FIG. 2.

Presence of binary ICPs in B. thuringiensis isolates identified by cry35 nucleic acid hybridization. Lanes: 1, molecular mass markers; 2, PS158T3; 3, PS187G1; 4, PS201G; 5, PS201HH2; 6, PS204C3; 7, PS204J7; 8, PS204I11; 9, PS236B6; 10, PS246P42; 11, PS158X10; 12, PS187F3; 13, PS201H2; 14, PS203G2; 15, KR589; 16, KR1209; and 17, PS131W2. The 50% lethal concentration (LC₅₀) (in micrograms per squared centimeters) or N (indicating a dose response could not be calculated) is indicated below each lane. U indicates an undetermined cry34 allele sequence. A− denotes sequences that would be a new tertiary rank, if complete.
