The effects of various light intensities and spectral compositions on glutathione amino acid metabolism were compared in wheat. Increase intensity (low—normal—high) was accompanied by a simultaneous increase the shoot fresh weight, photosynthetic activity content. These parameters also affected modification ratios blue, red far-red components (referred to as pink lights) normal white light. content decreased 50% percentage disulfide (characterising redox state tissues) total pool doubled...
To satisfy future demands, the increase of wheat (Triticum aestivum L.) yield is inevitable. Simultaneously, maintaining high crop productivity and efficient use nutrients, especially nitrogen efficiency (NUE), are essential for sustainable agriculture. NUE its components inherently complex highly influenced by environmental factors, management practices genotypic variation. Therefore, a better understanding their genetic basis regulation fundamental. investigate NUE-related traits...
Salinity-induced osmotic, ionic and oxidative stress responses were investigated on Asakaze/Manas wheat/barley addition lines 7H, 7HL 7HS, together with their barley (salt-tolerant) wheat (relatively salt-sensitive) parents. Growth, photosynthetic activity, chlorophyll degradation, proline, glycine betaine accumulation, sugar metabolism, Na+ K+ uptake transport processes the role of polyamines antioxidants studied in young plants grown hydroponic culture or without salt treatment. Changes...
Abstract It is shown that plasma‐activated water (PAW) improves tolerance against combined low temperature and hypoxia stresses during germination. Due to PAW's effect on the antioxidant system, PAW pretreatment mitigates reducing plant growth of hydroponically applied NaCl. reduces salt‐stress‐induced decrease cysteine γ‐glutamylcysteine content plant's recovery after NaCl stress. also modifies NaCl‐induced changes in carotenoid content, especially, β‐carotenes xanthophylls. These...
It is established that, besides the cold, incident light also has a crucial role in cold acclimation process. To elucidate interaction between these two external hardening factors, barley plantlets were grown under different conditions with low, normal, and high intensities at 5 15 °C. The expression of HvCBF14 gene well-characterized members C-repeat binding factor (CBF)-regulon HvCOR14b HvDHN5 studied. In general, level studied genes was several fold higher °C than that independently...
Polyamines are multifaceted compounds which play a role in regulating plant growth and stress tolerance interactions with hormones. The aim of the present study was to reveal how exogenous polyamines influence synthesis salicylic acid, special emphasis on effect acid deficiency polyamine metabolism polyamine-induced changes other hormone contents. Our hypothesis that individual induced different wild type acid-deficient Arabidopsis mutants, turn influenced To our knowledge, such side-by-side...
Cold acclimation, the necessary prerequisite for promotion of freezing tolerance, is affected by both low temperature and enhanced far-red/red light (FR/R) ratio. The impact FR supplementation to white light, created artificial LED sources, on hormone levels, metabolism, expression key metabolism-related genes was determined in winter barley at moderate (15 °C) (5 temperature. FR-enhanced tolerance 15 °C associated with abscisic acid (ABA) accompanied a increase indole-3-acetic (IAA)...
CBF (C-repeat binding factor) transcription factors show high expression levels in response to cold; moreover, they play a key regulatory role cold acclimation processes. Recently, however, more and information has led the conclusion that, apart from cold, light—including its spectra—also crucial regulating expression. Earlier, studies established that patterns of some these genes follow circadian rhythms. To understand this complex process, we studied signal transducing pathways, including...
Catharanthus roseus is a very rich source of medically important alkaloids. However, since their concentrations are extremely low in plant tissues, many efforts have been made to increase the alkaloids level - among them application various elicitors. Since synthetized by complex pathway, detailed knowledge molecular background system essential. The current job aimed study effect two elicitor, methyl jasmonate (MeJa) and UV-B irradiation, also simultaneous effect, on expression patterns key...
Non‐infected and infected cereal crops, respectively, are treated in the afterglow of Ar/N 2 ‐O surface‐wave microwave discharges at 2–8 mbar pressure. It is shown, that germination vigour non‐infected seeds not significantly effected, when barley max 120 s maize 240 4 mbar. On other hand, can be disinfected from inhibitors Fusarium graminearum verticillioides . The most efficient treatment, which also increases above 80%, for 3 min Ar‐20%O mbar, while + N ‐2%O 8 high NO content mixtures...
The wheat and barley CBF14 genes have been newly defined as key components of the light quality-dependent regulation freezing tolerance by integration phytochrome-mediated temperature signals. To further investigate wavelength dependence light-induced expression in cereals, we carried out a detailed study using monochromatic treatments at an inductive non-inductive temperature. Transcript levels gene winter Cheyenne, einkorn G3116 Nure genotypes were monitored. We demonstrated that (1) is...
Spectral quality, intensity and period of light modify many regulatory stress signaling pathways in plants. Both nitrate sulfate assimilations must be synchronized with photosynthesis, which ensures energy reductants for these pathways. However, photosynthesis is also a source reactive oxygen species, whose levels are controlled by glutathione other antioxidants. In this study, we investigated the effect supplemental far-red (735 nm) blue (450 lights on diurnal expression genes related to...
Phosphatidylinositol transfer protein (PITP) and phosphatidylinositol 4-kinase (PI4K) are very upstream regulatory elements of the phospholipid signaling pathway in signal transduction network. Unlike animal systems, their role stress is poorly understood plants. To study this area, PITP- PI4K-overexpressing transgenic barley lines were developed. Morphological developmental abnormalities surveyed characterized. It was revealed that overexpression genes led to more phenotypic than other...
The assumed modulating effect of supplementary blue (B) and far-red (Fr) light on the Cd-induced changes various biochemical processes was clarified in Lemna minor L. While tolerance plants against Cd is mainly based its chelation by phytochelatins white (W) light, defence process also enhanced lower uptake B Fr light. Interestingly, reduced synthesis from glutathione (GSH) lights only associated with greater GSH levels This increased content could contribute to maintenance proper redox...
A mikorrhiza gombák oltóanyagként történő alkalmazásakor kedvező hatás jelentkezhet a növény környezeti stresszel (nehézfém, szárazság, só) szembeni ellenálló képességében, így használatuk jelentősen hozzájárulhat termésátlag ingadozásának csökkentéséhez és termésbiztonság növeléséhez. Munkánk célja volt, hogy különböző időpontban arbuszkuláris oltás fűszerpaprika növekedésére termésmennyiségére gyakorolt hatását megvizsgáljuk normál szárazság stresszt előidéző csökkentett vízmennyiséggel...
