The GTIPP team studies the interaction of bacterial plant pathogens of the genera Xanthomonas and Pantoea with several of its host plants, such as rice, cassava, citrus, banana, barley and wheat. The aim is to increase the knowledge about bacterial virulence and plant resistance mechanisms, thus allowing to better combat bacterial plant diseases, especially in countries from the South (sub-Saharan Africa, Latin America, South-East Asia). The following topics are under study:

• Comparative genomics and transcriptomics of xanthomonads infecting rice, wheat, barley, banana, cassava and citrus;
• Development of high-resolution, high-throughput genetic markers for fast phylogeny and bio-surveillance of plant-pathogenic xanthomonads and Pantoea spp.;
• Transcription Activator-Like (TAL) effectors of xanthomonads infecting rice, citrus, barley and cassava: identification of their virulence targets and engineering of tailored resistances;
• Mapping of qualitative and quantitative resistances to African Xanthomonas oryzae in the germplasm of rice and marker-assisted breeding of improved varieties;
• Engineering of new sources of resistance via targeted genome editing of rice plants;
• Role of small RNAs of rice in the interaction with Xanthomonas oryzae.
