They do appear to have had very little luck with the 
altered flavour so far though!

There is actually no softening supposed to happen after
picking, the tomatoes are both to stay on the plant longer for increased
flavour, and last longer after picking!!
As far as I know the only way it could soften is by some form of ethylene
addition as this affects a different pathway, that the PG antisense does 
not affect(ACC synthase/oxidase, ethylene production).

I'm actually doing a project on this at the moment, 
has anyone got any really good examples of other transgenic
fruit that have been aleterd either for appearance, 
taste or texture etc, I'd be very grateful!
