PhD Understanding the link between metabolism and behaviour in plant growth-promoting bacteria

Pseudomonas fluorescens is a widespread, plant-associated bacterium that colonizes roots and contributes to plant growth and disease suppression. To successfully colonise the rhizosphere, P. fluorescens must coordinate expression of phenotypes such as motility and biofilm formation with adaptive remodelling of central metabolism to take advantage of available nutrients. While much research has been conducted into both bacterial behaviour and metabolism, we have relatively little understanding of how these two important processes are integrated into a coherent environmental response.
