Impaired feeding in snap29 mutants
(A) Lateral views of 6 dpf larvae in which guts are indicated by an arrow. Larvae were fed
Rhodamine Dextran-containing food that allow detecting the presence of food in the gut.
The gut of a snap29K164* mutant animal appears as empty as that of unfed wild type
larvae, when compared to fed ones. (B) Ventral views of the splanchnocranium of 5 dpf
larvae. Cartilage staining with Alcian Blue did not highlight any difference in organization
and/or differentiation between wild type and snap29K164* mutants. m: Meckel’s cartilages,
ch: ceratohyal, pq: palatoquadrate, cbs: ceratobranchials.
