GM tomato

I won't be queue-ing up for this one I am afraid!

So they crossed a tomato with a snapdragon and bred a purple tomato! Seems pointless when purple tomatoes already exist. If they'd bred a purple dragon it may have been worthwhile.

I’m with you two on this.

It’s buggering about with nature just because they can. I see no benefit from it at all. Apart from the spoiled brat syndrome “look what I can do” .

Probably just a novelty. Most purple tomatoes don't taste very nice to me and I'd prefer to eat berries for anthocyanins.
 
"Liz O'Neill from the campaign group GM Freeze said tomatoes are red for a reason." - Liz clearly needs to expand her tomato horizons. 

As far as I know they are all members of the 'Nightshade' (Solonacaea) family so red would be a warning I imagine? Having said that, in a potato, green would do you harm!

Deadly Nightshade fruits are black/purple - the same colour as the GM tomatoes!

"The scientists in Norwich that developed the purple tomato have now set up a company in California called Norfolk Healthy Produce. They hope to sell its concept."

Looks like the real reason.
