We’ve all heard it – tobacco is horrible for our health. So why are researchers growing tobacco plants? Well, in an entertaining twist, they’re actually giving the plants cancer. No, it’s not some strange game of revenge. Researchers have actually found a way to exploit the bacteria that gives plants tumours.
How do the bacteria do this? First of all, they inject their DNA into the plants. The result? The plants are turned into all-night buffets, feeding the bacteria – keeping them nice and comfy. Sure, the affected plant cells turn into tumours, but the unwanted guests don’t really care.
So what are researchers doing with this knowledge? Well, they have found a way to force these bacteria, and thus tobacco plants, to work for them. This is known as genetic engineering. Essentially, researchers give the bacteria a special set of DNA. As a result, the infected tobacco plants make whatever proteins scientists want them to. This is an inexpensive way to make lots of proteins, which is really important in research.
Basically, it’s fun to know that not all tobacco plants are bad.

Target proteins (antigens or antibodies) should be genetically engineered into the cells of edible fruits or vegetables.
Interesting and easy to read article as always, even if the picture link was a little scary. It’s always good to read a simple research blog which contains references to buffets.
