Nonhost resistance (NHR), in which a successful pathogen on some plants fails to overcome host barriers on others, has attracted much attention owing to its potential for robust crop improvement. Recent advances reveal that a multitude of underlying mechanisms contribute to NHR, ranging from components shared with recognition-based defenses up to recessive susceptibility factors involved in plant primary metabolism. Most NHR appears multi-factorial and quantitative. This implies that there is no single, ‘silver bullet’ NHR mechanism that can be used to broadly restrict pathogens in many or all crops.
► Nonhost resistance (NHR) protect plants from pathogens adapted to other plant species.
► NHR mechanisms overlap with that mediating host resistance to adapted pathogens.
► NHR can be based on both active and passive defense mechanisms.
