Paternally Expressed Imprinted Genes under Positive Darwinian Selection in Arabidopsis thaliana.
In this paper in MBE we examined the selective pressure variation across genomically imprinted genes in the inbreeding species Arabidopsis thaliana. Genomic imprinting is an epigenetic phenomenon where autosomal genes display uniparental expression depending on whether they are maternally or paternally inherited. Genomic imprinting can arise from parental conflicts over resource allocation to the offspring, which…
