In present report effects of explants type, basal media and plant growth regulators (PGRs) were tested for induction of indirect somatic embryogenesis in medicinally important plant Silybum marianum L. Leaf, petiole and root explants were exploited in vitro on B5 (Gamborg), SH (Schenk and Hildebrandt) and MS (Murashige and Skoog) media for induction of(More)
The genus Digitalis L. is one of the most pharmacologically important plant genera because many Digitalis species produce cardenolides, which are commonly used for cardiac insufficiencies. In this study, different pretreatments were employed to increase germination of Digitalis cariensis seeds, which germinate poorly because of extensive dormancy. Seed(More)
Cardiac glycosides are plant natural compounds used to treat cardiac insufficiency in humans. Recent findings suggest a further medical use in oncology and virology. Since species of the genus Digitalis are the major source of these compounds, in vitro culture techniques can be useful tools for the propagation and selection of elite genotypes. Digitalis(More)
Digitalis cardenolides can regulate heart rhythms and are effective agents in cancer chemotherapy, in particular, for treating prostate and breast cancer. In this study, an optimized and efficient plant tissue culture protocol was established using callus cultures of Digitalis lamarckii Ivanina, commonly known as dwarf foxglove. Lamina explants developed(More)
Silybum marianum L. is a medicinal plant used in the treatment for jaundice and liver diseases. In this study, an adventitious root culture was developed for the production of health promoting phytochemicals. Adventitious roots were induced from nodal explants on solid Murashige and Skoog medium supplemented with 1.0 mg l−1 of α-Naphthalene acetic acid.(More)
This study aims to address the effects of different concentrations (0, 0.1, 1.0, 10, 100 or 1000 mg L-1) of engineered zinc oxide (ZnO) nanoparticles (34 nm in size) on growth parameters, steviol glycosides (rebaudioside A and stevioside) production and antioxidant activities in the tissue culture grown shoots of Stevia rebaudiana Bertoni. The highest(More)
Hydrogen peroxide (H2O2) functions as an abiotic stress elicitor for plants. In this study, the effect of oxidative stress caused by H2O2 on steviol glycosides (SGs) production and antioxidant activities of an in vitro grown antidiabetic plant, Stevia rebaudiana, has been investigated. Direct shoot organogenesis was performed, and after 4 weeks of culture,(More)
Stevia is a natural, zero-calorie, intensively sweet extracted from the leaves of Stevia rebaudiana. Its sweet taste derives from a group of compounds known as steviol glycosides. In this study, an efficient micropropagation protocol for S. rebaudiana was developed for possible commercial implementation using Murashige and Skoog (MS) basal medium without(More)
Copper oxide (CuO) nanoparticles (NPs) synthesized through co-precipitation method were employed in MS media during in vitro culture of Stevia rebaudiana. Physiological characteristics, production of steviol glycosides, and antioxidative parameters were investigated in regenerated plants. CuO NPs had crystalline monoclinic cubic cuprous oxides with average(More)
Cardenolides isolated from genus Digitalis are natural compounds used in treating cardiac insufficiencies. Recent investigations have also suggested the use of cardenolides in oncology. Due to the medicinal importance of the genus Digitalis, in vitro regeneration techniques would be useful for propagating the best genotypes selected from natural sources. To(More)
