Research Summary

Norio  Kato(D.Agr.) Minami Matsui

Conventional and genetic modification-based breeding methods have been used to improve crops. However, it is becoming increasingly difficult to meet the growing demand for food and biomass for various reasons including population increase and climate change. Therefore innovation in the area of plant breeding is more important than ever before. We have succeeded in developing an innovative platform technology that enables selectable marker-free genome editing using zygotes in rice. In this coming two years, we aim to apply this technology to other agronomically important species including wheat and corn, and establish it as a fundamental technology for next generation breeding.
