Rapid, long-distance signaling in plants A plant injured on one leaf by a nibbling insect can alert its other leaves to begin anticipatory defense responses. Working in the model plant Arabidopsis, Toyota et al. show that this systemic signal begins with the release of glutamate, which is perceived by glutamate receptor–like ion channels (see the Perspective by Muday and Brown-Harding). The ion channels then set off a cascade of changes in calcium ion concentration that propagate through the… 
Nervous system-like signaling in plant defense
TLDR
Long-distance calcium ion signaling in the model plant Arabidopsis thaliana is uncovered that requires glutamate-like receptor (GLR) channels for signal propagation, which is an intriguing parallel to their role as long-distance signals in wounding and defense in plants.
The Fast and The Furious: Rapid long-range signaling in plants.
TLDR
A communication system acting through the transmission of electrical, Ca2+, reactive oxygen species and potentially even hydraulic signals has been discovered that can propagate signals across many cells each second and researchers are now beginning to uncover the molecular machineries behind this rapid communications network.
Crosstalk between Calcium and ROS Signaling during Flg22-Triggered Immune Response in Arabidopsis Leaves
TLDR
The data suggest that cytosolic calcium elevation is required to initiate and regulate apoplastic ROS production generated by respiratory burst oxidase homologs (RBOHs) and is required for forming a sufficient amplitude of the calcium signal.
Plant Immune Memory in Systemic Tissue Does Not Involve Changes in Rapid Calcium Signaling
TLDR
Comparisons of flg22-induced cytoplasmic calcium changes in Arabidopsis wild-type, cpk5 mutant and CPK5-overexpressing plants are compared by introgressing the calcium indicator R-GECO1-mTurquoise that allows internal normalization through m Turquoise fluorescence to indicate that the mechanistic manifestation of a plant immune memory in distal plant parts required for enhanced pathogen resistance relies on downstream defense responses.
Plasmodesmata-localized proteins and reactive oxygen species orchestrate light-induced rapid systemic signaling in Arabidopsis
Systemic signaling and systemic acquired acclimation (SAA) are key to the survival of plants during episodes of abiotic stress. These processes depend on a continuous chain of cell-to-cell signaling
Two glutamate- and pH-regulated Ca2+ channels are required for systemic wound signaling in Arabidopsis
TLDR
It is found that root wounding or the application of glutamate to wounded roots was sufficient to trigger root-to-shoot Ca2+ waves and slow wave potentials (SWPs), which support the hypothesis that wounding inhibits P-type H+-ATPase activity, leading to apoplastic alkalization.
Integration of electric, calcium, reactive oxygen species and hydraulic signals during rapid systemic signaling in plants
TLDR
It is revealed that hydraulic waves can be actively regulated in plants in response to wounding, and that proteins that regulate plasmodesmata pores play a key role in systemic signaling.
Early Extracellular ATP Signaling in Arabidopsis Root Epidermis: A Multi-Conductance Process
Adenosine 5′-triphosphate (ATP) is an important extracellular signaling agent, operating in growth regulation, stomatal conductance, and wound response. With the first receptor for extracellular ATP
Noxious effects of cell surface display glutamate sensors on plant growth and development
TLDR
Overall, data indicate sensor noxiousness was dependent on its membrane-tethering and likely caused by sequestration of extracellular glutamate, specifically at the cell surface, thereby either disrupting the supply of glutamate to meristematic cells and/or by impairing local glutamatergic signaling during development.

Orchestrating rapid long-distance signaling in plants with Ca2+ , ROS and electrical signals.
TLDR
Regardless of how signals move from cell to cell, they help prepare distant parts of the plant for impending challenges from specific biotic or abiotic stresses.
Salt stress-induced Ca2+ waves are associated with rapid, long-distance root-to-shoot signaling in plants
TLDR
Plants possess a rapid stress signaling system based on Ca2+ waves that propagate through the plant at rates of up to ∼400 µm/s, and this system likely elicits systemic molecular responses in target organs and may contribute to whole-plant stress tolerance.
GLUTAMATE RECEPTOR-LIKE genes mediate leaf-to-leaf wound signalling
TLDR
This work provides a genetic basis for investigating mechanisms of long-distance wound signalling in plants and indicates that plant genes related to those important for synaptic activity in animals function in organ-to-organ wound signalling.
Glutamate receptor-like channels in plants: a role as amino acid sensors in plant defence?
TLDR
Evidence that some members of clade 3 of the GLR gene family encode important components of the plant's defence response is provided, which opens up the possibility that GLR receptors could have a pervasive role in plants as non-specific amino acid sensors in diverse biological processes.
Interacting Glutamate Receptor-Like Proteins in Phloem Regulate Lateral Root Initiation in Arabidopsis[W][OA]
TLDR
Evidence is provided of an interaction between two types of Glu receptor proteins that allow entry of calcium ions into the cytoplasm when activated by an amino acid that support the hypothesis that apoplastic amino acids acting through heteromeric GLR3.4 channels affect lateral root development via Ca2+ signaling in the phloem.
The squeeze cell hypothesis for the activation of jasmonate synthesis in response to wounding.
TLDR
A model in which rapid axial changes in xylem hydrostatic pressure caused by wounding travel through the vasculature and lead to slower,radially dispersed pressure changes that act in a clade 3 GLR-dependent mechanism to promote distal jasmonate synthesis is proposed.

TLDR
Experimental evidence is presented showing that the Arabidopsis thaliana plasmodesmata-located protein 5 (PDLP5) mediates crosstalk between PD regulation and salicylic acid–dependent defense responses, and a model is proposed illustrating that the regulation of PD closure mediated by PDLP5 constitutes a crucial part of coordinated control of cell-to-cell communication and defense signaling.

TLDR
Wound-induced systemic production of JA-Ile required the JA biosynthetic enzyme 12-oxo-phytodienoic acid (OPDA) reductase 3 (OPR3) in undamaged responding leaves, but not in wounded leaves, and was largely dependent on the JA-conjugating enzyme JAR1.
