a
Putative function and homology to known type III effector proteins from Pseudomonas syringae or other Xanthomonas spp. For Pseudomonas effectors, the unified nomenclature was used (55).
b
Homologs were determined using BLAST algorithms. −, absence of a homolog; +, presence of a homolog; (+), partial homology or a disrupted homolog in the corresponding genome (Xac, X. axonopodis pv. citri; Xcc, X. campestris pv. campestris; Xoo, X. oryzae pv. oryzae; Pst, P. syringae pv. tomato; Rs, R. solanacearum; Eca, E. carotovora subsp. atroseptica).
c
Putative type III effector, not experimentally verified.
