AB The presence of genetic determinants homologousto rulAB genes for ultraviolet (UV) radiation resistance wasdetermined in a collection of Pseudomonas syringae pv.syringae strains isolated from mango. The potential role ofthese plasmids in UV tolerance and ecological fitness in themango phyllosphere was also evaluated. Nearly all of the62-kb plasmids present in the P. syringae pv. syringaestrains hybridized with a rulAB probe, but these 62-kbplasmids showed differences in restriction patterns. In vitroassays of tolerance to UV radiation of P. syringae pv.syringae strains showed a higher survival of the strainsharboring the 62-kb plasmids compared to strains lackingplasmids when exposed to UVC or UVA+B fractions.Similar results were observed when transconjugants harboringthe 62-kb plasmid were tested. Survival assays werecarried out under field conditions, and a higher survival ofP. syringae pv. syringae strains harboring 62-kb plasmidsunder direct solar radiation on the adaxial surface of leaveswas also observed. When the assays were carried out in shady areas or on the abaxial surface of leaves, survivaltime was comparable for all the assayed strains, whether ornot they contained a 62-kb plasmid hybridizing to rulAB.Our results indicate that P. syringae pv. syringae strainsharboring 62-kb plasmids show an increase in ecologicalfitness when colonizing the mango phyllosphere.
