TLDR
A direct interconnection between CBL-CIPK-mediated Ca(2+) signaling and ROS signaling in plants is identified and evidence for a synergistic activation of the NADPH oxidase RBOHF is provided by directCa(2+)-binding to its EF-hands and Ca( 2+)-induced phosphorylation by CBL1/9-C IPK26 complexes.About:

Abiotic Stress Signaling and Responses in Plants
TL;DR: Core stress-signaling pathways involve protein kinases related to the yeast SNF1 and mammalian AMPK, suggesting that stress signaling in plants evolved from energy sensing.
Journal ArticleDOI
Reactive oxygen species, abiotic stress and stress combination.
TL;DR: ROS is beneficial to plants during abiotic stress enabling them to adjust their metabolism and mount a proper acclimation response, as long as cells maintain high enough energy reserves to detoxify ROS.
Journal ArticleDOI
ROS as key players in plant stress signalling
TL;DR: 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.

TL;DR: This study reveals a rapid regulatory mechanism of a plant RBOH, which occurs in parallel with and is essential for its paradigmatic calcium-based regulation.
Journal ArticleDOI
Hydrogen peroxide metabolism and functions in plants.
TL;DR: H2 O2 oxidizes specific cysteine residues of target proteins to the sulfenic acid form and, similar to other organisms, this modification could initiate thiol-based redox relays and modify target enzymes, receptor kinases and transcription factors.

Local positive feedback regulation determines cell shape in root hair cells.
TL;DR: This work found that Ca2+, in turn, activated the RHD2 NADPH oxidase to produce ROS at the growing point in the root hair.

TL;DR: Results imply that plasma membrane-localized CBL1- and CBL9-CIPK23 complexes simultaneously regulate K+ transport processes in roots and in stomatal guard cells.

TL;DR: In this paper, the N-terminal region of Rboh was found to contain two Ca2+ binding EF-hand motifs, and the results indicated that cytosolic Ca 2+ concentration may modulate NADPH oxidase activity by regulating the interaction between Rac GTPase and RBH.

A Ca2+ signaling pathway regulates a K+ channel for low-K response in Arabidopsis
TL;DR: It is shown that the protein kinase CIPK23 interacted with, and phosphorylated, a voltage-gated inward K+ channel (AKT1) required for K+ acquisition in Arabidopsis, confirming that the Ca2+-CBL-CIPK pathway functions to orchestrate transporting activities in planta according to external K+ availability.
