Comparison of cell motility of the B. thuringiensis HD73 and ΔcdsR. (A) Analysis of cheV, fliM, motA2, cheR, and fliG1 expression in ΔcdsR and HD73 strains at T₀ by RT-qPCR. Experiments were conducted in triplicate. Error bars represent standard deviations, and data were analyzed using a t-test (*, P < 0.05. **, P < 0.01. ***, P < 0.001.). (B) Cell motility of the ΔcdsR (mutant strain) and CcdsR (complementary strain) were compared with that of the HD73 (wild-type strain). The cell motility of B. thuringiensis strains was observed in LB solid medium containing 0.5% agar. (C) Comparison of plaque diameters of the ΔcdsR, CcdsR, and HD73. Five independent experiments were used to analyze the data by t-test (****, P < 0.0001).
