Abstract

The results of transcriptome analysis of liver tissues of juvenile clariid catfish Clarias gariepinus to identify genes involved in acclimation to low temperatures are presented. A total of 377 differentially expressed genes (DEGs) involved in the activation of ubiquitin-dependent processes of protein catabolism, lipid metabolism, immune response, signaling pathways, etc., are found. Low water temperature suppresses the basal metabolism of juvenile C. gariepinus and induces cold stress. At the same time, the adaptive potential to cold resistance is traced in the denaturation of damaged proteins, complex metabolic reconfiguration in liver tissues, and the expression of highly mobile group genes.
