Agarose (1%) gel electrophoresis of PCR products amplified with the set of primers Un1(f)/Un1(r) (a), Un2(f)/Un2(r) (b), Un9(f)/Un9(r) (c), and vip3-sc(f)/vip3scII(r) (d), which reveal the presence of genes from the cry1, cry2, cry9, and vip3 families, respectively. Bacillus thuringiensis isolates were considered positive for the studied gene when their genomic DNA amplified with the corresponding primers and gave a band of the expected size.
