The genome of the xerotolerant mold Wallemia sebi reveals adaptations to osmotic stress and suggests cryptic sexual reproduction

► The genome of a xerophilic fungus Wallemia sebi was sequenced and found to be 9.8 Mb. ► Phylogenomics and ultrastructure show that Wallemia belongs in Agaricomycotina. ► 93 putative osmotic stress proteins are identified. ► The High Osmolarity Glycerol pathway is found to be mostly conserved. ► Meiosis is not found during conidiogenesis but mating-type homologs are identified.
