Abstract excerpt
The avrPphF gene was cloned from Pseudomonas syringae pathovar phaseolicola (PPH:) races 5 and 7, based on its ability to confer avirulence towards bean cultivars carrying the R1 gene for halo-blight resistance, such as Red Mexican. avrPphF comprised two open reading frames, which were both required for function, and was located on a 154 kb plasmid (pAV511) in PPH: Strain RW60 of PPH:, lacking pAV511, displayed a...
