Project

Synergies of plant-beneficial bacteria and interactions with lettuce rhizosphere microbiota to control a fungal disease
This research project explores the synergies between plant-beneficial bacteria of the genera Pseudomonas and Bacillus and their interaction with different soil microbiota to control the pathogenic fungus Sclerotinia sclerotiorum, responsible for white mold in lettuce. This disease causes major losses in lettuce production and other crops of economic importance, such as canola. Currently, synthetic pesticides are the main control method, but they pose problems of resistance and environmental impact. The project aims to identify synergistic bacterial combinations capable of controlling this fungus more effectively than current pesticides. It also aims to study the role of soil microbial community structure in the establishment of phytobeneficial bacteria and their ability to control the fungus. The project combines classical microbiology and molecular biology techniques with a wide range of next-generation sequencing tools, bioinformatics and modeling methods. It will contribute to the development of more effective and sustainable biopesticides, improving crop protection while reducing the use of synthetic pesticides.
