Role of Specific Quorum-Sensing Signals in the Regulation of Exopolysaccharide II Production within Sinorhizobium meliloti Spreading Colonies
Figure 3
The role of EPS I and EPS II in surface spreading.
When S. meliloti 8530 mutants defective in EPS I (exoY, Rm11603) and EPS II (wgaA, Rm9030-2) biosynthesis were tested on 0.4% soft agar surfaces, only EPS II-deficient mutant was unable to spread.
