Abstract:
A small freshwater fish medaka (Oryzias latipes) has been one of the most attractive experimental systems for research in genetics and developmental biology. We have formed an international consortium Medaka Genome Initiative (MGI) to collect and share various information and resources on medaka. The MGI has set an ambitious goal aiming at the complete sequencing of the medaka genome and as a feasibility study we have begun sequencing one particular chromosome, linkage group 22 (LG22) of approximately 22 Mb in size. Initial sequence analysis revealed unique features of the medaka genome in comparison to fugu genome.
