Transcriptome and metabolome integration reveals molecular mechanisms underlying divergent cold tolerance in geographically distinct Procambarus clarkii populations.
Low temperature is a major environmental stressor that constrains the survival and distribution of Procambarus clarkii. To explore the cold adaptation mechanisms of geographically differentiated populations, we exposed P. clarkii from Northeast China, Hubei and Anhui to continuous cold stress at 4 °C, while crayfish ma...
