Suntory officials said researchers extracted the gene that produces blue pigment in pansies and activated it inside the roses.
There are already “bluish” roses on the market, but these flowers were created through crossbreeding and cannot be called true blue, according to Suntory. The gene of the enzyme that produces the blue pigment, delphinidin, is not found in rose petals to begin with.
Thanks to biotechnology, the petals of Suntory’s blue roses contain nearly 100 percent of the blue pigment, it said.
And with that, one more bad bit of poetry bites the dust.
