TLDR
The most challenging contemporary questions in the field of plant ROS biology are outlined and the need to further elucidate mechanisms allowing sensing, signaling specificity, and coordination of multiple signals is outlined.Abstract:
As fixed organisms, plants are especially affected by changes in their environment and have consequently evolved extensive mechanisms for acclimation and adaptation. Initially considered by-products from aerobic metabolism, reactive oxygen species (ROS) have emerged as major regulatory molecules in plants and their roles in early signaling events initiated by cellular metabolic perturbation and environmental stimuli are now established. Here, we review recent advances in ROS signaling. Compartment-specific and cross-compartmental signaling pathways initiated by the presence of ROS are discussed. Special attention is dedicated to established and hypothetical ROS-sensing events. The roles of ROS in long-distance signaling, immune responses, and plant development are evaluated. Finally, we outline the most challenging contemporary questions in the field of plant ROS biology and the need to further elucidate mechanisms allowing sensing, signaling specificity, and coordination of multiple signals.read more

TL;DR: HPCA1, a member of a previously uncharacterized subfamily of leucine-rich-repeat receptor-like kinases, is the hydrogen-peroxide sensor at the plasma membrane in Arabidopsis and helps to identify how the perception of extracellular H2O2 is integrated with responses to various external stresses and internal cues in plants, and have implications for the design of crops with enhanced fitness.

Reactive oxygen species signalling in plant stress responses
TL;DR: In this article , the authors discuss promising developments and how they might be used to increase plant resilience to environmental stress, including the identification of ROS receptors and key regulatory hubs that connect ROS signalling with other important stress-response signal transduction pathways and hormones, as well as new roles for ROS in organelle-to-organelle and cell-tocell signalling.

TL;DR: It is shown here that RHD2 is an NADPH oxidase, a protein that transfers electrons from NADPH to an electron acceptor leading to the formation of reactive oxygen species (ROS) and that ROS accumulate in growing wild-type (WT) root hairs but their levels are markedly decreased in rhd2 mutants.

Calcium channels activated by hydrogen peroxide mediate abscisic acid signalling in guard cells

TL;DR: Activation of Ca2+-permeable channels in the plasma membrane of Arabidopsis guard cells by hydrogen peroxide indicates that ABA-induced H2O2 production and the H 2O 2-activated Ca2-activated channels are important mechanisms for A BA-induced stomatal closing.

TL;DR: It is proposed that the oxidative stress syndrome would be more usefully described as 'oxidative signalling', that is, an important and critical function associated with the mechanisms by which plant cells sense the environment and make appropriate adjustments to gene expression, metabolism and physiology.

NADPH oxidase AtrbohD and AtrbohF genes function in ROS‐dependent ABA signaling in Arabidopsis

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.
