Genome-wide and gene expression analyses of the hagfish olfactory receptors illuminate lineage-specific diversification of olfaction in basal vertebrates

Hirofumi Kariyayama, Yusuke Ooi, Hiromu Kashima…·Daichi G. Suzuki

This study identifies and characterizes olfactory receptor repertoires in hagfish, revealing that V2Rs originated in the vertebrate common ancestor and diversified in hagfish for adaptation to deep-sea environments.
