Representation of NO signalling functions during the HR. CHS, chalcone synthase; CA, cinnamic acid; Ca2+, calcium influx; cADPR, cyclic cADP ribose; cGMP, cyclic GMP; MAPK, mitogen-activated protein kinase; PAL, phenylalanine ammonia lyase; PHE, phenylalanine; PR, pathogenesis-related proteins; SA, salicylic acid; BA, benzoic acid. Dotted lines represent potential NO functions
