The best-characterized functional motifs of the potyviral Helper-Component protease (HC-Pro) responding for aphid transmission, RNA silencing suppression, movement, symptom development, and replication are gathered in this review. potential cellular protein targets plant virus proteases remain largely unknown despite their multifunctionality. HC-Pro catalytic domain, as a cysteine protease, autoproteolytically cleaves polyproteins sequence motif YXVG/G is not expected to act on host targets;...
Salt stress is one of the most damaging plant stressors, whereas hypoosmotic not considered to be a dangerous type in plants and has been less extensively studied. This study was performed compare metabolism cucumber grown soil with transferred distilled water 100 mM NaCl solution. Even though caused by did cause such significant changes relative content, Na+/K+ ratio Rubisco content as those salt stress, it accompanied more pronounced specific activities NADP-dependent enzymes. After 3...
Pythium oligandrum is a unique biological control agent. This soil oomycete not only acts as mycoparasite, but also interacts with plant roots and stimulates defense response via specific elicitors. In addition, P. can synthetize auxin precursors stimulate growth. We analyzed the secretomes biochemical properties of eleven isolates to find novel effective strain advantageous features for plants. Our results showed that even closely related significantly differ in content compounds secreted...
Many factors affect successful virus propagation and plant defence responses. Heat shock protein (Hsp) expression after heat plays an ambiguous role in viral infection. On the one hand, Hsp70 participates response; on other could interact with proteins facilitate propagation. Here, we studied metabolic adaptations of Nicotiana tabacum L. subjected to (42 °C, 2 h) before or inoculating plants Potato Y (potyvirus). RT-qPCR ELISA were used for potyvirus quantification. Hsp90 isoforms analysed...
Heat shock and almost all types of stresses associated with oxidative stress are accompanied by heat protein (HSP) expression. HSPs involved in refolding denatured proteins directing unrepairable for degradation. Thus, under conditions, help to restore cellular balance. However, virus-infected plants, HSP70 can have both positive negative effects because viruses usually recruit HSP70. promote the replication translation viral genome, formation complexes, propagation particles from cell...
Pseudomonas aeruginosa is one of the most antibiotic multi-resistant bacteria, causing chronic pulmonary disease and leading to respiratory failure even mortality. Thus, there has been an ever-increasing search for novel preferably natural antimicrobial compounds. Agrimonia eupatoria L. Origanum vulgare shoots are commonly used as teas or alcoholic tinctures their human health-promoting antibacterial properties. Here, we explored effects all plant parts, i.e., leaf, flower, stem, root...
Abstract In contrast to inorganic nitrogen (N) assimilation, the role of organic N forms, such as proteins and peptides, sources their impact on plant metabolism remains unclear. Simultaneously, biostimulants are used priming agents improve defense response. Here, we analysed metabolic response tobacco plants grown in vitro with casein hydrolysate or protein. As sole source N, enabled growth, while protein was only a limited extent. Free amino acids were detected roots but not no N....
Several 1,2,4-triazoles are widely used as systemic fungicides in agriculture because they inhibit fungal 14ɑ-demethylase. However, can also act on many non-target plant enzymes, thereby affecting phytohormonal balance, free amino acid content, and adaptation to stress. In this study, tomato plants (Solanum lycopersicum L. var. 'Cherrola') were exposed penconazole, tebuconazole, or their combination, either by foliar spraying soil drenching, every week, an ecotoxicological model. All...
The balance of water between the cell and its environment is crucial to all organisms, but especially for root plant cells that are exposed extrinsic condition directly.High salt concentration in soil leads loose from (hyper-osmotic stress).Sufficient supply with causes turgid (i.e.increases volume, membrane experiences turgor pressure interior against resistance wall), which healthy state most plants.However, upon repeated flooding (e.g. a tropical rain-forest climate), plants may...
Pythium oligandrum, strain M1, is a soil oomycete successfully used as biological control agent (BCA), protecting plants against fungal, yeast, and pathogens through mycoparasitism elicitor-dependent plant priming. The not yet described strains, X42 00X48, have shown potential BCAs given the high activity of their secreted proteases, endoglycosidases, tryptamine. Here, Solanum lycopersicum L. cv. Micro-Tom seeds were coated with seedlings exposed to fungal pathogens, either Alternaria...
The pyruvate, orthophosphate dikinase (PPDK, EC 2.7.9.1), crucial plant enzyme in the process of concentrating CO2 for Calvin cycle, catalyzes phosphoenolpyruvate-regeneration phase C4 photosynthetic pathway. However plants possess also nonphotosynthetic isoform PPDK, which functions are less understood, probably due to its low abundance. In all plants, PPDK is located both cytoplasmic and plastidic compartments. reversible ATP- Pi- dependent formation phosphoenolpyruvate from pyruvate.
Triazole fungicides can threaten plants as abiotic stressors but also positively affect plant defense by inducing priming. Thus, yield is both protected and endangered triazoles that may influence several metabolic pathways during maturation processes, such the biosynthesis of saccharides or secondary metabolites. Here, Solanum lycopersicum L. were exposed to foliar soil applications penconazole, tebuconazole, their combination, resulting effect on tomato fruits was followed. The exposure...
Phenylpropanoids (or phenolic compounds) are a large class of plant secondary metabolites usually consisting six-carbon aromatic phenyl group and three-carbon propane side chain.Flavonoids, monolignols (precursors lignin), acids three most common groups, which can be found almost in all plants [1].These compounds have important functions as antibiotics, natural pesticides, signal molecules for the interaction symbiotic rhizobia with roots, attractants pollinators, protective agents against...
We tested the capability of plants to utilize protein as exclusive source nitrogen. The aim this study was find out how such a nutrition affected plantlet growth, photosynthetic performance, and N assimilation metabolism in tobacco (Nicotiana tabacum L., cv. Petit Havana SR1) grown vitro. Plantlets casein-supplemented (CA) medium were compared plantlets complete Murashige-Skoog (MS) medium, an ammonium-deficient (N1), or nitrate-reduced (N2). In addition, presence absence 1.5 % (m/v)...
β-N-acetylhexosaminidases (EC 3.2.1.52,) are ubiquitous enzymes, present in all organisms. These enzymes catalyze the hydrolysis of N-acetylglucosamine (GlcNAc) or N-acetylgalactosamine (GalNAc) from non-reducing end oligosaccharides, glycoproteins, glycolipids, and other glycoconjugates. The functions these greatly differ between individual organisms, cells compartments.
