Fig. 3From: Molecular study on the carAB operon reveals that carB gene is required for swimming and biofilm formation in Xanthomonas citri subsp. citri Bacterial growth and biofilm formation. a Growth curve of ΔcarA and ΔcarB mutants in NB media. b Biofilms of ΔcarA and ΔcarB mutants formed in a microtiter plate and stained with crystal violet. c Quantitative measurements of biofilm formation. The experiments were repeated three times. The asterisks in horizontal data column indicate significant differences at P = 0.01 by t testBack to article page
