Outline of Final Research Achievements

Recently, much more attention has paid to cephalochordate amphioxus to answer an important question of metazoan evolution, namely the origin and evolution of chordates. In order to characterize the notochord of adult amphioxus, we examined gene expression profiles by RNA-seq analysis. These genes play roles in the formation, maintenance and function of the notochord.The present repertoire of genes provide molecular basis for future evo-devo studies of early chordate evolution.
