Outline of Final Research Achievements

The fu-2 is a spontaneous and recessive medaka mutant, which exhibits fused centra and the absence of the intervertebral ligaments. As a result of positional cloning analysis, the fu-2 locus was mapped to chromosome23, but it was not identified in the medaka ensemble database. This result indicates that the fu-2 locus is locating on unknown region of choromosomal end. Finally, two candidate genes for the fu-2 phenotype, which relate to the Wnt signaling pathway, were found in this unknown region.
