Fig. 2.

Both species of farmer-associated Burkholderia isolates are attracted to amoeba secretions. The figure represents combined boxplot/violin plot diagram. Because all blank controls are zero, they are excluded from the figure (violin plot cannot be created). Results show D. discoideum supernatants invoked a strong chemotactic response by the carried Burkholderia, and that chemotaxis responses are affected by both partners. Significant differences in chemotactic responses are indicated by different letters, which reflect results of a post-hoc Tukey’s HSD test (Table 1). Letters apply both within and between panels (letters are the same). However, comparison between the two panels is in a pairwise pattern (vertical columns)
