Evolutionary trajectories are contingent on mitonuclear interactions

Abstract: Critical mitochondrial functions, including cellular respiration, rely on frequently interacting components expressed from both the mitochondrial and nuclear genomes. The fitness of eukaryotic organisms depends on a tight collaboration between both genomes. In the face of an elevated rate of evolution in the mitochondrial genome, current models predict that maintenance of mitonuclear compatibility relies on compensatory evolution of the nuclear genome. Mitonuclear interactions would therefore exert a strong in… Show more

“…As the mitochondrial genome is typically uniparentally inherited and mutates at a faster rate than the nuclear genome across many species, it is thus predicted that the recombining nuclear genome will be able to respond adaptively to its fast-changing mitochondrial counterpart (Barreto et al 2018; Healy & Burton 2020; Hill 2020). This process has been shown to result in tight mitonuclear coevolution in some taxa, which has the potential to lead to rapid divergence between populations in their mitonuclear genotypes (Morales et al 2018; Wang et al 2021;Burton 2022;Biot-Pelletier et al 2023). This process poses a challenge in the event of admixture between disjunct populations with unique trajectories of mitonuclear coevolution, as they may generate genomic incompatibilities.…”
