The pathogenicity island and basic master regulators of T3SS genes. a The pathogenicity islands present in the Pseudomonas syringae pv. actinidae M228, compared to gene orientation in P. syringae pv. tomato DC3000 and P. savastanoi pv. phaseolicola 1448a. This orientation shows the similarity and uniqueness of the three strains and their evolutionary aspects. For the orientation of the T3SS cluster of P. syringae pv. tomato DC3000 and P. savastanoi pv. phaseolicola 1448a was adapted from Xie et al. (2019). b HrpL master regulator influenced by different factors, especially HrpX (HrpG, V, U), TCS, and RSM system, and ultimately infects the host plant. c the master regulator hrpG regulated by different sigma factors (PhoPQ) and other factors in P. aeruginosa. The display data was compiled from Anantharajah et al. (2016), Xie et al. (2019)
