Tomatoes can make purple anthocyanins through all of those enzymes that are naturally in the genome.

So what we did was we added genes encoding these regulators, the switches that switch on and the sign in biosynthesis so that they were switched on at a very late development stage in the fruit, in fruit ripening.
