  1. Expression domains with a high expression level were shown as '++', while '+' denotes a low expression signal. '-' indicates no expression signal detected and 'N.I.' indicates a case in which the expression pattern was not investigated. Additional spatial and temporal details of gene expression are shown in brackets. Abbreviations: di = diencephalon; cf = caudal fin; df = dorsal fin; af = anal fin; pf = pectoral fin; csm = circular smooth muscles of pharynx; olf = olfactory placode; ov = otic vesicle. aSome of these expression domains are shown in Additional file 5 and Additional file 6, respectively.
