Population Genomics of an Obligately Halophilic Basidiomycete Wallemia ichthyophaga

Based on the comparison of <i>W. ichthyophaga</i> genomes it appears that some phylogenetic lineages of the species can persist in the same location over at least several years. Apart from this, the differences between the strains do not reflect the isolation habitat or geographic location. Together with results supporting the existence of (sexual) recombination in <i>W. ichthyophaga</i>, the presented results indicate that strains of <i>W. ichthyophaga</i> can form a single recombining population even between different habitats and over large geographical distances.
