Scrophularia kakudensis is an important medicinal plant with pharmaceutically valuable secondary metabolites. To develop a sustainable source of naturaceuticals with vital therapeutic importance, a cell suspension culture was established in S. kakudensis for the first time. Friable calli were induced from the leaf explants cultured on a Murashige and Skoog (MS) medium containing 3.0 mg·L(-1) 6-...

Antioxidant activity is an important feature for evaluating fruit quality and tolerance to biotic or abiotic stresses. Moreover, antioxidant involved in chilling injury (CI) response postharvest fruit. Chemical elicitors can induce systemic acquired resistance against pathogens, which could partially replace synthetic fungicides. Recently, researchers have found that preharvest sprays with chem...

Pea (Pisum sativum L. cv Alcan) endocarp tissue challenged with an incompatible fungal pathogen, Fusarium solani f. sp. phaseoli or fungal elicitors results in the induction of pathogenesis-related (PR) genes and the accumulation of pisatin, a phytoalexin. Essentially the same response occurs in pea tissue exposed to DNA-specific agents that crosslink or intercalate DNA. In this study, the effe...

in biotechnology has been concentrated to review alternative routes for the production of natural compounds. plant cell culture systems are viable alternatives for the production of secondary metabolites that are of commercial importance in food and pharmaceutical industries. however, relatively very few cultures synthesize these compounds over extended periods in amounts comparable to those fo...

BACKGROUND Elicitation, which is a way of inducing plant secondary metabolism, may be an effective method for improving the quality of plant food. The aim of this study was to determine how the application of jasmonic acid (as an abiotic elicitor) and yeast extract (as a biotic elicitor) influences the production of some bioactive compounds in marjoram and the antioxidant activity of this herb....

The high sensitivity and frequency selectivity of the mammalian cochlea is due to amplification produced by outer hair cells (OHCs) and controlled by medial olivocochlear (MOC) efferents. Data from animals led to the view that MOC fibers provide frequency-specific inhibitory feedback; however, these studies did not measure intact MOC reflexes. To test whether MOC inhibition is primarily at the ...

Plants can defend themselves against fungal infection by natural means induced by biotic and abiotic elicitors. Osthol is a natural compound extracted from dried fruits of Cnidii Monnieri Fructus. In this study, it has been shown to not only be a fungicide with acceptable curative properties (control efficacy of 68.72), but it also showed a significant prophylactic effect (with control efficacy...
