Scientists Genetically Engineer the World's First Blue Chrysanthemum (sciencemag.org) 75

sciencehabit shares an article from Science magazine: True blue flowers are a rarity in nature -- they occur only in select species like morning glories and delphiniums. Now, researchers have created a genuinely blue chrysanthemum by adding two genes to the normally pink or reddish flower. The advance could be applied to other species -- and it may mean that florists wanting to hawk blooms of blue will no longer have to dye them...

The next step for Noda and his colleagues is to make blue chrysanthemums that can't reproduce and spread into the environment, making it possible to commercialize the transgenic flower. But that approach could spell trouble in some parts of the world. "As long as GMO [genetically modified organism] continues to be a problem in Europe, blue [flowers] face a difficult economic future," predicts Ronald Koes, a plant molecular biologist at the University of Amsterdam who was not involved with the work.

      The problem with Na'vi (beyond their impossible weird psychic hair-link with trees) is that only an adult would consider altering themselves to be a giant blue North American Indian analog, but it looks very much like any kind of macroscopic change needs to be done when you're just a single cell... so that kind of change is for your kids.

  • I think the real reason for the necessary "next step" is not concerns about spread of blue flowers into the environment (what could be the harm?) but the inability to control the supply the flowers. So while I find the science interesting, I call BS where I see transparent stab at anti-GMO over making the plant sterile, when clearly the whole thing is an example of GMO.

    • A large proportion of flowers are created fairly easily by cloning through cuttings or tissue culture, so I think the sterility concern is not disingenuous.
    • Patents already cover that. Next time you're looking at potted flowers, check out how many of them have tags that say 'Propagation Prohibited' under the patent number. The floriculture industry always has something new and patented on store shelves. Sterility is not necessary for market control, unless someone somewhere is illegally violating your patent.

      • Plant patents prohibit asexual reproduction (i.e. grafts and cuttings). Sexual reproduction is not prohibited because (loosely speaking) it can't be prevented by the purchaser. Also, sexual reproduction doesn't dependably result in new plants genetically identical to the parent.

    Informed individuals don't have a problem with GMOs, they have a problem with companies that want absolute control of GMOs. While this is a novel thing they have made, the vast majority of GMOs are to make plants resist increasingly caustic herbicides/pesticides. The problem with this is that despite how much you clean it, trace amount of the herbicides/pesticides remain on the plant and if ingested then become part of you and there is no real research into the long term effects of this. What's worse is that herbicides/pesticides don't just land on the crops, trace amounts are in the air which can be enough to kill unmodified plants. On top of that, being unable to use seeds from a previous generation of plant forces a continual dependence on a corporation which is only harmful to everyone but the GMO owner.

    TL;DR: GMOs are fine but corporations are assholes who don't care if you live or die.

    • Informed individuals don't have a problem with GMOs...

      I think I found the flaw in your logic. It applies to vaccines as well.

      • Unfortunately vaccines and GMO have nothing in common.
        The first one is a life saver and the last one a permanent risk.
        And yes: I'm informed about both as we learn about both in school from about age 10 or 12 on ...

        • At the age of 10 or 12 the quality of the education used for complex subjects such as vaccines and GMO is inadequate, and likely to be one-sided.
          • Of course it is more or less one sided.
            It is a school book after all.
            And probably the facts in the book are 20 years outdated, happens often in biology or sports :D

          You should pick up a history book then. Because dousing a rag with cider vinegar and covering your face was considered a life saver against the plague and flu. And vaccines were considered a permanent risk.

          • Having a vinegar rag over your face is indeed helping against catching bacteria, and in case of flue, it will at least filter the air and reduce the risk of catching it.
            However plague is mainly transmitted via flea bites.

            I was of the opinion that the anti vaxing ... oh ... vaccing ... shit red underlined, too ... anyway: the anti scene agains vaccination (ha! not red!) is a new phenomenon?

    • I consider myself informed and there are more worries than just pesticide residue. These plants are often created to be drought and disease resistant on thier own, as well as growing in a wider range of climates. A danger is that these are grown, doubly so in an area where they are not indigenous, in such a way as to escape captivity. It's similar to the same risk imposed by the release of non indigenous species to a region. With GMO like salmon that grow twice as fast this could be a real concern if th
      • For the most part, our crops are not particularly fit in the wild. They are to the wild plants what pugs are to wolves. A change made by genetic engineering will typically be pretty minor compared to the other aspects of the species. With drought and virus resistance, those have only been applied to corn and papaya/summer squash, respectively, and thus far there hasn't been any major ecological issues, although transgenes have been found in wild squash populations. You occasionally have canola or papaya

    • Your post only serves to prove that GMOs are exactly what people oppose. You mention corporate control of them, and yet, plenty of non-genetically engineered crops varieties are also patented. Besides that, those patents expire, like all patents...Monsanto's first generation of GE soybean is now available as an off patent generic...and you fail to clarify what is wrong with a system whereby one makes something superior, gains control of it for a limited time to recoup their R&D costs, then it falls int

    So... Most flowers that look blue are somehow not really "genuine" blue? Could we get some explanation of that? Our local bluebells and bluebonnets look pretty darn blue to my eyes. (I did once find a few mutant "pinkbonnets", by the way! They were cute.)

    The word "blue" has held varied meanings, and what computer systems today define as blue -- the B in our RGB scheme -- would have been regarded as indigo or violet in the not-too-distant past.

    • If the flowers really look blue, then they are blue. However many (perhaps most) flowers "called" blue actually have red components in their color, and are thus some bluey shade of purple of violet. Blue flowers definitely exists, but are a minority for both evolutionary and (related) biochemical reasons.

      The principal claim of "few blue flowers" is really about the commercial flower trade. The major flowers sold by florists are roses, chrysanthemums, carnations, lilies, and gerberas none of whom have any tr

  • Next the Blue Bunny that brings me Ice Cream!

  • So they won't have to worry about the GMO flowers turning them into autistic zombies.

    The Japanese do eat chrysanthemums, so since this was their idea clearly they don't have a problem either.
