which has two separate modes of specificity that are not present in the toxin that is expressed in the genetically engineered plants.

The crystal protoxin does not dissolve in a mammalian system due to the acidic nature of the stomach and there is also no enzyme that will break the protoxin into toxin in mammalian systems (as found in insect guts).

The active toxin expressed in the engineered plants is already solubilized and activated (unlike the spore and crystal preps produced by fermenting the actual Bt bacteria) thus available as a toxin. This is what has not been tested and testing the spore and crystal preparations does not address this issue.
