TL;DR: The motility mechanism of the well-known biocontrol strain Pseudomonas fluorescens F113 is analyzed, indicating that the wild-type motility properties are necessary for competitive root colonization and the possibility of improving competitiveRoot colonization by manipulating the motility processes.

TL;DR: It is shown that the kinB gene, which encodes a signal transduction protein that together with AlgB has been implicated in alginate production, participates in swimming motility repression through the GAC pathway, acting downstream of the GacAS two-component system.

TL;DR: The genome of P. fluorescens F113 is composed of numerous protein-coding genes, not usually found together in previously sequenced genomes, which are potentially decisive during the colonisation of the rhizosphere and/or interaction with other soil organisms.

TL;DR: Phenotypic variants of Pseudomonas fluorescens F113 showing a translucent and diffuse colony morphology show enhanced colonization of the alfalfa rhizosphere, and it is observed that the Gac system regulates swimming motility by a repression pathway, and results show that gac mutations are selected both in the stationary phase and duringRhizosphere colonization.

TL;DR: The ability to form biofilms on abiotic surfaces does not necessarily correlates with efficient rhizosphere colonization or competitive colonization, and a triple mutant gacSsadBwspR (GSW), V35 and V35 were more competitive than the wild-type strain for root-tip colonization, suggesting that motility is more relevant in this environment than the ability to forms biofilm on abiotics.
