WebJul 26, 2001 · We determined that Bacillus thuringiensis Cry1Ac and Cry1Fa delta-endotoxins recognize the same 110, 120 and 170 kDa aminopeptidase N (APN) molecules in brush border membrane vesicles (BBMV) from Heliothis virescens. The 110 kDa protein, not previously identified as an APN, contained a variant APN c … WebFour isofamilies from Puerto Rico were very tolerant to Cry1Fa and not so tolerant to Cry1Ac. Two of the four isofamilies were backcrossed with a Bt-susceptible laboratory colony and their progeny was as susceptible to both Bt proteins as was the Bt-susceptible colony, indicating that resistance to Bt is a recessive trait.
