Colonization of Wt and Δexlx–gh5 strains in plant xylem. (a) Squash seedlings were inoculated with either Wt or Δexlx–gh5. At 12 days post inoculation (DPI), bacterial concentration was determined in the inoculation site and in a petiole of a second, non-inoculated leaf. (Sample sizes, n = 9 per treatment). (b) In trans complementation of Δexlx–gh5 and Wt. Plants were co-inoculated with a 1:1 mix of Wt & Δexlx–gh5. (Sample sizes, n = 11 per treatment). Y-axis is the log10 CFU/g fresh weight and is scaled to the lower limit of detection for the assay (log10 CFU/g fresh weight = 2.6). Bars show mean ± SE, and circles are individual biological replicates. **P < 0.005; ns non-significant.
