Brassinosteroids Promote Growth and Secondary Metabolite Production in Lavandin (Lavandula intermediaEmeric ex Loisel.)

New Tricks for Old Guys: Recent Developments in the Chemistry, Biochemistry, Applications and Exploitation of Selected Species from the Lamiaceae Family

“…Foliar application of 1.5 mg/L of 24‐epibrassinolide (a brassinosteroid analogue) on an eight years old plant of Lavandula x intermedia var. Super increase the EO yields from 6.2 % to 8.7 % (v/w) and also the percentage of linalyl acetate from 27.3 % to 30.5 % . Negative impact on the quantity and quality of the O. majorana EO has been expressed by the application of hydroalcoholic extract of Zingiber officinale , while a considerable increment of EO quantity and thymol stabilization of percentage range within analyzed population of T. vulgaris was obtained by Pavela and coworkers, with the foliar application of mixed N, P, K and salicylic acid.…”

“…Super increase the EO yields from 6.2 % to 8.7 % (v/w) and also the percentage of linalyl acetate from 27.3 % to 30.5 %. [169] Negative impact on the quantity and quality of the O. majorana EO has been expressed by the application of hydroalcoholic extract of Zingiber officinale, [170] while a considerable increment of EO quantity and thymol stabilization of percentage range within analyzed population of T. vulgaris was obtained by Pavela and coworkers, [171] with the foliar application of mixed N, P, K and salicylic acid. Again, a recent study on T. vulgaris showed that treatment with abiotic elicitors [152] lead to differential up-regulation of genes involved in thymol/carvacrol biosynthesis with the probable consequent increment of the corresponding metabolites.…”

Increasing of Phenolic Compounds by Brassinosteroid Applications in Immobilized Cell Suspension Cultures of Vitis vinifera L. cv. Cinsault

“…Thus, it promotes the synthesis of phenolic compounds (Xi et al 2013;Li et al 2016). Asci et al (2019) reported that exogenous applied BR acts as a signaling molecule to increase phenolic biosynthesis and enhances metabolite accumulation by affecting enzymes and genes involved in biosynthesis. In previous studies, it was found that BR applications increased total phenol and antioxidant capacity compared to control treatment (Xi et al 2013;Ghorbani et al 2017).…”

“…24-eBL is the most effective and stable BR analog and has been found to high stimulatory effect in enzymatic activity and antioxidant systems in the majority of studies (Hayat et al 2010). Moreover, 24-eBL also promote the production of secondary metabolites in several plants (Çoban & Baydar 2017;Asci et al 2019) and the exogenous application of BRs has been determined to increase antioxidant capacity and phenolic content in grapes (Luan et al 2013;Xi et al 2013;Ghorbani et al 2017;Wang et al 2019;Babalık et al 2020). Although there are few studies conducted the impact of immobilization on the increased accumulation of secondary metabolites in several plants (Choi et al 1995;Gillet et al 2000;Dornenburg 2004) and grapevine (Iborra et al 1994;Guardiola et al 1996), there is no study to determine on the effect of brassinosteroid applications on phenolic contents of grapes in immobilized cultures.…”

Variation in phytochemical properties and expression of key genes involved in biosynthesis of hypericin using nano-capsulated and normal hormones in Hypericum perforatum L

“…Furthermore, the use of nano-hormones might affect the metabolites or other health bene t compounds in plants in an e cient way. There are several reports regards the effect of normal hormones on valuable metabolites of plants including salicylic acid for thymol (Mohammadi et al, 2019), 24-epibrassinolides for lavandin in Lavandula intermedia (Aras Asci et al, 2019), cycocel in sage and peppermint (Keltawi and Croteau, 1986). The use of plant hormones and other elicitors for increasing of hypericin, hyperforin have been reported in some literatures (Shakya et al, 2019;Cirak et al, 2020).…”
