Changes in metabolites due to abiotic stress help fight plant pathogens
Plant pathogens pose a major threat to crops. Although certain abiotic stressors can provide resilience to subsequent pathogen infection, the molecular mechanisms underlying this phenomenon are poorly understood. The EU-funded MICROBIS project will address this knowledge gap by identifying changes in metabolites that enhance plant tolerance to pathogens following periods of abiotic stress. MICROBIS will cultivate the model organism Arabidopsis and expose it to water and temperature stress followed by a pathogen and then measure and analyse metabolome changes. Finally, artificial intelligence algorithms will be applied to select species of agronomic interest that metabolically respond to sequential stress as Arabidopsis does. The results will help to develop new strategies to ensure food security under current climate change conditions.
