Establishment of the dorso-ventral axis in this organism involves the secretion of BMP2B in the ventral mesoderm that is blocked by chordino secreted by the dorsal mesoderm.
Eggs of this organism can be held in the ovarian fluid of O. kisutch to facilitate delayed in-vitro fertilization. Establishment of the dorso-ventral axis in this organism involves the secretion of BMP2B in the ventral mesoderm that is blocked by chordino secreted by the dorsal mesoderm. Christiane Nusslein-Volhard, Wolfgang Driever, and Mark Fishman developed an ENU-based technique for mutagenizing this organism; thousands of mutations in developmentally active genes were recovered in those Boston/Tubingen screens, though this organism is of limited use in forward genetic screens due to a genome duplication in the teleost lineage. The Casper mutant of this organism is completely transparent, and they take on a tadpole-like form 24 hours after fertilization. For 10 points, identify this model organism, a freshwater fish, which is so named for its black and white stripes.
