Transgenerational transmission of information about stress exposure is manifested as an increase in the somatic homologous recombination frequency in plants. Our aim was to investigate whether information about changes of antioxidative enzyme activities and protein HSP70 induction are also transmitted in response to stress caused by UV-C irradiation. These stress indicators were investigated in...

The changes in the components of the ascorbateglutathione system during the storage of potato {Solanum tuberosum L. cv. Spunta) tubers for 40 weeks at both 3 C and 9 C were studied in relation to lipid peroxidation. The level of malondialdehyde was found to be higher at 3 C than at 9 C throughout storage. Thus, lipid peroxidation, which is the main cause of membrane deterioration, was accelerat...

BACKGROUND Red-skin root disease has seriously decreased the quality and production of Panax ginseng (ginseng). METHODS To explore the disease's origin, comparative analysis was performed in different parts of the plant, particularly the epidermis, cortex, and/or fibrous roots of 5-yr-old healthy and diseased red-skin ginseng. The inorganic element composition, phenolic compound concentration...

introduction plant responses to environmental stress have a central role in agricultural production. responses results from events occurring at all levels of the organization, from biochemical reactions in cells to whole plant physiology. many plants are injured when exposed to low non-freezing temperatures. however, data on the effects of night temperatures are scarce. on the other hand, nitri...

The increase of environmental pollutants especially heavy metals derives from human industrial communities. Zinc is one of the natural elements that exist in biotic environment, plants body, and animals in different forms. Zinc has toxic and lethal effects in high concentrations on plants. Also some plants are introduced as accumulators of this element. Therefore, an investigation was carried o...
