Iron deficiency response of interactions between Brachypodium and Pseudomonas fluorescens SBW25 under controlled growth conditions.
The goal of this study was to evaluate the molecular mechanisms by which Brachypodium distachyon grown with and without Pseudomonas fluorescens (P. fluorescens) strain SBW25 respond to Fe deprivation. Fe deprivation induced Brachypodium secretion of phytosiderophores and reduced biomass production while inoculation with P. fluorescens resulted in alterations of extracellular metabolite abundances. Results provide insight into the role of iron in interactions between a host plant and root associated bacteria. Overall design: Examination of transcriptional profiles from Brachypodium distachyon BD21 and Pseudomonas fluorescens SBW25 under sterile vs inoculated with and without Fe amendment.
