Abstract
Divergence of mating system plays an important role in speciation of fungi. Ectomycorrhizal fungi, however, pose a challenge for the study of reproductive biology because many of these fungi cannot easily be cultured and mated under laboratory conditions. To overcome these barriers, we sequenced the draft genomes of the ectomycorrhizal sister species Rhizopogon vinicolor Smith and Zeller and R. vesiculosus Smith and Zeller (Basidiomycota, Boletales) and characterized gene content and organization surrounding the homeodomain transcription factor genes of the mating type A-locus as well as the pheromone receptor and pheromone precursor genes of the mating type B-locus. These genomes are among the first available for Basidiomycota truffles. Both species possess a pair of homeodomain transcription factor homologs at the A-locus as well as pheromone receptor and pheromone precursor homologs at the B-locus. While these species possess limited divergence at the A-locus, R. vinicolor possesses a more diverse set of pheromone receptor and pheromone precursor homologs at the B-locus and R. vesiculosus has lost some B-locus homologs.. Comparison of Rhizopogon genomes with genomes from Boletales, Agaricales, and Polyporales revealed broad synteny of the A-locus region within Boletales, but several genomic rearrangements across orders. Our findings suggest a correlation between genetic diversity at the B-locus region and mating type in Boletales with tetrapolar species possessing more diverse gene content than bipolar species. Examination of dikaryotic single nucleotide polymorphisms revealed a greater degree of heterozygosity in R. vinicolor, consistent with higher genetic diversity of the B-locus and increased rates of outcrossing.
