Maternal-Fetal Conflict: Rapidly Evolving Proteins in the Rodent Placenta
1 Feb 2010
Abstract excerpt
Conflicting evolutionary interests between mother and offspring are hypothesized to drive an evolutionary arms race during mammalian pregnancy, and thus, positive selection may cause the rapid divergence of placental proteins that affect maternal or fetal fitness. We investigated the genomic consequences of placental expression in rodents and report that a substantial proportion (20.5%) of genes specifically...
