Transcriptome and proteome analyses to investigate the molecular underpinnings of cold response in the Colorado potato beetle, Leptinotarsa decemlineata.

The Colorado potato beetle (Leptinotarsa decemlineata (Say)) is an insect that can cope with prolonged periods of low temperatures exposure. The molecular changes required to adapt to such conditions have not been thoroughly investigated in this insect. The current work aims at characterizing deregulated transcripts and proteins in adult L.

Characterization of cold-associated microRNAs in the freeze-tolerant gall fly Eurosta solidaginis using high-throughput sequencing.

Significant physiological and biochemical changes are observed in freeze-tolerant insects when confronted with cold temperatures. These insects have adapted to winter by retreating into a hypometabolic state of diapause and implementing cryoprotective mechanisms that allow them to survive whole body freezing. MicroRNAs (miRNAs), a family of short ribonucleic acids, are emerging as likely molecular players underlying the process of cold adaptation.
