Abstract: Histone deacetylases (HDACs) are involved in multiple developmental processes, but their functions in the development of mechanosensory organs are largely unknown. In the present study, we report the presence of HDAC3 in the zebrafish posterior lateral line primordium and newly deposited neuromasts. We used morpholinos to show that HDAC3 knockdown severely disrupts the development of the posterior lateral line and reduces the numbers of neuromasts and sensory hair cells within these organs. In HDAC3 morphants, we also observed decreased cell pr...
