Plants roots are surrounded by communities of microbes (i.e. the "rhizosphere microbiome"); these microbes influence plant growth, development, and disease resistance. Using the model plant Arabidopsis and its associated bacteria, such as Pseudomonas fluorescens, our lab studies the genetic and environmental factors that regulate plant-microbiome associations. Our current projects are focused on: Uncovering how microbes, including P. fluorescens,…
