“…Our findings could also be attributed to the fact that MJ affects many metabolic processes and therefore objective conclusions are difficult to formulate. One of such processes involves the accumulation of large amounts of 2-phenylethylamine [20,29]. According to Seltman et al [30], natural senescence differs from stressinduced senescence.…”

The effect of methyl jasmonate (MJ) vapors on the composition and peroxidation of major fatty acids in the organs of common buckwheat seedlings was investigated. The composition of fatty acids in the hypocotyl and cotyledons of seedlings changed significantly under exposure to MJ vapors in closed jars. Four-day exposure to MJ led to a significant reduction in the concentrations of stearic, linoleic, and linolenic acids in the hypocotyl, whereas oleic acid levels increased approximately 3.5-fold. A decrease in stearic acid levels and an increase in the content of linolenic acid were noted in cotyledons, whereas oleic acid levels decreased in roots. Seven-day exposure to MJ vapor caused a further reduction in stearic acid content and an increase in oleic acid and linoleic acid levels in the hypocotyl. At the same time, the linoleic acid content of roots and linolenic acid levels in cotyledons were doubled, but a 5-fold reduction in linolenic acid concentrations was observed in roots. Methyl jasmonate intensified fatty acid peroxidation in cotyledons after 4 and 7 days and in roots after 4 days of exposure. Peroxidation was inhibited in the hypocotyl and roots after 7 days. The noted changes in the composition and peroxidation of fatty acids are probably indicative of senescence in buckwheat seedlings under the influence of MJ. Senescence seems to proceed faster in cotyledons than in other organs of buckwheat seedlings.

“…The potency of MJ to trigger an accumulation of diverse secondary metabolites in plants has been widely reported (Pauwels et al, 2008;Horbowicz et al, 2011;Ruiz-May et al, 2011;Concha et al, 2013). The majority of these studies were related to the metabolism of phenylpropanoids, indole alkaloids and terpenoids (Pauwels et al, 2008;Chen et al, 2013).…”

Transcriptomic analyses performed by Chen et al (2013) demonstrated that MJ evoked rapid and circumstantial alternations in the expression pattern of genes involved in the biogenesis of indole alkaloids, terpenoids and putative phenylpropanoids pathways in the hairy roots of Isatis indigotica L. plants.…”

“…The presence of 2-phenylethylamine (PEA) has been confirmed in several species of plants (Smith, 1977;Horbowicz et al, 2011;Le Thi et al, 2014). Smith (1977) suggested the role of PEA in constituting the plant resistance towards a wide range of insect pests.…”

“…Methyl jas monate stimulates a high-level accumulation of 2-phenylethylamine (PEA) in de-etiolated seedlings of common buckwheat (Fagopyrum esculentum Moench) (Horbowicz et al, 2011). This transformation is catalyzed by amino acid decarboxylase (AADC), wherein L-phenylalanine is used as a substrate.…”

The objective of the study was to assess the influence of methyl jasmonate (MJ) vapors on accumulation of 2-phenylethylamine (PEA), phenylacetic acid (PAA) and 2-phenylethanol (PE) in leaves and roots of maize (Zea mays L. subsp. mays, saccharata group, cv. Złota Karłowa) seedlings. Furthermore, we analyzed the expression patterns of eight genes (ADH1, ADH2, AO2, CAO, PDC1, PDC2, PTA and LOX, encoding alcohol dehydrogenase 1 and 2, primary amine oxidase, aldehyde oxidase 2, phenylalanine decarboxylase 1 and 2, phenylalanine (histidine) transaminase and lipoxygenase, respectively) involved in biosynthesis and turnover of PEA in maize tissues. In addition, the effect of MJ application on fresh biomass and growth of the tested seedlings was recorded. Oneday MJ exposure increased the fresh weight of aerial parts and roots of Z. mays seedlings, whereas the opposite tendency occurred after 4-day of MJ treatment. One-day application of MJ resulted in an increase in the length of roots and its fluctuations in the aerial parts of maize plants, but extended exposure declined the growth of both parts of the seedlings. Methyl jasmonate elicitation caused various changes in the contents of PEA, PAA and PE in the maize seedlings. MJ treatments led to high upregulation of most genes, with the exception of three genes (i.e., ADH1, ADH2 and AO2) whose expression was downregulated after a 4-day exposure.

Phenolic composition of Tempranillo Blanco (Vitis vinifera L.) grapes and wines after biostimulation via a foliar seaweed application

BACKGROUND Seaweeds are defined as novel elicitors in many crops, allowing the synthesis of secondary metabolites to be triggered in different plant tissues. Currently, the phenolic composition of Tempranillo Blanco grapes and wines is unreported. The present study aimed to investigate the effects of an Ascophyllum nodosum seaweed extract applied to Tempranillo Blanco grapevines, at low (Ld) and high (Hd) dosages, on grape and wine phenolic compounds during two consecutive seasons (2017–2018). RESULTS The results obtained showed that catechin was the most abundant phenolic compound in Tempranillo Blanco grapes and wines. Season affected the weight of 100 berries and some enological parameters. Catechin and flavonols concentrations in grapes were increased after Hd application to grapevines, independently of season. The concentration of hydroxycinnamic and hydroxybenzoic acids in wines was affected by vintage, probably as a result of oxidation reactions, as well as pinking phenomena, whereas the stilbenes content in wines was conditioned by the affect of cryptogamic diseases in grapes. CONCLUSION Seaweeds might act as an elicitor of several phenolic compounds in grapes, enhancing the content of some phenolic compounds in wines. © 2019 Society of Chemical Industry
