Rabies Antibodies From Tobacco Plants

Makarand writes "The tobaccco plant has been genetically engineered to produce rabies antibodies. After the DNA coding for the human antibody against rabies was inserted into the plant, rabies antibodies were found in the plant extract. These antibodies were effective in binding to and neutralising the rabies virus in animal tests with no adverse or allergic reactions."

      We have been cross-breading plants for thousands of years. Most of the grains we eat today are carefully bread. Laura Wheat - which is a popular wheat because it is much more hardy - has been bread with several other types of grain, to have beards like durum - helps prevent inspects and rodents from eating all the grain. Different plants are bread together in the interest of creating something better. It is slow, costly and unreliable. You can get plants with all sorts of negative traits you don't want. But, we do it and pretty much all the food we eat has been engineered this way. It is "oldschool genetic engineering", if you will - sit back and hope, method.

      Another thing we do to plants - even some the wonderful "safe, organic" plants: desiccation and irradiation. The most common is dumping chemicals on plants to dry them out quickly for harvest. The result is seeds that are so badly damaged they won't germinate. But they're still used as food. We irradiate food to kill off disease. Chemicals and radiation are also used to control reproduction - either to prevent grains from going to seed or making sure that the seeds of the plant (grown from the original "modified" seed) cannot germinate. This forces farmers to always buy the grain from the distributor, instead of being able to reuse seed that they've grown.

      As scary as desiccation and irradiation are, they help preserve food and eliminate diseases. There are also all the incredibly toxic chemicals we spray onto most foods in order to keep disease and pests off them. Which may be good - it lets us produce food in volumes many times larger than what we could do without. It also helps keep prices at the low levels most people seem interested in paying. (Many organic farmers go out of business - too few people want to pay the higher prices caused by the reduced output)

      Personally - I would be much happier having no chemicals used on the food I eat. If a genetically engineered plant, that has been tested to be safe, can live with no chemicals and produce as well as our current crops, I'd be very happy.

      I think we should stop looking at Genetically Modified/Engineered food as a demon. We've done genetic engineering for years, we've just got new techniques. Instead of spending our efforts on blocking and preventing it, I'd far rather develop tests and controls to ensure that when we DO create GM plants, we have good controls in place to test the safety and prevent cross-contamination.

      Genetic engineering is a tool like any other - if used improperly, it is dangerous, if used correctly, it is very beneficial. And, like anything else, if you prevent people from doing it in your country - it will simply move into more remote, less controlled places. I'd rather encourage its development safely than chase it to some place where it can develop dangerously.

      What's needed is a safety mechanism. I have seen research that rendered yeast (IIRC) dependant on an amino acid that does not occur naturally (yet is easily synthesized). A good measure would be to make the same modification to the plant's genetics so that won't grow at all outside of it's controlled cultivation environment.

      Another useful modification would be a sterile plant that is reproduced only from cuttings. As a side benefit, this would also control genetic drift that could render it useless for it's intended production.

      Actually, organic foods are slowly becoming mainstream. Organic farmers in the past have gone out of business for two primary reasons. One is that they simply stopped using pesticides and herbicides but made no other changes to their practice (a sure recipe for disaster). The other is that organic foods have been a sort of fringe thing.

      When appropriate techniques are used such as mixed crops and avoiding strains which require 'modern' techniques to thrive due to inferior insect resistance or ability to absorb nutriants, production is much better.

      Organic food is starting to become mainstream now. Unlike 5 years ago, you can now find it in mainstream grocery stores. The larger market for organic foods will help organic farmers considerably.

      While I don't view GM foods as a demon, I do view it with additional caution. It is a more powerful tool, and as such, can cause bigger harm more quickly than traditional breeding techniques. In traditional breeding, the desired change comes about over a number of plant generations, with undesired emergant traits selected against in each generation. In GM techniques, that all gets squashed into a single generation of change. This naturally calls for an order of magnitude (at least) more care in selection of the modified generation.

      Then there's the degree of change. Unlike traditional techniques where traits must be selected from existing plants similar enough to cross breed, GM techniques can introduce traits that have never even existed in the plant kingdom before. That capability SHOULD suggest considerable additional caution with the modified generation since it can produce entirely unexpected results (imagine the surprise of someone allergic to shellfish when they have a near fatal reaction to grapes for instance).

      Given the history of the companies involved in much of this (not all, but many), there is ample reason to doubt that that necessary extra care will be taken (though you can bet we'll be TOLD that it is taken, and there might even be fake documentation to back it up, they have a history of falsifying safety studies).

      Imagine if, for example, some genius in the '50 had managed to get tomatos to produce DDT in their leaves (after all, it's only in the leaves, and we all know DDT is safe to use anywhere). Though he wasn't able to make sure the trait wouldn't cross into other varieties, he was able to make sure it would only be expressed in the leaves, so it was 'perfectly OK' if it spread into every variety of cultivated tomato.

      While some are opposed to GM in principle out of fear, many others are opposed simply because they do not believe that the corperations involved can ever be trusted to use appropriate caution when there's a dollar to be made.They fear the day some agribusiness decides that the 90 billion they'll have to pay out in lawsuits will be less than the 100 billion they will make, and that in any event, the lawsuits probably won't happen before ten years pass and the stockholders are grumbling now (side note, consider if executives are 9 years from retirement).
