Research Overview

Human beings have obtained food by domesticating wild plants. Finding out how the crops grown have advanced throughout the history of cultivation can provide us with important guidelines for the development of new crop strains that will deliver increased yields in future. I am working to elucidate the origins of the cultivars of Brassicaceae ,which include many important food crops-daikon radishes in particular-as well as the evolutionary mechanisms by which the varieties grown in Japan have developed. In the process, I have proven that cultivated daikon radishes have polyphyletic origins, and I received the Award of Japanese Society of Breeding in 2006 for this work. I am currently researching the genetic origins of sugukina turnip (Brassica rapa ), a specialty of Kamigamo, Kyoto.
I also want to develop crops with new properties through organellar genome engineering techniques such as cell fusion and gene replacement. In particular, I have created the world's first somatic hybrids between cabbages and Arabidopsis thaliana , the first higher plant to have its genome completely decoded. This work provides useful material for the development of vegetable varieties belonging to the Brassicaceae family. Further, I am expanding the application of chloroplast recombinant DNA technology, which has been developed primarily for tobacco, and we have successfully introduced recombinant chloroplasts into petunia.
