidiomycota. The tree shows higher-than-order level relationships of the majority rule consensus of 4 standard phylogenomic reconstructions of 91 genomes using 171 gene clusters. Statistical supports are numbers attached to nodes: from left to right, BP of ML, BP of MP, PP of Bayes and BP of NJ. Bootstrap values are reported as percentages. “*” indicates BP = 100% or PP = 1. “-” indicates the node is not recovered by corresponding tree reconstruction method.

Fig. 2
The inferred CVTree of the 91 fungi genomes. This tree is obtained using whole-gene repertoires of these genomes with K = 7. Bootstrap values are reported as percentages. “*” indicates BP = 100%. Only higher-than-order level relationships are shown here. See Fig. S14 for the full CVTree.
