Oxidative burst in plant-pathogen interaction
Journal Title: Biotecnología Vegetal - Year 2011, Vol 11, Issue 2
Abstract
The production of reactive oxygen species (ROS) via consumption of oxygen in a so-called oxidative burst is a hallmark of successful recognition of infection and activation of plant defenses. ROS are not only toxic by-products of aerobic metabolism, but are also signalling molecules involved in several developmental processes in all organisms. Previous studies have shown that an oxidative burst often takes place at the site of attempted invasion, during the early stages of most plant-pathogen interactions. For this reason, in order to cope with the deleterious effects of these molecules, plants are fitted a large panel of enzymatic and non-enzymatic antioxidant mechanisms. Here, is presented some of the main aspects which are related with ROS role during plant-pathogen interaction.
