Oxidative stress tolerance in plants: novel interplay between auxin and reactive oxygen species signaling

Aparna Krishnamurthy et al. Plant Signal Behav. 2013 Oct.

Abstract

Biotic and abiotic stress conditions produce reactive oxygen species (ROS) in plants causing oxidative stress damage. At the same time, ROS have additional signaling roles in plant adaptation to the stress. It is not known how the two seemingly contrasting functional roles of ROS between oxidative damage to the cell and signaling for stress protection are balanced. Research suggests that the plant growth regulator auxin may be the connecting link regulating the level of ROS and directing its role in oxidative damage or signaling in plants under stress. The objective of this review is to highlight some of the recent research on how auxin's role is intertwined to that of ROS, more specifically H2O2, in plant adaptation to oxidative stress conditions.
