Flavonoids are small molecular secondary metabolites synthesized by plants with various biological activities. Due to their physical and biochemical properties, they are capable of participating in plants' interactions with other organisms (microorganisms, animals and other plants) and their reactions to environmental stresses. The majority of their(More)
Fructose 2,6-bisphosphate (fru-2,6-P2) is a signalling metabolite that regulates photosynthetic carbon partitioning in plants. The content of fru-2,6-P2 in Arabidopsis leaves varied in response to photosynthetic activity with an abrupt decrease at the start of the photoperiod, gradual increase through the day, and modest decrease at the start of the dark(More)
The principal goal of this paper was to generate flax (Linum usitatissimum L.) plants with increased antioxidant properties. To accomplish this a vector containing a multigene construct was prepared, and transgenic plants overexpressing essential flavonoid biosynthesis pathway enzymes were generated and analyzed. The simultaneous expression of genes(More)
The aim of this study was to engineer a flax with increased resistance to pathogens. The approach was based on the recent analysis of the Solanum sogarandinum -derived glycosyltransferase (UGT) protein, designated SsGT1 (previously called 5UGT). On the basis of enzyme studies, the recombinant SsGT1 is a 7-O-glycosyltransferase, the natural substrates of(More)
BACKGROUND Flaxseed oil is characterized by high content of essential polyunsaturated fatty acids (PUFA) promoted as a human dietary supplement protecting against atherosclerosis. The disadvantage of the high PUFA content in flax oil is high susceptibility to oxidation, which can result in carcinogenic compound formation. Linola flax cultivar is(More)
The great diversity of wounds and the broad range of available dressings complicate the selection of proper chronic wound treatment. Choosing the right treatment is the essential step in the healing process. In this review, we focus on chronic nonhealing ulcers, which are a critical problem in clinical practice, and current knowledge about persistent wound(More)
The sensitivity of the available methods of apoptosis detection in lymphocyte cultures was tested. Cells were preincubated with genotoxic agents: hydrogen peroxide (0.2 mM; 20 min.) and benzo[a]pyrene (40 microM; 90min.), and then cultured for 36h in the presence of a lectin (PHA-M; 1% v/v) and one of the following potentially antimutagenic agents:(More)
Flax (Linum usitatissimum L.) is a raw material used for important industrial products. Linen has very high quality textile properties, such as its strength, water absorption, comfort and feel. However, it occupies less than 1% of the total textile market. The major reason for this is the long and difficult retting process by which linen fibres are(More)
A new flax dressing product was developed based on three components (fibers, oil emulsion, and seedcake extract) from genetically engineered flax plants that were obtained by plant transformation using three genes controlling the synthesis of antioxidative compounds from the phenylpropanoid pathway. Simultaneous flax explant transformation with three genes(More)
Fusarium is the most common flax pathogen causing serious plant diseases and in most cases leading to plant death. To protect itself, the plant activates a number of genes and metabolic pathways, both to counteract the effects of the pathogen, and to eliminate the threat. The identification of the plant genes which respond to infection is the approach, that(More)
