Apple Gene for Red Color Found 180

FiReaNGeL writes "Researchers have located the gene that controls the red color of apples — a discovery that may lead to bright new apple varieties. 'The red color in apple skin is the result of anthocyanins, the natural plant compounds responsible for blue and red colours in many flowers and fruits,' says the leader of the CSIRO. By identifying master genes that were activated by light, they were able to pinpoint the gene that controls the formation of anthocyanins in apples. 'As well as giving apples their rosy red hue, anthocyanins are also antioxidants with healthy attributes, giving us plenty of reasons to study how the biochemical pathway leading to apple color is regulated,' researchers said."

      It's called a tattoo.

      Fortunately, fashions change and it's probably not a good idea to tattoo your make-up on.

      Apples, well, they'll still go bad, and so changing their color will probably not hurt anything.

      It's only on the outside, I mean, they already come from greens and yellows to red. Blue will just stand out against the leaves of the trees and be more suseptable to pests and other fun things that eat fruits to live. At least that makes sense in my head; I am not an apple farmer.

    My family is heavily into organic food, and now that I am out of the house, I still try to eat stuff grown reasonably well, for taste and health reasons. But anyway, back at my old house, there were a number of apple trees in the yard when we moved in. One tree always has apples that look like they are covered in dust. The other trees don't. Blemishes and bumps are common, along with the occasional worm. Nothing in the supermarket, "organic" or otherwise, compares. Firm, not full of water, not ridiculously crispy, and have more of the taste of an apple than any other apple I have tried.

    The way an apple looks matters little to me. Sure, the inability to wipe the dirty appearance off the apples put me off at first, but I now know that a bright red apple will taste more like water than anything else. And now thanks to the discovery of this gene, mega-orchards can grow good looking crops with far less effort, fertilizer, or taste, I would expect.

    Things like this make me consider dropping out of the sciences. Every advancement seems to merely be another opportunity to cut back something else, and get away with less bottom-line. Still, maybe with the extra anti-oxidant thing, it could be worth it.

      Apples taste is chiefly controled by their genetics. Essentially, watery and tart apples tend to be early summer apples and crips and sweet ones are late fall varieties. There is, essentially an direct correlation/tradeoff with maturing time and taste. Everything else that the farmer does only affect this a tiny bit. Otherwise they could turn their Melbas into Cortland just by spraying them which simply doesn't happen.

      The weather that year also plays an important role, mainly rainfall and the amount of sun and heat. That's easily demonstrated as the main factor by the simple fact that all the farmers in a region get the same kind of results for a given year (small red apples, big lightly colored ones, fragile things that fall on the ground).

      In fact chemicals are very expensive to an apple grower so you can bet that they try to use them as little as they can.

      That's not to say that they don't spray, they do spray a lot but it's in their best interest to spray as little as possible and many are trying to limit their use of chemicals.

      If there is anything wrong, it's the association in consumer's mind of the red color and ripeness. You can have perfectly sweet and ripe fruits but that aren't all that red. This has lead to variety (like the delicious) that is very red but has no taste. To each his own.

      • Chemicals may be expensive in some cases, but I believe in general chemical fertilizer is cheaper than transporting compost, when crops are grown in large batches. I think "you are what you eat" applies to apples as well as anything, and a bag of chemicals... is not going to taste as good as a bag of composted leaves, windfall, and faecal matter. OK, never mind that analogy.

      Manipulating the genetics to get redder apples means that color will be even less of an indication of ripeness than it is now. The Delicious variety of apples in the grocery store are always bright red but usually not very good tasting. I once heard that the Delicious apples were bred more for color than taste. If I remember correctly, I also also once read about apples and possibly even salmon being gassed to alter color. Is that correct? I don't know if that is commonly done or not.

    bright new apple varieties.

    Maybe not. There was just a nobel prize awarded in this area of research. IIRC, the gene expression is regulated by a twisted helix RNA type which prevents overexpression of given genes, and there's some feedback mechanism which causes the chromosomal DNA to stop expressing the mRNA after a while.

    The original studies which started this were botanists trying to make more pink petunias - when they inserted more "pink" genes, the petunias came out white. The prize research was about regulation in c.elegans.

    Botanists and molecular biologists will now shred my analysis. :)

      I read somewhere that the wide array of new colours in petunias (which when I was a kid, only came in white, red, pink, and red/white striped) derive from the addition of genes from corn.

The next generation's blooms were strange, to say the least. Some had irregular white blotches; others were delicately shaded, like watercolours that had gotten wet. Many had a crepe or wr

      I'm not an "ordained" molecular biologist, but I'll add to your comments. Bright new apple varieties can be introduced into apples via genetic manipulation at the chromosomal (genomic) DNA level. In organisms, from plants to animals, you can inject (or "transfect") a specific gene into a cell relatively easily. This type of injection can be permanent or temporary. A permanent injection could yield a new apple variety. This is direct genetic manipulation.

They introduce a huge selective pressure for color and isolate the apple from any selective pressure for taste.
