These 40 effectors are not recognized by A. thaliana thus making P. syringae pv. tomato DC3000 virulent against it - that is, P. syringae pv. tomato DC3000 is able to infect A. thaliana - thus A. thaliana is susceptible to this pathogen. [citation needed] Many gene-for-gene relationships have been identified using the two model organisms, P ...
AvrPto is an ancient effector that is conserved in many P. syringae strains, whereas Pto R gene is only found in a few wild tomato species. [18] This suggests recent evolution of the Pto R gene and the pressure to evolve to target AvrPto, turning a virulence effector to an avirulence effector.
"Pseudomonas tomato" is a Gram-negative plant pathogenic bacterium that infects a variety of plants. It was once considered a pathovar of Pseudomonas syringae, but following DNA-relatedness studies, it was recognized as a separate species and several other former P. syringae pathovars were incorporated into it. [1]
Several pathovars of Pseudomonas syringae have been sequenced, including pathovar tomato DC3000 (2003), pathovar syringae B728a (2005), and pathovar phaseolica 1448A (2005). [ 3 ] Distinguishing characteristics

In 2000, the complete genome sequence of a Pseudomonas species was determined; more recently, the sequence of other strains has been determined, including P. aeruginosa strains PAO1 (2000), P. putida KT2440 (2002), P. protegens Pf-5 (2005), P. syringae pathovar tomato DC3000 (2003), P. syringae pathovar syringae B728a (2005), P. syringae ...
