Variations in mitochondrial DNA and gene transcription in freezing‐tolerant larvae of Eurosta solidaginis (Diptera: Tephritidae) and Gynaephora groenlandica (Lepidoptera: Lymantriidae)
Abstract Respiration, mitochondrial (mt)DNA content, and mitochondrial‐specific RNA expression in fat body cells from active and cold‐adapted larvae of the goldenrod gall fly, Eurosta solidaginis , and the Arctic woolly bear caterpillar, Gynaephora groenlandica , were compared. Reduced amounts of mt...
