| Research Abstract |
To detect candidate genes that caused adaptive divergence in natural populations, a screening method of comprehensive gene expression divergence for the non-model species was investigated using the anadromous goby Leucopsarion petersii as a model system. Limited transcriptome profiles obtained by an AFLP-based gene expression profiling method called"high coverage expression profiling(HiCEP)"were compared between the Japan Sea and Pacific Ocean populations of this species. Some genes showed striking and stable expression differences between these populations. Thus, this study clarified that HiCEP is a useful method for exploring gene expression divergence in the nonmode l species whose genomic information is not available.
