Requisiteness of reactive oxygen species (ROS) in plant-microbe interactions

Abstract

Reactive Oxygen Species (ROS) are profoundly generated as an outcome of various adverse challenges to plants. ROS are responsible for signaling in very small amounts in addition to their involvement in various developmental actions. An oxidative burst at the pathogen challenge site is the first reciprocation to phytopathogen association. ROS productions during the interaction of beneficial microorganisms lead to the induction of plant defense responses by scavenging excess ROS. The ROS entailments in plant-microbe interaction whether the pathogenic and beneficial association is very similar despite the function they perform are different. In the present chapter, we review ROS management and signaling during plant-pathogen and beneficial microorganism interactions. © 2023 Nova Science Publishers, Inc. All rights reserved.
