Expression pattern of the Sox31 gene during zebrafish embryonic development

We have identified a novel Sox gene in zebrafish (Danio rerio), Sox31, closely related to mammalian group B Sox genes. The gene is maternally expressed. Zygotic transcription starts at gastrulation, in the presumptive neuroectoderm. Later, expression is restricted to the developing central nervous system, including forebrain, midbrain, hindbrain and spinal cord.
