Genes Coding for GPI Biosynthesis in Pneumocystis Experienced Relaxed Selection: A Follow-up Study

Luis Delaye
Received: May 5, 2019; Published: July 11, 2019; doi:10.21926/obm.genet.1903083

Abstract: Background: Phylogenetic analyses shows that Pneumocystis species have coevolved with their mammalian hosts for millions of years. As a result, infection by Pneumocystis is species specific (i.e. a given Pneumocystis species can infect only a single species of host). This specificity suggests the ex [...]
