Summary : Plant survival to biotic stresses results from various defence strategies. Depending on the pathogen and nature of the parasitism, a plant will adapt its responses through a fine-tuning regulation of defence mechanisms under the control of its hormones whose functions will be reoriented. Salicylic acid, jasmonic acid and ethylene drive signalling pathways, the role of which is well established in plant resistance. However, additional hormones, including abscisic acid, seem to have an essential role in plant defence regulation. Crosstalk and coordination of these signalling pathways are key elements for the expression of optimized plant resistance to pathogens. |
