Naturally occuring roses cannot make blue pigment delphinidin


IT’S not royal blue or even sky blue, but blue enough to lay claim to the title of the world’s first blue rose.



Australia’s Gene Technology Regulator has granted a licence to Florigene for commercial release of a genetically modified Hybrid Tea rose which expresses genes for the colour blue.



Naturally occuring roses lack enzymes responsible for the production of the blue pigment delphinidin. The new rose line contains the Flavonoid 3’5’-hydroxylase gene from Viola tricolour and the Anthocyanin 5-acyltransferase gene from Torenia x hybrida, expressed in the epidermal layer of flower petals to cause production of delphinidin pigments.



The GM rose also contains a marker gene for resistance to aminoglycoside antibiotics related to kanamycin and neomycin. The GM line is a periclinal chimera so its pollen does not contain the introduced genes.



Regulatory sequences from Cauliflower mosaic virus, Tobacco mosaic virus and Agrobacterium tumefaciens have also been inserted to control expression of the introduced genes.

      Florigene plans blue rose field trials
      Graeme O'Neill 23/08/2005 13:14:01

      Melbourne-based novelty flower developer Florigene is planning the first field trial of its genetically modified roses carrying the company's proprietary 'blue gene' technology.

      The nation's gene technology watchdog, the Office of the Gene Technology Regulator (OGTR), announced this week that Florigene has applied for permission to run a small (0.01 hectare) glasshouse-contained field next year of three rose varieties engineered with a pansy transgene that diverts pigment synthesis into the 'blue' delphinidin pathway.

    • the "traditional blue rose" by the way hippies use grape cool aid to turn any hemp into the purples...........

      OK I went to the horses mouth and this is all we get

      pictures of a patented GMO are copy righted too!!!

    • With regard to purple/lilac roses, they have existed naturally for ages. They have a very strong scent and survive longer than any other rose after being cut. I had purple roses in my wedding bouquet when I got married in 1983.

    • The roses in the photo above are not blue roses, they are white roses which have had blue ink added to the water in their vase - no, that is not my secret method. If you look attentively at that photo, you will notice that the leaves also have a blue hue, due to the ink. One can colour cut white roses in any colour by adding coloured ink to the vase water, and the leaves will also take the hue.

      Edit: The photo was changed since I posted this.

    • A great-aunt of mine knew how to grow blue roses, and that secret method has been passed on to me, so I've grown some too in the past, mystifying horticulturists in the process! No, I am not telling, it is a family secret, and has absolutely nothing to do with genetic engineering.

    • Although all of these sequences are derived from plant pathogens, the regulatory sequences comprise only a small part of the pathogen’s total genome, and are not in themselves capable of causing disease,” the regulator’s decision said. It concluded that the new rose poses negligible health and environmental risks.

      “Nonetheless, general licence conditions have been imposed to ensure that there is ongoing oversight of the release,” the decision said. “These conditions relate to ongoing licence holder suitability, auditing and monitoring, and reporting requirements which include an obligation to report any unintended effects.”

      Six years after it was founded in Melbourne in 1986, Florigene gained patents over use of a petunia gene which imparts blue flower colour. In 1994 it successfully implanted the gene into carnations to create a GM range which has been commercially available worldwide for some years. In 2003 the company was acquired by the Suntory group of companies but its research is still conducted in Melbourne.
