A method for fabrication of a novel type optical fiber with dispersion varying along the length is described. The takes into account calculated dependence on core diameter measured profile preform and desirable length. main parameters drawn are theoretically studied experimentally measured. fibers great interest nonlinear optics. Such applications fibers, such as high-quality soliton pulse compression, pulsewidth stabilization through compensation losses, generation high-repetition-rate...
Endophytic plant-growth-promoting microorganisms can protect plants against pathogens, but they have rarely been investigated as potential biocontrol agents and triggers of induced systemic resistance (ISR), regulated by phytohormones, viruses. We studied the role endophytic strains Bacillus subtilis 26D B. Ttl2, which secrete ribonucleases in induction tomato plant potato virus X Y a greenhouse condition. The endophytes reduced accumulation viruses plants, increased activity recovered fruit...
Viral diseases and their damage causing significant loss to economically important crops have increased by several folds during the last decade. All conventional approaches aren't able eradicate viral infection. Therefore, there is a need look for efficient eco-friendly disease preventive measures. The genomic material of majority deleterious viruses higher plants RNA. One possible measures control use ribonucleases (RNases) which can cleave RNA in genome. Based on this, we investigated...
The use of biocontrol agents based on endophytic bacteria against phloem-feeding insects is limited by a lack knowledge and understanding the mechanism action endophyte community that makes up plant microbiome. In this work, mechanisms additive strains B. subtilis 26D 11VM resistance bread spring wheat greenbug aphid Schizaphis graminum, was studied. It shown secreted lipopeptide surfactin phytohormones cytokinins, produced iturin auxins into cultivation medium. Both their lipopeptide-rich...
Ethylene, salicylic acid (SA), and jasmonic are the key phytohormones involved in plant immunity, other hormones have been demonstrated to interact with them. The classic phytohormone cytokinins important participants of defense signaling. Crosstalk between ethylene has not sufficiently studied as an aspect immunity is addressed present research. We compared expression genes responsible for hormonal metabolism signaling wheat cultivars differing resistance Stagonospora nodorum response their...
Abscisic acid (ABA) is not only important for plant responses to abiotic stresses, but also plays a key and multifaceted role in immunity. In this work, we analyzed the of ABA development resistance/susceptibility wheat (Triticum aestivum L.)–Stagonospora nodorum Berk. pathosystem, which includes recognition necrotic effectors (NEs) pathogen by corresponding susceptibility genes. We studied interaction S. SnB isolate, produces two NEs, SnToxA SnTox3, with three genotypes having different...
Bacillus subtilis 26D is a plant growth-promoting endophytic bacteria capable of inducing systemic resistance through the priming mechanism, which includes genome reprogramming and phenomenon RNA interference (RNAi) microRNA (miRNAs). The phloem-feeding insect bird cherry-oat aphid Rhopalosiphum padi L. serious pest that causes significant damage to crops throughout world. However, function miRNAs in response infestation remains unclear. results this work showed B. stimulated wheat plants,...
Hypothermia, drought, salinity and heavy metals are the most widespread stress factors negatively affecting plant growth development. Plants respond to these on molecular, cellular, physiological levels through complicated mechanisms of signal perception transduction, subsequently inducing various defense mechanisms. Transcription controlling expression numerous proteins significant abiotic reaction regulators. Mainly, negative environmental influence activates AP2/ERF, WRKY, MYB, NAC, bZIP...
Virulence factors of the pathogen Stagonospora nodorum Berk. are numerous necrotrophic effectors (NEs) (SnTox), which interact with products host susceptibility genes (Snn), causing development disease. In this study, 55 accessions bread spring and winter wheat were screened for sensitivity to NEs SnToxA, SnTox1, SnTox3 using different isolates S. nodorum. studied panel wheat, 47 modern commercial cultivars grown in Russia 8 historic from N. I. Vavilov Institute Plant Genetic Resources...
Reactive oxygen species (ROS) play a central role in plant immune responses. The most important virulence factors of the Stagonospora nodorum Berk. are multiple fungal necrotrophic effectors (NEs) (SnTox) that affect redox-status and cause necrosis and/or chlorosis wheat lines possessing dominant susceptibility genes (Snn). However, effect NEs on ROS generation at early stages infection has not been studied. We studied stage various genotypes with S isolates -Sn4VD, SnB, Sn9MN, carrying...
The fungus Stagonospora nodorum Berk. is the causative agent of Septoria blotch (SNB) wheat. most important factors virulence include numerous fungal necrotrophic effectors (NEs) encoded by SnTox genes. They interact with matching products host susceptibility genes (Snn). SnTox-Snn interactions are mirror images classical gene-for-gene and lead to development disease. We have studied SnTox3-Snn3 interaction, resulting in infection on leaves formation extensive lesions. mechanism SnTox3...
Materials and methods: a prospective non-randomized pilot multicenter study of the informativeness clinical significance hemostasis laboratory tests in 1210 patients with COVID-19 disease course, including favorable unfavorable outcomes, was performed. Hemostasis assessed using clotting D-dimer concentration, thromboelastography (TEG) thrombodynamics (TD). Results: comparison parameters picture showed that 75% have pronounced activation plasma coagulation system upon admission to hospital....
The greenbug aphid Schizaphis graminum Rond. causes a significant loss of the grain harvest. Therefore, to improve plant resistance aphids is one topical tasks. problem creating varieties resistant phloem-feeding insects quite urgent, since mechanisms procuring plants are not fully understood. Nevertheless, modern literature describes some associated with changes in redox state colonized plants. Besides, attention being increasingly focused on study that underlie inducible wheat and...

The greenbug aphid Schizaphis graminum causes significant damage to wheat crops, so increasing plant resistance against aphids is one of the primary tasks. It has been shown that colonization by trigger both jasmonate/ethylene- and salicylate-dependent defense responses in plants. Ethylene produced when insects attack. suggested ethylene plays an important role inducing pests, but mechanism action not fully understood. In this work, induction hormonal signaling pathways plants during...
Beneficial endophytic bacteria can suppress the development of insect pests through direct antagonism, with help metabolites, or indirectly by induction systemic resistance regulation hormonal signaling pathways. Lipopeptides are bacterial metabolites that exhibit antagonistic activity against many organisms, including insects. Also, lipopeptides able to trigger induced (ISR) in plants harmful but physiological mechanisms their action just beginning be studied. In this work, we studied ten...
