“…Salicylic acid maintained high root vigor, inhibited water loss, and maintained the integrity of cell structure by regulating osmotic substance content. Salicylic acid decreased the production of reactive oxygen species, increased the activity of protective enzymes, and the concentration of non-enzymatic reactive oxygen species scavengers (20). Also, our work was in the same line with the literature by (34)(35)(36)(37)(38).…”

“…Plant biostimulants are substances and materials, except nutrients and pesticides, which, when applied to plant, seeds, or growing substrates in specific formulations, can modify the physiological processes of plants in a way that provides potential benefits to growth, development and stress responses (14). Based on the preceding literature, the biostimulants such as salicylic acid and blue green algae extract of Spirulina platensis are observed to lessen heat stress on plants and contribute to rising yield (15)(16)(17)(18)(19)(20).…”

Increasing temperature is a global issue due to the existing climate change problem that reduces agricultural productivity and increases prices. It badly affects the yield, and active constituents of medicinal and aromatic plants, especially in newly reclaimed lands in desert areas. The Hibiscus sabdariffa L. is a remarkable crop known for its calyces to make a refreshing drink. It is in other food industries and has many healing effects. A split-plot field experiment was conducted on Hibiscus sabdariffa L. at Siwa Oasis, Egypt, during the 2018 and 2019 seasons for studying to reduce the harmful effect of heat stress on plants and yield improvement. Spraying with three salicylic acid concentrations was put to main plots as 0, 500, and 1000 mg/l and the number of sprays with Spirulina platensis algae extract was allotted to sub-plots and used as 0, 1 and 2 times in the season. Some quantity and quality parameters were under investigation. The significant highest increases in dry weight per plant, number of fruits per plant, dry yield of sepals per hectare and sepal's anthocyanin content were from the combination among spraying with salicylic acid at the concentration of 500 mg/l and spraying with blue green algae extract twice through the season. This treatment was helpful to decrease the high-temperature injury on growth through the summer months.

“…Recently, Cingoz and Gurel (2016) reported that exogenous application of SA (0.15 mM) significantly boosted the accumulation of cardenolide, enzymatic and non-enzymatic antioxidants that compellingly inhibited the adverse effect of heat stress on Digitalis trojana plants. Similarly, Zhang et al (2020b) have also confirmed the stimulatory growth role of SA applied at different concentrations in Capsicum annum plants exposed to high-temperature stress. In another study, Wassie et al (2020) reported that treating Medicago sativa plants with varying concentrations of SA ameliorates heat-stress-induced oxidative damage by improving growth, photosynthetic efficiency, and modulating defense expression responsive genes.…”

Salicylic Acid and Nitric Oxide: Insight Into the Transcriptional Regulation of Their Metabolism and Regulatory Functions in Plants

Salicylic acid (SA) and nitric oxide (NO) are key signaling molecules required to activate the plant's innate immunity against abiotic stresses and biotrophic attackers. Stress-induced signaling and accumulation of SA and NO triggers extensive transcriptional reprogramming of defense-related genes, induced biosynthesis of secondary metabolites and anti-microbial compounds, thereby protecting/steering plant growth and immunity. Transcriptional regulation of SA and NO signaling are crucial for fine-tuning important cellular and metabolic functions, thus making plant defense impervious against many pathogens. The development of an impenetrable immune response is often associated with an unavoidable trade-off in the form of active suppression of plant growth and reproduction. Therefore, we highlighted recent advancements and research to unravel transcriptional regulation of SA and NO signaling essential for fulfilling their role as defense signaling molecules. We also emphasized comprehensive knowledge related to transcriptional reprogramming of SA and NO signaling important in strengthening plant growth-immunity trade-off. We also highlighted the progress on SA and NO signaling playing an indispensable role in stimulating plant-microbe interaction to modulate crucial plant functions.

“…The MDA content of maize seedlings was reduced under heat stress due to the foliar spray of SA [45]. Declined MDA content was also reported by Zhang et al [46] in ornamental pepper by SA foliar spray under heat stress. This could be credited to an enhanced antioxidant defense system and alleviated heat stress-induced membrane damage.…”

In the present era of climate change and global warming, high temperatures have increased considerably, posing a threat to plant life. Heat stress affects the biochemistry, physiology and molecular makeup of the plant by altering the key processes, i.e., photosynthesis, respiration and reproduction which reduces its growth and development. There is a dire need to manage this problem sustainably for plant conservation as well as the food security of the human population. Use of phytohormones to induce thermotolerance in plants can be a sustainable way to fight the adversities of heat stress. Phytohormone-induced thermotolerance proves to be a compelling approach to sustainably relieve the damaging effects of heat stress on plants. Salicylic acid (SA) is an essential molecule in biotic and abiotic defense response signal transduction pathways. When supplied externally, it imparts heat stress tolerance to the plants by different means, viz., increased Heat Shock Proteins (HSP) production, Reactive oxygen species (ROS) scavenging, protection of the reproductive system and enhancing photosynthetic efficiency. The effect of SA on plants is highly dependent on the concentration applied, plant species, plant age, type of tissues treated, and duration of the treatment. The present review paper summarizes the mechanism of thermotolerance induced by salicylic acid in plants under heat stress conditions. It includes the regulatory effects of SA on heat shock proteins, antioxidant metabolism, and maintenance of Ca 2+ homeostasis under heat stress. This review combines the studies conducted to elucidate the role of SA in the modulation of different mechanisms which lead to heat stress tolerance in plants. It discusses the mechanism of SA in protecting the photosynthetic machinery and reproductive system during high-temperature stress.
