“…As well as the key influence of the GSH=GSSG ratio, the glutathione redox potential is modulated by total glutathione concentration. Genetic and other evidence shows that glutathione concentration is important in meristem function, light signaling, and pathogen responses (25,96,128,228,263,314,346,415,423). Within the context of plant responses to pathogens it has been shown that both the cytosolic regulatory protein, NPR1, and the specific TGA-type transcription factors with which NPR1 interacts, are controlled by disulfide reduction (84,280).…”

Reactive oxygen species (ROS) have multifaceted roles in the orchestration of plant gene expression and gene-product regulation. Cellular redox homeostasis is considered to be an "integrator" of information from metabolism and the environment controlling plant growth and acclimation responses, as well as cell suicide events. The different ROS forms influence gene expression in specific and sometimes antagonistic ways. Low molecular antioxidants (e.g., ascorbate, glutathione) serve not only to limit the lifetime of the ROS signals but also to participate in an extensive range of other redox signaling and regulatory functions. In contrast to the low molecular weight antioxidants, the "redox" states of components involved in photosynthesis such as plastoquinone show rapid and often transient shifts in response to changes in light and other environmental signals. Whereas both types of "redox regulation" are intimately linked through the thioredoxin, peroxiredoxin, and pyridine nucleotide pools, they also act independently of each other to achieve overall energy balance between energy-producing and energy-utilizing pathways. This review focuses on current knowledge of the pathways of redox regulation, with discussion of the somewhat juxtaposed hypotheses of "oxidative damage" versus "oxidative signaling," within the wider context of physiological function, from plant cell biology to potential applications.

“…The inhibitory effect of SA on radicle growth did not appear if SA application started at germination, suggesting that seedlings may become acclimated to SA (Kang and Saltveit, 2002). Treatment of wheat seeds with SA before sowing also stimulated the growth of plant shoots and roots, as evident from the increase in both their weights and lengths (Rakhmankulova et al, 2010). This effect was accompanied by a considerable decrease in the content of endogenous SA, especially its free active form and particularly in the shoots, and a gradual increase in the proportion of the alternative cyanide-resistant respiration pathway and a reduction in cytochrome respiration in the shoots.…”

Low temperature is one of the most important limiting factors for plant growth throughout the world. Exposure to low temperature may cause various phenotypic and physiological symptoms, and may result in oxidative stress, leading to loss of membrane integrity and to the impairment of photosynthesis and general metabolic processes. Salicylic acid (SA), a phenolic compound produced by a wide range of plant species, may participate in many physiological and metabolic reactions in plants. It has been shown that exogenous SA may provide protection against low temperature injury in various plant species, while various stress factors may also modify the synthesis and metabolism of SA. In the present review, recent results on the effects of SA and related compounds in processes leading to acclimation to low temperatures will be discussed.

“…It is worthy of note that, in roots, SA content and its dynamic during development may differ from that in shoots [5][6][7][8], which can potentially cause differences in SA functions. For instance, SA basal level in shoots is 2-100 times higher than in roots, depending on the species [5,6]. The ratio between free and conjugated SA forms, also differs [6].…”

In plants, salicylic acid (SA) is a hormone that mediates a plant’s defense against pathogens. SA also takes an active role in a plant’s response to various abiotic stresses, including chilling, drought, salinity, and heavy metals. In addition, in recent years, numerous studies have confirmed the important role of SA in plant morphogenesis. In this review, we summarize data on changes in root morphology following SA treatments under both normal and stress conditions. Finally, we provide evidence for the role of SA in maintaining the balance between stress responses and morphogenesis in plant development, and also for the presence of SA crosstalk with other plant hormones during this process.
