Fruit color is an important horticultural trait, which greatly affects consumer preferences. Recently, Horticulture Research published a research paper (Advance Access) entitled “Recoloring tomato fruit by CRISPR/Cas9-mediated multiplex gene editing” by Li Chuanyou Research Group from the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences. 

In this study, a strategy of using multiple gene editing technology to create seven tomato materials with different fruit colors rapidly and synchronously was proposed. Compared to traditional cross-breeding, this strategy requires less time and can obtain transgene-free plants with different colored fruits in less than one year. Most importantly, it does not alter other important agronomic traits like yield and fruit quality. This strategy has great practical potential for tomato breeding and serves as a reference for improving multigene-controlled traits of horticultural crops.
