Bacterial type six secretion systems (T6SS) are multiprotein complexes involved in the translocation of toxins and/or effector proteins directly to prokaryotic or eukaryotic target cells, playing roles is antibacterial competition, virulence and resistance to eukaryotic predators. The Xanthomonas citri T6SS is an anti-eukaryotic device that is required for resistance to predation by the s…
