Figure 4From: Mutagenesis of RpoE-like sigma factor genes in Bdellovibrio reveals differential control of groEL and two groES genesLengths of flagella and swimming speeds of the mutants and wild-type. A- Flagellar length of wild type and sigma factor mutants measured from electron micrographs, error bars show 95% confidence intervals. B- Speeds of wild type and mutant predatory strains measured by the Hobson Bactracker, error bars show 95% confidence intervals.Back to article page
