“…An egg‐induced increase of SA levels has also previously been shown in brassicaceous species (e.g., Bonnet et al, ; Hilfiker et al, ). Likewise, induction of SA levels by larval feeding were found in several previous studies (e.g., Bi, Murphy, & Felton, ; Heidel & Baldwin, ; Peng, Deng, Huang, Jia, & Miao, ; Rostás, Winter, Borkowski, & Zeier, ). We suggest that the slightly higher SA levels in egg‐deposited, feeding‐induced leaves than in egg‐free, feeding‐induced ones are due to dual induction by the eggs and onset of larval feeding.…”

“…Although the increase in the SA level in egg‐deposited, feeding‐damaged plants was just modest, the question comes up how an enhanced SA level is related to the impaired performance of larvae on previously egg‐deposited leaves? Numerous studies have shown antagonistic interactions between SA‐ and JA‐mediated plant responses (Erb, Meldau, & Howe, ; Pieterse et al, ; Pieterse, van der Does, Zamioudis, Leon‐Reyes, & van Wees, ; Thaler, Humphrey, & Whiteman, ), whereas only few revealed neutral or synergistic interactions (Hilfiker et al, ; Rostás et al, ; Rostás, Simon, & Hilker, ; Van Oosten et al, ).…”

Plants can improve their antiherbivore defence by taking insect egg deposition as cue of impending feeding damage. Previous studies showed that Pieris brassicae larvae feeding upon egg‐deposited Brassicaceae perform worse and gain less weight than larvae on egg‐free plants. We investigated how P. brassicae oviposition on Arabidopsis thaliana affects the plant's molecular and chemical responses to larvae. A transcriptome comparison of feeding‐damaged leaves without and with prior oviposition revealed about 200 differently expressed genes, including enhanced expression of PR5, which is involved in salicylic acid (SA)‐signalling. SA levels were induced by larval feeding to a slightly greater extent in egg‐deposited than egg‐free plants. The adverse effect of egg‐deposited wild‐type (WT) plants on larval weight was absent in an egg‐deposited PR5‐deficient mutant or other mutants impaired in SA‐mediated signalling, that is, sid2/ics1, ald1, and pad4. In contrast, the adverse effect of egg‐deposited WT plants on larvae was retained in egg‐deposited npr1 and wrky70 mutants impaired further downstream in SA‐signalling. Oviposition induced accumulation of flavonols in WT plants with and without feeding damage, but not in the PR5‐deficient mutant. We demonstrated that egg‐mediated improvement of A. thaliana's antiherbivore defence involves SA‐signalling in an NPR1‐independent manner and is associated with accumulation of flavonols.

“…However, nonantagonistic interaction between SA and JA are also reported, but an exact mechanism is still unclear and it needs further studies [186]. For example, in maize plants Cu stress induced the biosynthesis of SA, which further induced JA priming and JA induced volatile organic compounds [189,190].…”

The Role of Salicylic Acid in Plants Exposed to Heavy Metals

Salicylic acid (SA) is a very simple phenolic compound (a C7H6O3 compound composed of an aromatic ring, one carboxylic and a hydroxyl group) and this simplicity contrasts with its high versatility and the involvement of SA in several plant processes either in optimal conditions or in plants facing environmental cues, including heavy metal (HM) stress. Nowadays, a huge body of evidence has unveiled that SA plays a pivotal role as plant growth regulator and influences intra- and inter-plant communication attributable to its methyl ester form, methyl salicylate, which is highly volatile. Under stress, including HM stress, SA interacts with other plant hormones (e.g., auxins, abscisic acid, gibberellin) and promotes the stimulation of antioxidant compounds and enzymes thereby alerting HM-treated plants and helping in counteracting HM stress. The present literature survey reviews recent literature concerning the roles of SA in plants suffering from HM stress with the aim of providing a comprehensive picture about SA and HM, in order to orientate the direction of future research on this topic.

“…Moreover, most scientists confirm the JA-SA antagonistic interaction (Zhang et al 2017). But in Z. mays plants attacked by caterpillars, no antagonistic crosstalk between the JA and SA pathways was stated (Rostás et al 2013). On the other hand, it was proved that the elevated levels of SA in Cu treated maize plants were directly responsible for JA induction (Engelberth et al 2011).…”

The activities of antioxidative enzymes, i.e. superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and guaiacol peroxidase (GPX), in the leaves and roots of L. plants exposed to abiotic (methyl jasmonate, MJ, or/and copper, Cu) and biotic () factors were examined. The contribution of MJ as a signal molecule in the defense mechanism against abiotic and biotic stresses was studied. All plants were cultivated hydroponically and divided into three groups: not treated by abiotic factors (control), treated by MJ only (MJ) and by MJ and Cu (MJ + Cu) and in each group half of the plants were exposed to attack. The enzymatic activities of SOD, CAT, APX, and GPX in the leaves were higher in the insect-treated than non-insect-treated control plants, but lower in both MJ + Cu- or MJ- and insect-treated plants. In the roots, the enzyme activities were elevated in all insect-treated plants with the highest rise in MJ + Cu, in comparison with the MJ-treated plants. The results showed that MJ and MJ + Cu were efficient in reducing the activity of the antioxidative enzymes in the leaves under the insect influence by elevating enzyme activity in the roots.
