We have identified a novel Sox gene in zebrafish (Danio rerio), Sox31, clos
ely related to mammalian group B Sox genes. The gene is maternally expresse
d. Zygotic transcription starts at gastrulation, in the presumptive neuroec
toderm. Later, expression is restricted to the developing central nervous s
ystem, including forebrain, midbrain, hindbrain and spinal cord. (C) 2001 E
