Outline of Final Research Achievements

The aim of this research project is to understand the control mechanism of innate vocalization at multi-level by using rooster crowing "Cock-a-doodle-doo" as a model. At group level, we revealed that crowing is controlled by the circadian clock and social rank in the Red jungle fowls, ancestral species of chicken. At gene expression level, we performed RNA-seq was using the intracerebral centers of individual showing and not showing crowing, and analyzed it using informatics to extract candidate genes that control motivation of vocalization. At genome level, in order to clarify the molecular basis that regulates the pattern of vocalization, we recorded crowing from various chickens showing normal or unique vocalization and also collected blood for extracting DNA.
