Experimental evidence for negative selection in the evolution of a Yersinia pestis pseudogene.

Proceedings of the National Academy of Sciences of the United States of America - 10 Jun 2008

Sun Yi-Cheng, Hinnebusch B Joseph, Darby Creg

Abstract excerpt

Yersinia pestis, the agent of bubonic plague, evolved from the enteric pathogen Yersinia pseudotuberculosis within the past 20,000 years. Because ancestor and descendant both exist, it is possible to infer steps in molecular evolution by direct experimental approaches. The Y. pestis life cycle in...
