abstract：:Abstract To identify virulence genes of P. syringae pv. tomato strain DC3000 we screened for mutants with reduced virulence on its plant hosts, Arabidopsis thaliana and tomato. We isolated a Tn5-insertion mutant that exhibited reduced virulence on both hosts. Further characterization showed that this mutant carried a ...
