Identification of Cochlioquinone 9 through FNSII Knock-out and Breeding of Functional Rice

Rice has long been used as a staple food all over the world. Rice improvement has been started since the 1970s, and the focus was on increasing the yield. However, after increasing the quantity to some extent, people have been trying to breed rice varieties that taste good and add functionality. Anthocyanins act as antioxidants and are substances that can prevent various diseases. Therefore, in this study, FNSII was knocked-out by using genetic scissors, and the presence of genome editing and the phenotype of regenerated plants were confirmed.
