Phylogenetic analysis of glucose-6-phosphatase encoding genes in vertebrates. Phylogenetic analyses were performed using MEGA package version 6 software [48], as previously described [49]. The phylogenetic tree was built by the neighbor-joining (NJ) method. The reliability of the inferred tree was estimated by the bootstrap method with 1000 replications. Mammalian and teleosts g6pc3 protein sequences were used to root the tree. All accession numbers (from Ensembl, or Genoscope databases) are specified in parentheses. Sarcopterygii species are written in orange and Actinopterygii species in green
