to develop an optimal bioprocess for benzophenanthridin alkaloids production, various metabolite engineering are studied to increase yields, in which one of them is elicitation. elicitors are biotic or abiotic molecules that have effectively stimulated the production of plant secondary metabolites in cell and organ cultures. since this plant serves as the only commercial source of morphine and ...

zinc and iron nano-oxides (100 ppb) were promoted the hypericin and hyperforin production in hypericum perforatum cell suspension culture. high performance liquid chromatography method was used for detectection and identification of hypericin and hyperforin in h. perfuratum cell suspension cultures elicited with different concentrations of zinc and iron nano-oxide (0, 50, 100 and 150 ppb) after...

In the present study, we first attempted to achieve an efficient procedure for optimizing callogenesis from apical meristem and leaf explants of Salvia tebesana on MS media containing different concentrations BAP alone in combination with 2,4-D. Then, inducing effect nano-TiO2 (10, 60, 120 mg L−1) methyl jasmonate (50, 100, 200 µM), as abiotic elicitors were studied enhancement phenolic compoun...

Effects of different concentrations [0, 1, 5, 10, 20 and 40 mgL-1] of Fe3O4 and CuO nano-particles (nFe3O4 and nCuO) were investigated on sulforaphane (SFN) production level in 7-day-old seedlings of Lepidium draba at different time intervals (8 and 16 hrs). According to the results, the influence of the particles on SFN contentdepends on nano-particle (NP) concentrations, time of treatment as ...

In recent years, metabolism researches using nanomaterials have been focusing on human and animal cells, and therefore very limited data are available about influence of nanomaterials on biosynthesis of secondary metabolites in plant cells. Plants produce different types of secondary metabolites including terpenoids, phenolics, tannins, and alkaloids, which are known to act as vital mediators f...

S. rebaudiana produces steviol glycosides including stevioside and rebaudioside A that are valuable as low calorie sweeteners. The objective of this study was to investigate the effects of salicylic acid elicitation and sampling times on the improvment of stevioside and rebaudioside A production and KA13H, UGT74G1 and UGT76G1 genes expression. The results showed that the addition of different c...

in this study, it was intended to investigate the persian native speakers’ perception of gerunds by three different elicitation techniques i.e., written, audio, and pictorial through translation. eighty intermediate learners of english were asked to select persian translation of the gerund formsin these elicitation techniques. they were asked to choose one option from a pair of written first la...
