Japanese quail (Coturnix japonica) are a popular domestic poultry species raised for meat and eggs in Asia and Europe. Quail have been used for genetics research since 19401, and are an increasingly important model species for developmental biology and biomedical research2,3, including the fields of neuroscience, reproductive biology and immunology.
Japanese quail have a rapid growth rate and a short life cycle, becoming sexually mature only 8 weeks after hatch. Due to this and their rapid and reliable reproductive response to changes in photoperiod, Japanese quail have been used for decades as a model species to elucidate the molecular and neurological mechanisms that regulate avian seasonal biology4–7. Japanese quail have also been used to study the genetic and neuroendocrine mechanisms underlying reproductive behaviours, including maternal care and sexual behaviours8,9. In addition, Japanese quail are a useful species to investigate the effects of early life stress10, the genetic basis of emotional reactivity and social reinstatement11–13, and have improved our understanding of the control and spread of infectious diseases14,15, including avian influenza16–18.
The quail embryo is a popular model for developmental biology as it is robust to manipulation, facilitating fate mapping studies19 and dynamic imaging of embryogenesis20. Quail have been used as a model for stem cell differentiation2, and a culture system that mimics the development of hematopoietic stem cells has been developed in quail21.
Recently, a high-quality annotated genome of the Japanese quail has been assembled and annotated by researchers at the Roslin Institute3.
