Only skin deep: shared genetic response to the deadly chytrid fungus in susceptible frog species.

Amphibian populations around the world are threatened by an emerging infectious pathogen, the chytrid fungus Batrachochytrium dendrobatidis (Bd). How can a fungal skin infection kill such a broad range of amphibian hosts? And do different host species have a similar response to Bd infection? Here, we use a genomics approach to understand the genetic response of multiple susceptible frog species to Bd infection. We characterize the transcriptomes of two closely related endangered frog species (Rana muscosa and Rana sierrae) and analyse whole genome expression profiles from frogs in controlled Bd infection experiments.
