Drought and salinity are among the most important abiotic stress factors. Although there is a growing interest to the sustainability of fruit growing in arid and salty areas, there are not enough studies. Therefore, this study was carried out for the determination of the effects of harpin protein at different salt concentrations in Pistachio (Pistacia vera L.) seeds. At the end of the treatment, there was a 20% decrease in plant height, 43% in root length, and approximately 40% in fresh and dry plant weight. Superoxide dismutase, catalase and ascorbate peroxidase antioxidant enzyme activities increased by 171%, 285% and 390%, respectively. In addition, the amount of chlorophyll a, chlorophyll b, and chlorophyll a+b (respetctively, 47%, 42%, 43%) was decrease. In addition, it was determined that harpin applications protected the chlorophyll content related to photosynthesis, increased the diameter of the stem and root and decreased the stress enzyme activities. Thus, applications of harpin protein may be beneficial to increase tolerance to drought/salinity stresses in pistachio plants, especially in the early stages of seedling development. These findings may pave the way for future research on stress management in sustainable fruit growing in arid and semi-arid areas.

“…This harpin-promoted growth may have been related to an increase in photosynthesis due to increased chlorophyll levels, CO 2 conduction rates, and greater changes in the levels of phytohormones, e.g., ethylene (ET), gibberellin (GA), and salicylic acid (SA) [ 14 , 18 , 26 , 27 , 31 , 53 ]. Notably, exogenous PopW (a harpin from Ralstonia solanacearum ZJ3721) treatment led to greater drought resistance in Medicago sativa L. and tomato, and this effect was related to multiple mechanisms, such as the action of phytohormones, e.g., abscisic acid (ABA), GA, SA, and drought-related gene expression [ 15 , 52 ].…”

“…According to their chemical properties, elicitors can be classified into proteinaceous, carbohydrate, chemical-inducing elicitors, and so on. Exogenous proteinaceous elicitors are proteinaceous elicitors from microorganisms, especially pathogens, and they are involved in many processes, such as the virulence of pathogens, abiotic stresses and biotic stresses in plants [ 11 , 12 , 13 , 14 , 15 ]. Although many studies and reviews have focused their attention on the involvement of proteinaceous elicitors in plant innate immunity and abiotic stresses in past decades, there is a lack of up-to-date reviews on the characteristics and functions of proteinaceous elicitors.…”

In interactions between pathogens and plants, pathogens secrete many molecules that facilitate plant infection, and some of these compounds are recognized by plant pattern recognition receptors (PRRs), which induce immune responses. Molecules in both pathogens and plants that trigger immune responses in plants are termed elicitors. On the basis of their chemical content, elicitors can be classified into carbohydrates, lipopeptides, proteinaceous compounds and other types. Although many studies have focused on the involvement of elicitors in plants, especially on pathophysiological changes induced by elicitors in plants and the mechanisms mediating these changes, there is a lack of up-to-date reviews on the characteristics and functions of proteinaceous elicitors. In this mini-review, we provide an overview of the up-to-date knowledge on several important families of pathogenic proteinaceous elicitors (i.e., harpins, necrosis- and ethylene-inducing peptide 1 (nep1)-like proteins (NLPs) and elicitins), focusing mainly on their structures, characteristics and effects on plants, specifically on their roles in plant immune responses. A solid understanding of elicitors may be helpful to decrease the use of agrochemicals in agriculture and gardening, generate more resistant germplasms and increase crop yields.

“…Under drought stress conditions, accumulation of the hormone abscisic acid (ABA) plays an important role in response and tolerance to dehydration. ABA causes the closure of stomata and induces the expression of multiple genes involved in defence against drought stress (Zhou et al 2020). Plants also activate the production of non-enzymatic and enzymatic antioxidants.…”

Climate change and global warming are leading to severe drought stress, causing damage to crops in different regions of the world. Drought stress is an abiotic stress that interferes with major metabolic pathways, influencing mainly morphological, physiological and biochemical parameters of plants, ultimately resulting in decreased growth and yield of crops. Plants should be able to utilise available moisture efficiently, and there is a need to focus on organic and eco-friendly methods for improving crops facing drought stress. A practical approach for enhancing growth and development under stressful conditions is the application of plant growth promoting rhizobacteria (PGPR), soil microbes that help plants to cope with extreme ecological conditions. This review aims to highlight the function of various PGPR metabolites that help to mitigate water-deficit conditions. These microbes exist naturally in the rhizosphere of plants, and they enhance plant growth by several direct mechanisms such as aminocyclopropane-1-carboxylate deaminase and osmolyte production, secretion of exopolysaccharides and phytohormones, triggering of antioxidant defence mechanisms against reactive oxygen species and production of volatile organic compounds, as well as by indirect mechanisms including enhancing induced systemic resistance and pathogen suppression. This review recommends the use of PGPR for improving growth and development of crops under drought stress and supports their role as effective and sustainable bioinoculants for enhancing the growth and production of crops.
