Bottom Line: In the organismal phylogeny from 136 housekeeping loci, Rozella diverged first from all other fungi.Indicating functional and sequence similarity, Gonapodya, like many Dikarya, can use pectin as a carbon source for growth in pure culture.This implies that 750 million years, the estimated maximum age of origin of the pectin-containing streptophytes represents a maximum age for the divergence of Chytridiomycota from the lineage including Dikarya.

Phylogeny of fungi based on analysis of data from 40 genomes. Numbers in black are the bootstrap values from ML analysis; the posterior probability from Bayesian analysis was one unless specified otherwise by a numeral following a slash. Numbers in red are the fixation points in RADICAL analysis, and smaller numbers indicate better support for the node, whereas red asterisks indicate nodes so poorly supported that they were not fixed. The sidebars show the number of genes present in each species, out of the 136 genes included in the analysis. Mucor circinelloides and Mortierella verticillata had the largest number, 126 genes each.

The sidebars show the number of genes present in each species, out of the 136 genes included in the analysis. Mucor circinelloides and Mortierella verticillata had the largest number, 126 genes each.

Mentions: The phylogenetic relationships among major fungal groups were largely consistent across different analyses in this study, with moderate to strong support (fig. 1, supplementary table S4, Supplementary Material online). The monophyly of fungi was well supported. Rozella represented the earliest split from the remaining fungi, followed by the two Blastocladiomycota taxa, Allomyces and Catenaria. Chytridiomycota formed a clade sister to predominantly terrestrial fungi consisting of zygomycota I and zygomycota II, Ascomycota, and Basidiomycota. In our dataset, out of all the 136 single-copy orthologs used in the phylogeny reconstruction, only 38 genes were found in Allomyces, 60 in Rozella, and 66 in Catenaria, whereas the other fungal species averaged 100 genes present (fig. 1). The relationships among these taxa that were missing the most data were also among the least well supported in our analyses.Fig. 1.—
