  1. A representative gene member for each family is provided (gene nomenclature from strain GMI1000 unless otherwise stated) with other names published in the literature. Homologues T3E from Pseudomonas syringae sp. (Hop) or Xanthomonas sp. (Xop) are indicated. The last column lists T3E for which Type 3 secretion system-dependent secretion or translocation was experimentally demonstrated.
