Long-Term Cold Acclimation Extends Survival Time at 0 degrees C and Modifies the Metabolomic Profiles of the Larvae of the Fruit Fly Drosophila melanogaster
Original language description
Background: Drosophila melanogaster is a chill-susceptible insect. Previous studies on this fly focused on acute direct chilling injury during cold shock and showed that lower lethal temperature (LLT, approximately -5 degrees C) exhibits relatively low plasticity and that acclimations, both rapid cold hardening (RCH) and long-term cold acclimation, shift the LLT by only a few degrees at the maximum. Principal Findings: We found that long-term cold acclimation considerably improved cold tolerance in fully grown third-instar larvae of D. melanogaster. A comparison of the larvae acclimated at constant 25 degrees C with those acclimated at constant 15 degrees C followed by constant 6 degrees C for 2 d (15 degrees C -} 6 degrees C) showed that long-term cold acclimation extended the lethal time for 50% of the population (Lt(50)) during exposure to constant 0 degrees C as much as 630-fold (from 0.137 h to 86.658 h). Such marked physiological plasticity in Lt(50) (in contrast to LLT) suggeste
