In Silico Characterization and Phylogenetic Distribution of Extracellular Matrix Components in the Model Rhizobacteria Pseudomonas fluorescens F113 and Other Pseudomonads.

ABSTRACT: Biofilms are complex structures that are crucial during host-bacteria interaction and colonization. Bacteria within biofilms are surrounded by an extracellular matrix (ECM) typically composed of proteins, polysaccharides, lipids, and DNA. Pseudomonads contain a variety of ECM components, some of which have been extensively characterized. However, neither the ECM composition of plant-associated pseudomonads nor their phylogenetic distribution within the genus has been so thoroughly studied. In this work, we use in silico methods to describe the ECM composition of Pseudomonas fluorescens F113, a plant growth-promoting rhizobacteria and model for rhizosphere colonization. These components include the polysaccharides alginate, poly-N-acetyl-glucosamine (PNAG) and levan; the adhesins Lap
