Genomic Evidence of Recombination in the Basidiomycete Wallemia mellicola.

ABSTRACT: One of the most commonly encountered species in the small basidiomycetous sub-phylum Wallemiomycotina is Wallemiamellicola, a xerotolerant fungus with a widespread distribution. To investigate the population characteristics of the species, whole genomes of twenty-five strains were sequenced. Apart from identification of four strains of clonal origin, the distances between the genomes failed to reflect either the isolation habitat of the strains or their geographical origin. Strains from different parts of the world appeared to represent a relatively homogenous and widespread population. The lack of concordance between individual gene phylogenies and the decay of linkage disequilibrium indicated that W. mellicola is at least occasionally recombining. Two versions of a p
