Acclimatization of tissue-cultured plants
A substantial number of micropropagated plants do not survive transfer from in vitro conditions to greenhouse or field environment. The greenhouse and field have substantially lower relative humidity, higher light level and septic environment that are stressful to micropropagated plants compared to in vitro conditions. The benefit of any micropropagation system can, however, only be fully reali...
متن کاملScreening seven Iranian medicinal plants for protective effects against β-Amyloid-induced cytotoxicity in cultured cerebellar granule neurons
Background and objectives: Alzheimer's disease (AD) as a neurodegenerative disorder is the most common form of dementia in the elderly. According to the amyloid hypothesis, accumulation of amyloid beta (Aβ) plaques, which are mostly constituted of Aβ peptide aggregates, triggers pathological cascades that lead to neuronal cell death. Thus, modulation of Aβ toxicity is the hopef...
متن کاملEnhanced rosmarinic acid production in cultured plants of two species of Mentha.
In the present investigation an attempt has been made to enhance rosmarinic acid level in plants, grown in vitro, of 2 species of Mentha in presence of 2 precursors in the nutrient media during culture. For in vitro culture establishment and shoot bud multiplication, MS basal media were used supplemented with different concentrations and combinations of different growth regulator like NAA (alph...

متن کاملComparative Investigations on the Metabolism of the Herbicide 2-(2,4-Dichlorophenoxy)-propionic Acid in Plants and Cultured Cells of Tomato*
The metabolism of [ l l4C]2-(2,4-dichlorophenoxy)-propionic acid was studied in excised plants and cell suspension cultures of tomato. It was rapidly taken up and metabolized by both the plants and the cultured cells. The m etabolites, isolated by extraction with aqueous acetone, separated and purified by TLC and HPLC, were identified by chemical and spectrometric methods. Conju gates with car...
