Ozone-elicited secondary metabolites in shoot cultures of Melissa officinalis L.

Abstract: The effects of ozone treatment (200 ppb, 3 h) on the accumulation of main secondary metabolites have been investigated in Melissa officinalis (lemon balm) aseptic shoot cultures in order to evaluate the biotechnological application of this gas for improving the yield of secondary metabolites of medicinal plants. During the treatment, we found (i) an activation of enzymes involved in phenolic metabolism [as confirmed by the increase of shikimate dehydrogenase, phenylalanine ammonia-lyase and cinnamyl alcohol de… Show more

“…Spectrofluorimetric determinations were performed with a fluorescence/absorbance microplate reader (Victor3 1420 Multilabel Counter Perkin Elmer, Waltham, MA, United States) at 530 and 590 nm (excitation and emission resorufin fluorescence, respectively). O2 concentration was measured according to Tonelli et al (2015), after extraction with a Tris-HCl buffer (50 mM, pH 7.5), with a spectrophotometer (6505 UV-Vis, Jenway, United Kingdom) at 470 nm, and using a buffer solution as a blank.…”

“…Because anthocyanins occur so commonly across disparate vegetative organs, there has been concerted research effort to understand their functional significance, particularly in plants that experience abiotic stressors (Chalker-Scott 1999;Hoch et al, 2001;Steyn et al, 2002;Close and Beadle 2003;Gould, 2004;Manetas, 2006;Gould et al, 2009;Archetti, 2009a;Hughes, 2011;Tonelli et al, 2015). Nonetheless, after well over a century of research and despite a comprehensive knowledge on the regulation of anthocyanin biosynthesis (Winkel, 2006), their functional roles in plant-environment interactions remain highly contested (for a review see Gould et al, 2009).…”

“…The quality and continuous production of essential oils is very important to supply market demands and the industry requirements, even under adverse environmental conditions such as drought, salinity, and extreme temperatures (Silva, 2002;Çoban and Baydar, 2016). These adverse conditions strongly affect the biosynthesis and production of secondary metabolites in medicinal and aromatic plants, causing increase or decrease in the essential oils' yield and changes in their composition (Lopes and Gobbo-Neto, 2007;Kim et al, 2010;Tonelli et al, 2014). Abiotic stresses such as drought and salinity cause negative effects on growth and development of medicinal plants (Khorasaninejad et al, 2010).…”
