“…However, taxol production has been discovered also in a wide variety of fungal species like the endophytic fungi Pestalotiopsis microspora and Stemphylium sedicola which have been isolated from plant species of the genus Taxus and Taxodium . Likewise, the compounds azadirachtin A and B, which are widely used as natural insecticides and traditionally isolated from neem tree, Azadirachta indica , are also produced by the endophytic fungus Eupenicillium parvum isolated from neem tree [ [23] , [24] , [25] , [26] , [27] ].…”

Highlights MeJA and SA induced a differential metabolic production in elicited cell suspensions. Production of metabolites was dependent on the type and the concentration of elicitor. Elicitation with SA produced the greatest changes in the metabolic profile. 5-hidroximetilfurfural, (Z)-9-octadecenamide and phenol were induced by elicitation.

“…From that moment, an exponential increase of manuscripts focused on SA (acting alone or in concert with other plant hormones) as a plant growth regulator, signaling molecule, as well as plant elicitor protecting plants from biotic and abiotic stress, was observed [22,23,[26][27][28][29][30][31].…”

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.

“…In agreement with published literature reporting that various elicitors can successfully increase the production of GLSs and/or PHs in some brassica plants, we observed a significant increase in the accumulation of these compounds in the leaves of Chinese kale plants after liquiritin application as an exogenous elicitor. The identification and quantification of the individual GLSs and PHs were based on a UFLC‐ESI‐MS/MS analysis.…”

BACKGROUND: Brassica oleracea var. alboglabra (Chinese kale) is an important vegetable grown in southernChina. This study was aimed at searching for environmentally friendly and affordable approaches to increase the production of medicinally relevant glucosinolates and phenolic compounds in Chinese kale plants. For this purpose, the foliar application of liquiritin at 0 (control), 250, 500 and 750 ppm was tested starting from the four-leaf stage and repeated every two weeks until plants were two months old. RESULTS: Foliar application of liquiritin in Chinese kale plants significantly increased glucosinolates and total phenolic content, in a dose-dependent manner. Compared with control plants, 2.3-and 1.9-fold increases in yields of glucosinolates and total phenolic content, respectively, were corroborated in Chinese kale plants treated with 750 ppm of liquiritin. Along with rises in the content of eight different glucosinolates, liquiritin elicitation effectively increased the concentration of glycosilated and acylated flavonoids and hydroxycinnamic acids. The expression of genes involved in glucosinolate and phenolic biosynthesis was significantly higher in liquiritin-treated plants as compared to controls.CONCLUSIONS: Liquiritin elicitation is a feasible and environmentally friendly practice for increasing the production of medicinally important glucosinolates and phenolic compounds in Chinese kale, which may improve this plant's value as a nutraceutical food. This study also contributes to understanding the molecular mechanisms underlying liquiritin elicitation. This is the first report documenting the use of liquiritin for an elicitation purpose in plants.Liquiritin elicitation increases medicinal properties of Chinese kale www.soci.org Identification and quantification of individual GLSs and PHs Alkaline hydrolysisTo eliminate acid moieties, which generate mass spectra coincident with those of rhamnosyl and hexosyl residues and may lead to miss-assignments during mass spectroscopic analysis, alkaline J Sci Food Agric 2020; 100: 1616-1624
