摘要: The role of mitochondrial DNA for the evolution life-history traits remains debated. We examined mitonuclear effects on activity multisubunit complex electron transport chain (ETC) involved in oxidative phosphorylation (OXPHOS) across lines seed beetle Acanthoscelides obtectus selected a short (E) or long (L) life more than >160 generations. constructed and phenotyped introgression lines, which allowed us to assess independent evolutionary history nuclear genome. genome was responsible largest share divergence seen ageing. However, also had sizeable effects, were sex-specific expressed primarily as epistatic interactions with disruption largely consistent coadaptation. Variation ETC explained large proportion variance ageing this multivariate relationship differed somewhat between sexes. In conclusion, epistasis has played an important laboratory activity, ageing, histories these are closely associated. architecture evolved differences bioenergetics sex-specific.
