DNA data is beginning to reveal just how fungi can live and thrive in marine environments. The sea ain’t Kansas, and species such as Debaryomyces Hansenii (Hooley 2006) had to develop specialized abilities for life in an aquatic Oz. Compared to its relatives from terrestrial and airbone environments, D. Hanseii has a genome of similar size but greatly expanded in gene content—a diverse genomic armory that likely helps it to cope with the physiological challenges of a saline environment.
