Salicylic acid (SA) plays a major role in inducing systemic acquired resistance, a natural plant defense mechanism against pathogen attack. This is evident in the high concentration levels of SA in a tobacco plant infected with tobacco mosaic virus. Besides this, SA assists in developing genetic resistance to diseases. H2O2, unlike SA, apparently does not induce systemic acquired resistance, even though SA inhibition of catalase gives rise to accumulation of H2O2. more...
