The World’s First Biotechnology — driven “Blue Roses”
Roses have been grown for a long time - 5,000 years or more. It is said that the varieties developed to more than 25,000 species and a wide variety of colours exists including red, white, pink and yellow. For a long time, breeders have been trying to develop blue roses, which have long been synonym for the impossible.In an effort to achieve this breeders have been crossing rose varieties grown all around the world. As a result, there are so- called ‘blue’ roses already on the market. However, blue roses, derived from the presence of blue pigment, have not yet come into being. It has been revealed that this is a result of the fact that in rose petals genes encoding the enzyme that is necessary to create the blue pigment, “Delphinidin”, are not functional (the enzyme is known as flavonoid 3’5’-hydroxylase).
SUNTORY has focused on this finding and, in 1990, in cooperation with an Australian bio-venture company “Calgene Pacific (now: Florigene Ltd.) started the joint development of biotechnology-driven “blue roses”. Since then we have been pursuing our research attempting to develop “blue roses” by retrieving the genes necessary to create blue pigments from other plants such as petunia and implanting these into roses. The world’s first “blue carnations” were born in this development process in 1995 and, in Japan, they were named “Moondust” where they have been marketed since 1997.
For the first time in the world, SUNTORY has succeeded in creating blue pigment in roses by implanting the gene that leads to the synthesis of blue pigment from pansy. Unlike the roses created by using conventional breeding technologies, the roses developed by us have almost 100%* Delphinidin in their petals, which has allowed these new and very different blue roses to become a reality. Although traditional roses have only red pigments, by using the blue roses we have developed as a starting point, it is expected that roses with the ability to create a blue pigment will soon lead more variety in rose flower colour.
