REACTIVE OXYGEN SPECIES AND THEIR ROLE IN PLANT DEFENSE AGAINST PATHOGEN INGRESS
Journal Title: Int J of Pharm Rev& Res - Year 2014, Vol 4, Issue 1
Abstract
Pathogen infections induce a rapid accumulation of Reactive Oxygen Species (ROS) in plant tissues termed as oxidative burst which is the earliest event in the plant defense response. In non-stressed plant tissues enzymatic and non-enzymatic antioxidants are able to neutralize the harmful effects of ROS. The Oxidative burst at the plant cell surface drives rapid peroxidase-mediated oxidative cross-linking of structural proteins in the cell wall, thereby reinforcing this physical barrier against pathogen ingress. ROS serve as a second messenger in a systemic signaling network in plant immunity and leading to the expression of defense genes, phytoalexin production, and triggering of a hypersensitive response (HR). Rapid production of ROS has been implicated in diverse physiological processes including resistance to biotic and abiotic stress. The requirement for ROS appears to be different for resistance to different pathogens
