Bt toxins

Hi Everyone
I read this claim recently:
> Toxins used in transgenic food crops are plant-produced Bt
> toxins called cry" toxins and they can be modified for specific
> results, such as to kill only unwanted insects. Also, these Bt
> toxins are only present in plant foliage, not the grain
I have heard the opposite claimed, that the toxins are present in all parts of the plant. I have heard that "every mouthful of Bt potato contains a dose of Bt pesticide"
Where does the truth lie?
