Plasticity in cryoprotectant synthesis involves coordinated shunting away from pyruvate production.

The article discusses the plasticity in cryoprotectant synthesis in insects, specifically focusing on glycerol production in response to cold temperatures. Insects in temperate regions accumulate glycerol to avoid freezing, with some species showing a rapid increase in glycerol production during sudden cold events. The study found evidence of increased enzyme activity and mRNA abundance related to glycolysis in response to cold exposure, with northern populations producing more glycerol upon cold shock. This research provides insight into the mechanisms behind the plasticity of cold hardiness in insects. [Extracted from the article]
