Interpretive Summary:

Technical Abstract: The Zygomycete lineages mark the major transition from zoosporic life histories of the common ancestors of Fungi and the earliest diverging chytrid lineages (Chytridiomycota and Blastocladiomycota). Genome comparisons from these lineages may reveal gene content changes that reflect the transition to nonflagellated, filamentous, and multicellular Dikarya (i.e., Ascomycota and Basidiomycota). The zygomycete lineages have been classified at times as a single monophyletic group and also split into an unresolved paraphyly. Phylogenomic analyses provide substantial support for two monophyletic clades one containing Entomophtheromycota, Kickxellomycotina, and Zoopagomycotina (EKZ) and the other comprising Mortierellomycotina, Mucoromycotina, and Glomeromycota (MMG). Comparison of gene content among the species and their outgroups identified zygomycetespecific genes and confirmations of gene losses and gains that correspond to the transition from a zoosporic ancestor to primarily filamentous or yeast growth forms. Genome sequences from more than 35 zygomycetes were used to evaluate the phylogenetic position of these lineages, and compare gene content and phylogenetic relationships among thousands of groups of orthologous genes with animal and zoosporic fungal outgroups and the Dikarya fungi. The Zygomycete Genealogy of Life project is building a phylogenomic framework to address genomic and morphological evolution, broad genome and transcriptome sampling of zygomycete lineages including hostassociated species, incorporating fossilbased dating, bioimaging, and improved descriptions of these fungi in the Encyclopedia of Life.
