Nitric oxide (NO) is a multifunctional molecule involved in many physiological processes in plants, especially when exposed to abiotic and biotic stresses. Under these conditions, the cellular content of NO increases in plant tissues to activate defense mechanisms by regulating genes transcription and enzymes activities. Through S-nitrosylation, NO covalently binds to target proteins and the post-translational modification changes its roles in modulating multiple aspects of cellular signaling. It is known the role played by NO on programmed cell death and systemic acquired resistance in plants infected by pathogens. This seminar will discuss the role played by NO in the resistance or susceptibility of plants in response to pathogens infection and how this knowledge may be used as a future strategy for plant disease management.
