In crustaceans, G protein-coupled receptors (GPCRs) are the largest transmembrane receptor family and function by mediating various environmental stimuli in cells. Understanding GPCR signaling is crucial to better understanding of crustacean endocrinology. GPCRs evolved from early eukaryotes, and genome-wide identification of GPCRs in a particular taxon can provide insight into evolutionary tendencies and adaptive strategies of GPCR response to environmental stimuli. Here, we identified 194 full-length GPCR genes in the water flea Daphnia magna that can be divided into five distinct classes (A, B, C, F, and other). A strong orthologous relationship for amine, neuropeptide, and opsin receptors was found in the phylogenetic comparison of D. magna GPCRs to those of humans and two well-known insects (Drosophila melanogaster and Solenopsis invicta). Our results based on phylogenetic relationships suggest that most GPCRs subfamilies have undergone sporadic evolutionary processes for adaptation to environmental pressures. Despite the dynamics of GPCR evolution, some GPCRs are highly conserved between species. This study provides a better understanding of the evolution of GPCRs and expands our knowledge of the potential physiological mechanisms in D. magna in response to various environmental stimuli.
