Limited directional selection but coevolutionary signals among imprinted genes in <i>A. lyrata</i>.

ABSTRACT: Genomic imprinting is a form of gene regulation leading to the unequal expression of maternal and paternal alleles. The main hypothesis invoked to explain the evolution of imprinted genes is the kinship theory, which posits a conflict between parental genomes over resource allocation in progeny. According to this theory, imprinted genes are expected to undergo a shift from balancing to directional selection, in coding or regulatory regions. However, most studies addressing selection in imprinted genes have focused on self-fertilizing species, where conflicts over resource allocation are predicted to be weak. Consequently, the impact of kinship theory on the evolution of imprinted genes remains largely untested. Furthermore, the predicted coevolution between certain imprinted genes under ki
