Dexamethasone‐inducible expression of avrPto in Arabidopsis promotes the in planta growth of Xanthomonas campestris pv. campestris (Xcc) wild‐type and ΔhrcC strains after vacuum infiltration. (A) Population sizes of Xcc B186 wild‐type and ΔhrcC strains in transgenic plants carrying avrPto under the control of a dexamethasone‐inducible promoter (+avrPto), or nontransgenic Col gl‐1 plants (‐avrPto), after spraying plants with dexamethasone (Dex) or with buffer (mock) 24 h prior to inoculation. (B) Population sizes of Xcc B305 wild‐type and ΔhrcC strains in an experiment similar to that in (A). All data are means ± standard error. *Significant difference from the same strain on ‐avrPto plants (t‐test, P < 0.05). cfu, colony‐forming units.
