The Rizosfera-UAM group is interested in the molecular mechanisms that promote the colonization of the rhizosphere by rhizobacteria. We use the model Pseudomonas fluorescens F113, PGPR and with applications in agriculture and bioremediation. We study the signal transduction mechanisms in response to environmental changes during the root colonization process. Our study focuses on the regulatory node formed by the global transcription factors AmrZ and FleQ and on the traits regulated by them: mobility, c-diGMP production, biofilm formation, secretion systems, etc. We carried out phylogenomic studies, which have allowed us to identify 8 subgroups within the fluorescens group, with P. corrugata, P. protegens and P. chlororaphis being the best PGPRs. Regarding knowledge transfer, we isolate and characterize natural consortiums and Synthetic Communities (Syn Coms) for the promotion of plant growth and soil bioremediation.
