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:

Plant signaling networks involving Ca2+ and Rboh/Nox-mediated ROS production under salinity stress
TL;DR: Molecular identity, structural features and roles of the Ca2-permeable channels involved in early salinity and osmotic signaling, and the interrelationships among spatiotemporal dynamic changes in cytosolic concentrations of free Ca2+, Rboh-mediated ROS production, and downstream signaling events during salinity adaptation in planta are reviewed.
Journal ArticleDOI
Molecular mechanisms involved in plant adaptation to low K+ availability
TL;DR: This review is focused on the different physiological responses induced by K(+) deprivation, their underlying molecular events, and the present knowledge and hypotheses regarding the mechanisms responsible for K(+ sensing and signalling.

Coordinating the overall stomatal response of plants: Rapid leaf-to-leaf communication during light stress
TL;DR: It is found that different leaves within the canopy of an Arabidopsis thaliana plant, including leaves not directly exposed to light, coordinated stomatal closure in response to light stress by sending and receiving rapid systemic signals.
Journal ArticleDOI
Calcium-Mediated Abiotic Stress Signaling in Roots
TL;DR: Progress is addressed in identifying the calcium transporting proteins that effect stress-induced calcium increases in roots and links to reactive oxygen species, lipid signaling, and the unfolded protein response are explored.

Genomic Libraries and a Host Strain Designed for Highly Efficient Two-Hybrid Selection in Yeast
TL;DR: A novel multienzyme approach was used to generate a set of highly representative genomic libraries from S. cerevisiae and a unique host strain was created that contains three easily assayed reporter genes, each under the control of a different inducible promoter.

ROS signaling: the new wave?
Ron Mittler,Ron Mittler,Sandy Vanderauwera,Nobuhiro Suzuki,Gad Miller,Vanesa B. Tognetti,Klaas Vandepoele,Marty Gollery,Vladimir Shulaev,Frank Van Breusegem +9 more
TL;DR: This review will attempt to address several key questions related to the use of ROS as signaling molecules in cells, including the dynamics and specificity of ROS signaling, networking of ROS with other signaling pathways, ROS signaling within and across different cells, ROS waves and the evolution of the ROS gene network.

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.

Arabidopsis gp91phox homologues AtrbohD and AtrbohF are required for accumulation of reactive oxygen intermediates in the plant defense response
TL;DR: In this paper, the authors analyzed lines carrying dSpm insertions in the highly expressed AtrbohD and AtrabohF genes, which are required for full ROI production observed during incompatible interactions with the bacterial pathogen Pseudomonas syringae pv.
