In the Chytridiomycota, Batrachochytrium dendrobatidis and Salamandrachytrium terminator are the only known members that parasitize vertebrate hosts. In this project we will investigate how these two fungi adapted to the vertebrate host. Therefore, we will conduct comparative transcriptomics and genomics on the novel chytrid species S. terminator, B. dendrobatidis and a selection of other members of the Chytridiomycota living in water and soil.
