Australian and Japanese researchers have made the old dream of botanists come true: they have achieved a blue rose. For this purpose they have used RNA technology. This has meant the substitution of one gene for another, in particular the gene encoding the enzyme dihydrofabonol reductase, by a gene equivalent to the same enzyme of the common lily. It is the gene that gives the pigment of blue color. Thus, pink does not produce pink pigment, but blue.
