Concordant divergence of mitogenomes and a mitonuclear gene cluster in bird lineages inhabiting different climates [Nature Ecology & Evolution]

par Frédéric Magné - publié le

Metabolic processes in eukaryotic cells depend on interactions between mitochondrial and nuclear gene products (mitonuclear interactions). These interactions could have a direct role in population divergence. Here, we study mitonuclear co-evolution in a widespread bird that experienced population divergence followed by bidirectional mitochondrial introgression into different nuclear backgrounds. Using >60,000 single nucleotide polymorphisms, we quantify patterns of nuclear genetic differentiation between populations that occupy areas with different climates and harbour deeply divergent mitochondrial lineages despite ongoing nuclear gene flow.(...)
