摘要: Respiration, mitochondrial (mt)DNA content, and mitochondrial-specific RNA expression in fat body cells from active cold-adapted larvae of the goldenrod gall fly, Eurosta solidaginis, Arctic woolly bear caterpillar, Gynaephora groenlandica, were compared. Reduced amounts mtDNA observed both E. solidaginis G. groenlandica collected fall or winter, compared with summer-collected larvae. increased to levels similar those after incubation at 10 degrees C 15 for 5 h. Mitochondrial-specific RNAs (COI 16S) Our results suggest that proteins required respiration may be restored rapidly stable present overwintering
