Development of alternative approaches for controlling diseases and promoting plant productivity using plant beneficial bacteria

Current research and/or projects

  • Control of plant pathogens by using plant beneficial Pseudomonas spp.

  • Biofertilization and improved crop yields using plant growth promoting rhizobacteria.

  • Rhizocompetence of plant beneficial bacteria and development of approaches to promote their presence under field conditions.

  • Soil health and characterization of taxonomic and functional microbial diversity under field conditions.

  • Development of molecular diagnostic tools to track targeted bacteria under soil conditions.

  • Population genetics and spatio-temporal monitoring of bacterial plant pathogens.

  • Functional genomics of plant beneficial Pseudomonas spp.
