Myo-inositol as a main metabolite in overwintering flies: seasonal metabolomic profiles and cold stress tolerance in a northern drosophilid fly

Popis výsledku v původním jazyce

Here we report the first seasonal metabolite analysis in a Drosophila species. We traced changes in the cold tolerance and metabolomic profiles in adult D. montana flies that were exposed to thermo- and photoperiods corresponding to changes in environmental conditions of their natural habitat in northern Finland. The cold tolerance of diapausing flies increased noticeably towards the onset of winter; their chill coma recovery times showed seasonal minimum between late autumn and early spring, while their survival after cold exposure remained high until late spring. The flies moderately accumulated glucose, trehalose and proline already in autumn, but the single largest change occurred in myo-inositol concentrations. This increased up to 400-fold duringthe winter and peaked at 147 nmoles per mg of fresh mass, which is among the largest accumulations of this compound reported in insects.
