*Virulence of the corresponding type III effector mutant expressed as the percentage reduction in gall fresh weight relative to the wild‐type. Degrees of contribution to virulence are as follows: high (H), above 70% reduction in gall size; medium (M), between 21% and 69% reduction; low (L), below 20% reduction; None, no effect on virulence. Results are the average of three independent experiments. Average gall size for Pab4188 or Pag824‐1 in gypsophila is 202 ± 12 mg, and for Pab4188 in beet is 171 ± 10 mg.

^†Gall reduction in mutants was 90% or above.
