Bsi regulates swarming initiation in response to red, but not blue, light. The timing of tendril formation was compared in the wild-type P. syringae pv. syringae B728a, Δbsi, and Δbsi(pHbsi) strains in white light (A), red light (B), and blue light (C). Values, error bars, statistical analyses, experimental replication, and abbreviations are as described in the legend to Fig. 1.
