Figure 2. Effect of Y. pestis GGDEF-, EAL-, and HD-GYP-domain genes on in vitro biofilm formation.

Figure 2

A, B. Relative amounts of adherent biofilm made by Y. pestis KIM6+ parent strain and isogenic derivatives deleted of (A) or overexpressing (B) one of the genes listed in Table 1. C. Quantitation of biofilm made by the hmsT hmsP y3730 triple mutant strain overexpressing one of the genes listed in Table 1, or the mutated y3730 GGAAF allele. The mean and standard deviation of two or more independent experiments are indicated.
