Mutations in chrysanthemum have been successfully introduced by gene editing technology. This is the first report in the world of genome editing in a higher polyploid plant, chrysanthemum which has been difficult due to its large genome with very little information available so far. Researchers from the Institute of Vegetable and Floriculture Science, NARO have succeeded in obtaining a chrysanthemum with mutation in yellowish-green fluorescent protein gene inducing reduction in fluorescence by editing the genome of a transgenic chrysanthemum expressing the fluorescent gene and generating axillary bud derived plants. The genome editing technology is expected to become a promising method in improvement and breeding of chrysanthemum cultivars.
