Plants have to respond to a wide range of biotic and abiotic stresses. They interact with many microorganisms, some beneficial and other harmful, and need to be able to recognize the difference. Their genomes contain large numbers of NBS-LRR and other disease resistance-like genes, the function of most is still unknown. Responses to many abiotic stresses are mediated through a response to reactive oxygen species, allowing common pathways to be activated by many different stresses.
