“…SA, JA, and BR are molecules that are involved in several plant physiological processes [47][48][49]. For example, SA is involved in leaf gas exchange (photosynthesis rate, stomatal conductance), water relations, and modulates plant response to environmental stress [50].…”

Vascular wilt caused by Fusarium oxysporum is the most limiting disease that affects cape gooseberry (Physalis peruviana L.) crops in Colombia. The use of synthetic elicitors for vascular wilt management is still scarce in Andean fruit species. The objective of the present study was to evaluate the effect and number of foliar applications of synthetic elicitors such as jasmonic acid (JA), salicylic acid (SA), brassinosteroids (BR), or a commercial resistance elicitor based on botanical extracts (BE) on disease progress and their effect on the physiology of cape gooseberry plants inoculated with F. oxysporum f. sp. physali. Groups of ten plants were separately sprayed once, twice, or three times with a foliar synthetic elicitor, respectively. Elicitor applications were performed at the following concentrations: JA (10 mL L−1), SA (100 mg L−1), BR (1 mL L−1) and BE (2.5 mL of commercial product (Loker®) L−1). The results showed that three foliar BR, SA, or BE applications reduced the area under the disease progress, severity index, and vascular browning in comparison to inoculated plants without any elicitor spray. Three BR, SA, or BE sprays also favored stomatal conductance, water potential, growth (total dry weight and leaf area) and fluorescence parameters of chlorophyll compared with inoculated and untreated plants with no elicitor sprays. Three foliar sprays of SA, BR, or BE enhanced photosynthetic pigments (leaf total chlorophyll and carotenoid content) and proline synthesis and decreased oxidative stress in Foph-inoculated plants. In addition, the effectiveness of three foliar BR, SA, or BE sprays was corroborated by three-dimensional plot and biplot analysis, in which it can evidence that stomatal conductance, proline synthesis, and efficacy percentage were accurate parameters to predict Foph management. On the hand, JA showed the lowest level of amelioration of the negative effects of Foph inoculation. In conclusion, the use of the synthetic elicitors BR, SA, or BE can be considered as a tool complementary for the commercial management of vascular wilt in areas where this disease is a limiting factor.

“…Salicylic acid (SA), which corresponds to 2‐hydroxybenzoic acid (compound 1 in Fig. ) is a phenolic compound produced by plants, involved in numerous physiological processes, such as signalization, stomatal closure, seed germination, flowering, and senescence . SA is known as a phytohormone that triggers plant immune responses and its endogenous accumulation is required for the expression of the systemic acquired resistance .…”

Further investigations are needed to identify the defence pathways involved in plant resistance mechanisms elicited or primed by the molecules. The manufacture of these products was easily achieved on a scale of tens of grams of raw materials, and is easily scalable. The synthetic pathway is simple, short and inexpensive. For all of these reasons, the production of the target molecules is attractive for producers, whereas the prospect of a generation of non-polluting compounds with lasting efficiency against Z. tritici in wheat comes at a key moment for the sustainability of agriculture. © 2018 Society of Chemical Industry.

“…Thus, for example, pathogen influence on plants leads to SA excretion into the apoplast and further transport into the plant (Alvarez, 2000). SA influences plant growth and development (Yusuf et al 2013), and stimulates the systemic acquired resistance (SAR) of plants to various pathogens (van Loon 2007;Barba-Espin et al 2010;Rivas-San & Plasencia 2011). This work is devoted to studying SA influence on the interaction of wheat calli with bunt (T. caries) and smut (U. tritici) pathogenic agents. Development of the defense reactions of the host immune system connected with the activity of peroxidase and accumulation of H 2 O 2 was discovered.…”

The role of salicylic acid (SA) in regulating wheat calli growth and peroxidase activity in the co-culture with bunt (Tilletia caries (D.C.) Tul.) and smut (Ustilago tritici Pers.) pathogens was studied in this work. We found that the influence of SA increased the number of globular high-density sites with meristema-like cells and reduced the number of low-structured sites with parenchyma-like cells in wheat calli. SA inhibited fungi spores germination, mycelium growth, and formation of its new spores during the co-cultivation of wheat calli with bunt or smut agent. Interaction of fungi mycelium with wheat calli treated by SA led to formation of zones with hypersensitive reaction in calli high-structured sites with meristema-like cells. The obtained data about the influence of SA on activation of wheat calli growth and the peroxidases with pI Â3.5 and Â9.8, which can bind to the mycelium of T. caries or U. tritici are discussed in this paper.
