Zebrafish foxi one modulates cellular responses to Fgf signaling required for the integrity of ear and jaw patterning.

Abstract excerpt

We identified four insertional alleles of foxi one (foo), an embryonic lethal mutation in zebrafish that displays defects in both otic placode and the jaw. In foo/foo embryos the otic placode is split into two smaller placodes and mutant embryos show a dorsoventral (DV) cartilage defect manifested as a reduced hyomandibular and reduced third and fourth branchial arches. We identified foxi one (foo), the zebrafish...
