ROS as key players in plant stress signalling
TLDR
This review will provide an update of recent findings related to the integration of ROS signals with an array of signalling pathways aimed at regulating different responses in plants and address signals that confer systemic acquired resistance (SAR) or systemic acquired acclimation (SAA) in plants.Abstract:
Reactive oxygen species (ROS) play an integral role as signalling molecules in the regulation of numerous biological processes such as growth, development, and responses to biotic and/or abiotic stimuli in plants. To some extent, various functions of ROS signalling are attributed to differences in the regulatory mechanisms of respiratory burst oxidase homologues (RBOHs) that are involved in a multitude of different signal transduction pathways activated in assorted tissue and cell types under fluctuating environmental conditions. Recent findings revealed that stress responses in plants are mediated by a temporal-spatial coordination between ROS and other signals that rely on production of stress-specific chemicals, compounds, and hormones. In this review we will provide an update of recent findings related to the integration of ROS signals with an array of signalling pathways aimed at regulating different responses in plants. In particular, we will address signals that confer systemic acquired resistance (SAR) or systemic acquired acclimation (SAA) in plants.read more

TL;DR: Identification of two partially redundant Arabidopsis guard cell‐expressed NADPH oxidase catalytic subunit genes, AtrbohD and atrbohF, are reported, providing direct molecular genetic and cell biological evidence that ROS are rate‐limiting second messengers in ABA signaling, and that the AtrbOHD and AtrabohF NADPH oxidationases function in guard cell ABA signal transduction.
