Chemotactic responses to tomato root exudate by R. pseudosolanacearum MAFF106611 and Ps29 strains. The total organic carbon content of tomato root exudate used in this assay was 3.59 g C/liter total organic carbon. Buffer indicates 10 mM HEPES buffer as a negative control. (A) Chemotaxis of R. pseudosolanacearum wild-type strain MAF106611, the mcpA deletion mutant (DMF01), and the mcpM deletion mutant (DMF14). Videotape frames were analyzed at the initiation of observation and 2 min after initiation. (B) Chemotaxis of R. pseudosolanacearum wild-type strain Ps29, the mcpA deletion mutant (DPS01), and the mcpM deletion mutant (DPS14). Videotape frames were analyzed at the initiation of observation and 1 min after initiation. Vertical bars represent the standard errors for measurements done at least in triplicate. Different letters indicate significant differences (P < 0.05 by Student's t test).
