“…It has the potential to improve cell prolifera- tion, senescence gene expression, and fruit output (Klessig et al 2009;Kazem et al 2020;Rao et al 2021). Salicylic acid is crucial for enhancing environmental stress resistance (Raskin 1992;Liu et al 2022) such as salinity tolerance (Jam et al 2012;Farhangi-Abriz and Ghassemi-Golezani 2018;Hongna et al 2021;Hamayun et al 2022;Kumar et al 2022), water-deficit tolerance (Bezaukova et al 2001;Lee et al 2019;Abbaszadeh et al 2020;Ahmad et al 2021;Khalvandi et al 2021;Safari et al 2021;Shemi et al 2021), and low and high temperature tolerance (Khan et al 2010;Ignatenko et al 2019;Afzal et al 2020;Wassie et al 2020;Yang et al 2022). Similarly, SA plays a role in plant physiological activities such as stomatal control, food uptake, chlorophyll and protein synthesis, ethylene biosynthesis inhibition, and photosynthesis (Raskin 1992;Cheng et al 2016;Jahan et al 2019).…”

Common beans are very significant for poor countries, because they provide high nutritional value, especially in terms of protein, calories, and trace nutrients, to people who cannot afford more expensive forms of nourishment. The current experiment was performed to investigate the influence of four different levels of organic fertilizer (compost) in the presence of mineral N fertilizer, i.e., T1: 25% M‑RDN +75% O‑RDN; T2: 50% M‑RDN +50% O‑RDN; T3: 75% M‑RDN +25% O‑RDN; and T4 (control): 100% M‑RDN (O-RDN, M‑RDN = recommended dose of N in organic and mineral forms, respectively; RDN: 60 kg N/fed.) and foliar spray with salicylic acid (SA) at 0, 50, 100, and 150 ppm, as well as of their interaction, on vegetative growth, productivity, and seed quality of common bean (Phaseolus vulgaris L.) cv. Nebraska. Obtained results showed that the tallest plants, the highest number of branches per plant, and the heaviest leaf fresh and dry weight per plant were scored using the combined treatment comprising T4 (100% M‑RDN) and SA at 150 ppm in the two seasons. T4-fertilized and 150 ppm SA-sprayed plants induced the highest values of leaf N, P, K, and total carbohydrates (%). The highest seed yield per plant and hectare as well as the highest average weight of 100 seeds were achieved by plants fertilized with T4 or T3 treatments (75% of M‑RDN +25% O‑RDN) and sprayed with 150 ppm SA in the two seasons. The combined treatment of T4 and SA at 150 ppm caused the statistically highest values of seed N%, P%, total protein (%), K%, and total carbohydrate (%). In addition, the lowest values of seed nitrate content were achieved by plants fertilized with the T1 treatment (25% M‑RDN +75% O‑RDN) and receiving 150 ppm SA foliar spray. In conclusion, for enhanced growth, productivity, and quality of common bean plants, it could be safe to fertilize with 75% M‑RDN +25% M‑RDN and spray these plants with SA at 150 ppm.

“…The phytohormone SA has been considered an 'effective therapeutic agent' for plants due to its role in regulating physiological and biochemical processes under multiple abiotic stresses, including cold, drought, heat, heavy metal toxicity •− , H 2 O 2 , MDA, SOD (superoxide dismutase), CAT, APX, POD, GPX and Pro (proline). Control, Drought, Drought+SA1, Drought+SA2, and Drought+SA3 represent 80% SMC, 7.5% SMC, 7.5% SMC t + 0.5 mM SA, 7.5% SMC + 1.0 mM SA and 7.5% SMC + 1.5 mM SA, respectively and osmotic stress [39][40][41]. In the current study, we examined the beneficial effects of SA in alleviating the negative consequences of drought effects on barley plants.…”

Drought is a severe environmental constraint, causing a significant reduction in crop productivity across the world. Salicylic acid (SA) is an important plant growth regulator that helps plants cope with the adverse effects induced by various abiotic stresses. The current study investigated the potential effects of SA on drought tolerance efficacy in two barley (Hordeum vulgare) genotypes, namely BARI barley 5 and BARI barley 7. Ten-day-old barley seedlings were exposed to drought stress by maintaining 7.5% soil moisture content in the absence or presence of 0.5, 1.0 and 1.5 mM SA. Drought exposure led to severe damage to both genotypes, as indicated by phenotypic aberrations and reduction of dry biomass. On the other hand, the application of SA to drought-stressed plants protected both barley genotypes from the adverse effects of drought, which was reflected in the improvement of phenotypes and biomass production. SA supplementation improved relative water content and proline levels in drought-stressed barley genotypes, indicating the osmotic adjustment functions of SA under water-deficit conditions. Drought stress induced the accumulation of reactive oxygen species (ROS), such as hydrogen peroxide (H 2 O 2 ) and superoxide (O 2 •−), and the lipid peroxidation product malondialdehyde (MDA) in the leaves of barley plants. Exogenous supply of SA reduced oxidative damage by restricting the accumulation of ROS through the stimulation of the activities of key antioxidant enzymes, including superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbate peroxidase (APX) and glutathione peroxidase (GPX). Among the three-applied concentrations of SA, 0.5 mM SA exhibited better mitigating effects against drought stress considering the phenotypic performance and biochemical data. Furthermore, BARI barley 5 showed better performance under drought stress than BARI barley 7 in the presence of SA application. Collectively, our results suggest that SA played a crucial role in improving water status and antioxidant defense strategy to protect barley plants from the deleterious effects of water deficiency.

“…In addition to the involvement of salicylic acid in SAR, this hormone has been found to be involved in the mitigation of various plant abiotic stresses including both high and low temperature, high levels of salt, inhibition by high levels of metals, insufficient levels of oxygen, ozone, the presence of toxic organic chemicals, ultraviolet radiation, and drought [ 52 ]. For example, Aires and colleagues [ 53 ] applied SA to tomato leaves subjected to water stress and observed a favorable plant response by improving parameters such as CO 2 assimilation, transpiration, stomatal conductance, water use efficiency, and carboxylation efficiency.…”

Phytohormones are regulators of plant growth and development, which under different types of stress can play a fundamental role in a plant’s adaptation and survival. Some of these phytohormones such as cytokinin, gibberellin, salicylic acid, auxin, and ethylene are also produced by plant growth-promoting bacteria (PGPB). In addition, numerous volatile organic compounds are released by PGPB and, like bacterial phytohormones, modulate plant physiology and genetics. In the present work we review the basic functions of these bacterial phytohormones during their interaction with different plant species. Moreover, we discuss the most recent advances of the beneficial effects on plant growth of the phytohormones produced by PGPB. Finally, we review some aspects of the cross-link between phytohormone production and other plant growth promotion (PGP) mechanisms. This work highlights the most recent advances in the essential functions performed by bacterial phytohormones and their potential application in agricultural production.
