Effects of methyl jasmonate and salicylic acid on the production of bilobalide and ginkgolides in cell cultures of Ginkgo biloba

The results from this study suggest that MJ and SA directly or indirectly increased the production of B, GA, and GB in cells, and stimulated the release of these metabolites into the culture medium.

Effects of methyl jasmonate and phloroglucinol on thebaine and sanguinarine production in cell suspension culture of Persian poppy (Papaver bracteatum Lindl.).

Investigation of the effects of different concentrations of methyl jasmonate and phloroglucinol on thebaine and sanguinarine productions in vitro indicated that the highest production rate has been achieved through a synergic effect of two elicitors after 48 h.

Effects of methyl jasmonate and salicylic acid on tanshinone production and biosynthetic gene expression in transgenic Salvia miltiorrhiza hairy roots

The two elicitor treatments suggested that tanshinone accumulation positively correlated to the expression of key genes such as SmGGPPS, SmCPS, and SmKSL, which paved the way for further metabolic engineering of tansinone biosynthesis.

Enhanced production of tropane alkaloids in transgenic Scopolia parviflora hairy root cultures over-expressing putrescine N-methyl transferase (PMT) and hyoscyamine-6β-hydroxylase (H6H)

The results suggest that PMT1, PMT2, and H6H genes may not only be involved in the metabolic regulation of alkaloid production but also that these genes may play a role in the root development.

The effects of elicitation on the expression of key enzyme genes and on production of tropane alkaloids in Anisodus acutangulus plant

The results revealed that TA production was induced by all the three treatments, however, its quantity varies with inducers used, and this is the first report on the relationship between TA production and genes expression profile induced by different elicitors in cultivated A. acutangulus plant.

Enhanced production of valtrate in hairy root cultures of Valeriana jatamansi Jones by methyl jasmonate, jasmonic acid and salicylic acid elicitors

Valtrate is a pharmacologically active epoxyiridoid ester found in the roots and rhizomes of Valeriana jatamansi Jones. The plant produces only small amounts of this metabolite naturally, and so

The isolation and expression analysis of cinnamate 4-hydroxylase and chalcone synthase genes of Scrophularia striata under different abiotic elicitors

The phenylpropanoid pathway serves as a rich source of metabolites in plants, and it is considered as a starting point for the production of many other important compounds such as the flavonoids,



Effects of abiotic inducers on sesquiterpene synthesis in hairy root and cell-suspension cultures ofhyoscyomus muticus

The effects of hydrogen peroxide (H2O2), salicylic acid (SA), ethanol (EtOH), and methyl jasmonate (MJ) on the lubimin and solavetivone production in hairy root and cell suspension cultures

Necessity of a Functional Octadecanoic Pathway for Indole Alkaloid Synthesis by Catharanthus roseus Cell Suspensions Cultured in an Auxin-Starved Medium

Data suggest that in response to auxin depletion, endogenous mJA could be produced and act by linking physiological events thus leading to alkaloid biosynthesis activation.

Involvement of the octadecanoid pathway and protein phosphorylation in fungal elicitor-induced expression of terpenoid indole alkaloid biosynthetic genes in catharanthus roseus

Results demonstrate that the jasmonate biosynthetic pathway is an integral part of the elicitor-triggered signal transduction pathway that results in the coordinate expression of the Tdc and Str genes and that protein kinases act both upstream and downstream of jAsmonates.

Effects of salicylic acid on growth and stomatal movements ofVicia faba L.: Evidence for salicylic acid metabolization

The results indicate that, under natural conditions, salicylic acid will not act as an allelopathic compound whose toxic properties severely affect the growth of Vicia faba.

Hyoscyamine 6 beta-hydroxylase, an enzyme involved in tropane alkaloid biosynthesis, is localized at the pericycle of the root.

Hyoscyamine 6 beta-hydroxylase (H6H; EC catalyzes the first reaction in the biosynthetic pathway from hyoscyamine to scopolamine in several solanaceous plants. Four monoclonal antibodies

Methyl jasmonate-induced rosmarinic acid biosynthesis in Lithospermum erythrorhizon cell suspension cultures

A dramatic increase in rosmarinic acid content in cultured cells of Lithospermum erythrorhizon was observed after their exposure to methyl jasmonate, and the response of the cultured cells to MJ-treatment was slower than that to YE-treatment.
