Deciphering the impact of nutrient stress in mycorrhiza-induced resistance against Botrytis cinerea in tomato

Abstract: R. irregularis colonization of tomato roots results in a defence priming increasing resistance of the shoots to B. cinerea. Perception of a nitrogen starvation has a negative impact in the plant resistance to pathogens. AM plants antagonize this negative impact of N starvation perceiving more efficiently N depletion than NM plants and activate the hormone regulation responses faster and stronger.
