“…For example, PLDα1 must be activated downstream of SA6061 and PLDα1-PA regulates ABA signalling62. Interestingly, PLDα1 was downregulated at the protein level in infected GC plants compared to infected wild-type plants, creating a possible link between the modulation of PLD by cGMP and a phytohormone imbalance that blocks SAR.…”

The infection of Arabidopsis thaliana plants with avirulent pathogens causes the accumulation of cGMP with a biphasic profile downstream of nitric oxide signalling. However, plant enzymes that modulate cGMP levels have yet to be identified, so we generated transgenic A. thaliana plants expressing the rat soluble guanylate cyclase (GC) to increase genetically the level of cGMP and to study the function of cGMP in plant defence responses. Once confirmed that cGMP levels were higher in the GC transgenic lines than in wild-type controls, the GC transgenic plants were then challenged with bacterial pathogens and their defence responses were characterized. Although local resistance was similar in the GC transgenic and wild-type lines, differences in the redox state suggested potential cross-talk between cGMP and the glutathione redox system. Furthermore, large-scale transcriptomic and proteomic analysis highlighted the significant modulation of both gene expression and protein abundance at the infection site, inhibiting the establishment of systemic acquired resistance. Our data indicate that cGMP plays a key role in local responses controlling the induction of systemic acquired resistance in plants challenged with avirulent pathogens.

“…These findings point out that SA induces stomatal closure along with extracellular ROS generation mediated by SHAM-sensitive peroxidase, intracellular ROS accumulation and inactivation of K + in channels [41]. In contrary to this, Kalachova et al [53], reported that SA-induced stomatal closure is impaired by DPI [an NADPH oxidases (NOX) inhibitor that inhibits ROS production] treatment and NOX deficient plants showed inhibited stomatal reaction even after exposure to exogenous SA [53]. Thus, it can be concluded that NOX plays a critical role in stomatal closure in response to SA also.…”

Reactive oxygen species signaling and stomatal movement: Current updates and future perspectives

Reactive oxygen species (ROS), a by-product of aerobic metabolism were initially studied in context to their damaging effect but recent decades witnessed significant advancements in understanding the role of ROS as signaling molecules. Contrary to earlier views, it is becoming evident that ROS production is not necessarily a symptom of cellular dysfunction but it might represent a necessary signal in adjusting the cellular machinery according to the altered conditions. Stomatal movement is controlled by multifaceted signaling network in response to endogenous and environmental signals. Furthermore, the stomatal aperture is regulated by a coordinated action of signaling proteins, ROS-generating enzymes, and downstream executors like transporters, ion pumps, plasma membrane channels, which control the turgor pressure of the guard cell. The earliest hallmarks of stomatal closure are ROS accumulation in the apoplast and chloroplasts and thereafter, there is a successive increase in cytoplasmic Ca2+ level which rules the multiple kinases activity that in turn regulates the activity of ROS-generating enzymes and various ion channels. In addition, ROS also regulate the action of multiple proteins directly by oxidative post translational modifications to adjust guard cell signaling. Notwithstanding, an active progress has been made with ROS signaling mechanism but the regulatory action for ROS signaling processes in stomatal movement is still fragmentary. Therefore, keeping in view the above facts, in this mini review the basic concepts and role of ROS signaling in the stomatal movement have been presented comprehensively along with recent highlights.

“…Contrary to this, a recent study demonstrated that SA does make use of the NADPH oxidase. After treatment of exogenous SA, stomatal closure showed 200 % decrease compared to a 10 % decrease in stomatal aperture by the NADPH oxidase mutant rbohD (Kalachova et al 2013 ).…”

Elucidation of Abiotic Stress Signaling in Plants

Biotic and abiotic stresses are signifi cant factors limiting the production of food and other supporting materials required to sustain increasing world population. Plant health is directly related to human health and is increasingly becoming signifi cant and demands more attention towards limiting the damages caused by biotic and abiotic stresses. Signifi cant progress has been made towards our understanding of the processes, which mediate both biotic and abiotic stress signaling in plants. Signifi cant role is played by various plant hormones, e.g., salicylic acid (SA) and jasmonic acid (JA) in biotic stress and abscisic acid (ABA) in abiotic stress (Annu Rev Cell Dev Biol 28:489-521, 2012). Other hormones with minor role include the cytokinins (CK), auxins (indole 3 acetic acid. IAA), and the brassinosteroids (BR) (Annu Rev Cell Dev Biol 28:489-521, 2012). Cross talk between these plant hormones is signifi cant and may result in either synergistic or antagonistic effect on stress responses (Annu Rev Cell Dev Biol 28:489-521, 2012). In recent years, extensive research carried out in various laboratories has implicated cross talk between the ABA and the SA in abiotic stress response. This is signifi cant in light of SA being key player in biotic stress responses in plants. This review will discuss the role of SA in biotic and abiotic stress signaling and its cross talk with other hormones in mediating abiotic stress signaling in plants.
