“…Many studies involving various species have been performed to elucidate the role of JA in fruit ripening (Saniewski et al, 1987;Fan et al, 1997;Kondo et al, 2009;Concha et al, 2013;Khan and Singh, 2015). For example, Kondo et al (2000) reported that endogenous JA levels increase in apple fruit during maturation.…”

“…MeJA is not only a vital regulator in plant defense responses against biotic and abiotic stresses [22][23][24], but also plays a role in plant physiological processes, such as fruit ripening [25], stomatal closure [26], etc. Moreover, research has indicated that exogenous application of MeJA to plant cell cultures or to the intact plant can stimulate the accumulation of a wide range of plant secondary metabolites [27], including terpenoids [28], flavonoids [29], and alkaloids [30] and up-regulate expression of the genes involved in their biosynthesis [31][32][33].…”

Methyl jasmonate-induced accumulation of metabolites and transcriptional responses involved in triterpene biosynthesis in Siraitia grosvenorii fruit at different growing stages

The cucurbitane-type triterpenoid glycosides, mogrosides, are the main active components of Siraitia grosvenorii fruit. Squalene and cucurbitadienol are among the intermediates of the biosynthetic pathway for the formation of cucurbitanetype triterpenoid backbones of mogrosides. It is recognized that the exogenous application of methyl jasmonate (MeJA) increases the accumulation of secondary metabolites in various plant species. Here, the effect of MeJA (50, 200, and 500 μM) on the accumulation of squalene and cucurbitadienol in the fruits of S. grosvenorii at 10, 20, and 30 days after flowering (DAF) was tested for the first time. Since mogroside II E is the main cucurbitane-type triterpenoid present at this time, its concentration was also determined. The results show that MeJA can indeed promote squalene and cucurbitadienol accumulation, the application of 500 μM MeJA at 30 DAF being optimal. The concentration of squalene and cucurbitadienol increased up to 0.43 and 4.71 μg/g dry weight (DW), respectively, both of which were 1.2-fold greater than that of the control. The content of mogroside II E increased by 15% over the untreated group. We subsequently analyzed the expression of key genes involved in the mogroside biosynthetic pathway, including the 3-hydroxy-3-methylglutaryl-coenzyme A reductase gene (SgHMGR), squalene synthetase gene (SgSQS), cucurbitadienol synthase gene (SgCS), and cytochrome P450 (SgCYP450) with quantitative real-time PCR. The results showed that transcriptional levels of these genes were upregulated following the treatment described above. Additionally, their responses in the presence of MeJA was related to the concentration and timing of MeJA treatment.

“…Kim et al (2003) identified the biphasic pattern of upregulation of the LOX gene expression (two peaks of LOX transcript accumulation at 6 and 24 h, respectively) in the maize seedlings exposed to MJ treatment. Similarly, Concha et al (2013) also elucidated considerable increments in the levels of LOX gene expression in fruits of Fragaria chiloensis L. (Mill.)…”

“…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).…”

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.
