The first true blue rose
Saturday, October 27th, 2007The first true blue rose was created by the Australian and Japanese molecular geneticists under the companies Florigene and Suntory. After 13 years of joint research between the two companies, the genetically engineered blue rose was created in 2004, and it was no easy work.
Traditionally, blue roses were only made possible by dyeing white roses blue. This is because roses lack the delphinidin gene, which is the gene that produces the blue pigment, and attempts to make true blue roses by breeding roses with the blue pigment were unsuccessful.
So how was the first true blue rose created?
1. The red pigment was turned off by silencing the dihydroflavonol reductase (DFR) gene, which is the gene that produces the red pigment.
2. The blue pigment gene was added by inserting the delphinidin gene, which was cloned from pansy, to direct pigment synthesis in the rose.
3. The DFR gene from iris was added to complete the delphinidin-synthesis reaction.
So what inspired me to write about the blue rose?
