Gabriella Pessi is a researcher in the Department of Plant and Microbial Biology with a focus on nitrogen fixation and beneficial plant-microbe interactions. Her work specifically investigates Paraburkholderia strains associated with legumes, which establish nitrogen-fixing symbiosis and offer protection against phytopathogens. Utilizing a multidisciplinary approach, she employs high-throughput genome-wide molecular screening methods including Tn-Sequencing, RNA-Sequencing, and shotgun proteomics metabolomics, alongside targeted mutant analysis and phenotypical analysis microscopy. Her research objectives are to elucidate the genetic basis for the ability of plant-associated Paraburkholderia strains to competitively infect legume roots, facilitate nodulation across a broad spectrum of legumes to provide fixed nitrogen, and enhance plant resilience against phytopathogens. Gabriella's work contributes to understanding the molecular foundations of beneficial plant-microbe interactions, aimed at developing novel rhizobial inoculants for sustainable agriculture and crop protection.
