The forkhead box genes (Fox genes) are expressed in many tissues during embryogenesis and their products play a key role in organogenesis. We cloned two Fox genes from an embryonic cDNA library of medaka (Oryzias latipes). One was MeHNF3β, a homologue of HNF3β (FoxA2). The other was Mefkhl (medaka-forkheadl), related to HNF3γ (FoxA3). We found that the expression pattern of FoxA3 differs in some aspects between medaka and zebrafish. Mefkhl is expressed in the dorsal marginal zone, embryonic shield, polster, gut and slightly axial mesoderm, whereas zebrafish FoxA3 is expressed in the yolk syncytial layer (YSL), axial mesoderm, polster, gut and posterior neural crest cells (Odenthal and Nusslein-Volhard, 1998, Dev Genes Evol 208, 245-258). In zebrafish, the level of expression of FoxA3 in the axial mesoderm is similar to that of FoxA2 (axial) ; in medaka, FoxA3 (Mefkhl} expression is mainly detected in the polster, and FoxA2 (MeHNF3β) is expressed in the axial mesoderm. This indicates that the combined functioning of FoxA2 and FoxA3 in the organogenesis of the polster and axial mesoderm differs between medaka and zebrafish.
