Fungal Pathogen sheds gene silencing machinery to become more dangerous

A potentially deadly fungus called Cryptococcus deuterogatti tossed aside over a dozen different genes on its way to becoming a new, more virulent species. Duke researchers have found that most of the discarded genes play a part in RNA interference or RNAi, a defense mechanism employed by fungi and other organisms to protect the integrity of their genomes. The study was published March 4 in PLOS Genetics.
