dc.description.abstract | The Psl polysaccharide has only been studied in Pseudomonas aeruginosa, and its role in bacteria that interact with plants is still unknown. On the one hand, P. syringae is a model of study of plant-pathogen interactions. On the other hand, P. chlororaphis is a biocontrol agent of plant-fungal diseases, as the white root rot caused by Rosellinia necatrix. In silico analysis have let us identify in both species a genomic region which is ortholog to the Psl-encoding region of P. aeruginosa PAO1. We constructed mutants of this region in both strains and analysed its phenotype in biofilm formation, both in static microwell plates and dynamic flow-cell chamber experiments. The results revealed a different and an important role of this polysaccharide in the biofilm architecture of both strains. Furthermore, in P. syringae this Psl-like polysaccharide has a very important role in swarming motility. All these striking phenotypes led us further study the implication of this polysaccharide in the lifestyles of both models of plant-bacteria interaction. | en_US |
