Transcriptome of larvae Songpu mirror carp and Barbless carp

Songpu mirror carp and Barbless carp are two closely related species of the carp family and they can hybrid to generate the offspring. In addition, Songpu mirror carp exhibited stronger abilities of cold tolerance and acclimation than Barbless carp;then, we compared transcriptomic profiles of two carp species to identify key signaling factors and pathways for cold tolerance and acclimation.
