Microbial Ecology
Reproductive isolation is central to the maintenance of species, and especially in sympatry, effective barriers to prevent interspecific crosses are expected. Host specificity is thought to constitute an effective mechanism for the formation of barriers in different genera of Fungi, but evidence for endophytes is so far lacking. Sexual Epichloë species (Ascomycota, Clavicipitaceae) represent an ideal study system to investigate the mechanisms underlying speciation as mediated by host specificity because they include species complexes with several host-specific taxa. Here, we studied genetic differentiation of three host-specific Epichloë species using microsatellite markers that were newly in silico identified on the genome of Epichloë poae. Among these, 15 were experimentally tested and applied to study an extensive sampling of isolates representing Epichloë typhina infecting Dactylis glomerata and Epichloë clarkii infecting Holcus lanatus from a site with sympatric populations in Switzerland, as well as a reduced sampling of E. poae infecting Poa nemoralis to create a three-taxon dataset. Both principal coordinate analysis and Bayesian clustering algorithm showed three genetically distinct groups representing the three host-specific species. High pairwise F ST values among the three species, as well as sequencing data of the tefA gene revealing diagnostic single nucleotide polymorphisms (SNPs), further support the hypothesis of genetic discontinuities among the taxa. These results provide genotypic evidence of the maintenance of reproductive isolation of the species in a context of sympatry. In silico testing of 885 discovered microsatellites on the genome of Epichloë festucae extend their applicability to a wider taxonomic range of Epichloë.
