The Influence of Chitosan Derivatives in Combination with Bacteria on the Development of Systemic Resistance in Potato Plants with Viral Infection and Drought.

Viral diseases of potatoes are among the main problems causing deterioration in the quality of tubers and loss of yield. The growth and development of potato plants largely depend on soil moisture. Prevention strategies require comprehensive protection against pathogens and abiotic stresses, including modeling the beneficial microbiome of agroecosystems combining microorganisms and immunostimulants.

Stimulation of the Defense Mechanisms of Potatoes to a Late Blight Causative Agent When Treated with Bacteria and Chitosan Composites with Hydroxycinnamic Acids.

is, worldwide, one of the main causal agents of epiphytotics in potato plantings. Prevention strategies demand integrated pest management, including modeling of beneficial microbiomes of agroecosystems combining microorganisms and natural products. Chitooligosaccharides and their derivatives have great potential to be used by agrotechnology due to their ability to elicit plant immune reactions.

Role of Endogenous Salicylic Acid as a Hormonal Intermediate in the Bacterial Endophyte -Induced Protection of Wheat Genotypes Contrasting in Drought Susceptibility under Dehydration.

Endophytic is a non-pathogenic beneficial bacterium which promotes plant growth and tolerance to abiotic stresses, including drought. However, the underlying physiological mechanisms are not well understood. In this study, the potential role that endogenous salicylic acid (SA) plays in regulating endophytic -mediated drought tolerance in wheat ( L.

[Genome Editing in Species of the Tribe Triticeae with the CRISPR/Cas System].

The tribe Triticeae includes important agricultural crops, such as bread wheat, durum wheat, barley, rye, and triticale. Research in the field of reverse genetics and genetic engineering of Triticeae received a new impetus as the CRISPR/Cas genome editing system came into broad use. The review describes and analyzes the data on recent advances in genomic editing of cultivated plants of the tribe Triticeae and tools used in the field.

Visualization of different anatomical parts of the enucleated human eye using X-ray micro-CT imaging.

Micro-CT visualization allows reconstruction of eye structures with the resolution of light microscopy and estimation of tissue densities. Moreover, this method excludes damaging procedures and allows further histological staining due to the similar steps in the beginning. We have shown the feasibility of the lab-based micro-CT machine usage for visualization of clinically important compartments of human eye such as trabecular outflow pathway, retina, iris and ciliary body after pre-treatment with iodine in ethanol.

The ARGOS-LIKE genes of Arabidopsis and tobacco as targets for improving plant productivity and stress tolerance.

A small family of ARGOS genes encodes transmembrane proteins that act as negative regulators of ethylene signaling. Recent studies show that ARGOS genes are involved in the regulation of plant growth under the influence of stress factors. However, the role of ARGOS genes in this process is poorly known.

[Efficiency of therapeutically applied physical factors for vibration disease caused by exposure to local vibration (review of literature).].

Important role in treatment and prophylaxis for vibration disease due to local vibration is played by physical factors. If high frequency components prevalent in occupational vibration, treatment with electric therapy, laser, magnetic fields, lymphatic drainage, hydrotherapy provides influence on leading chains of systemic microangiopathies pathogenesis - dysbalance of regulation influences by vegetative nervous system, vasoconstriction and intravascular changes, vascular permeability and microcirculation disorders. If low frequency coomponents prevalent in occupational vibration, treatment of polyneuropathies and locomotory disorders incorporates trophic processes activation: transcranial electroanalgesia, surface application of mineral waters, manual and subwater massage, ozone therapy, local spark discharges, peloids.

[Relationship between the aggressiveness and catalase activity of Septoria nodorum berk. in wheat].

A comparative study of hydrogen peroxide (H202) generation, the character of a fungal catalase gene expression, and the catalase activity in wheat plants, infected with Septoria nodorum Berk. strains differing in their aggressiveness, has been carried out. The decreased intensity of H202 accumulation in infected tissues, influenced by an aggressive S.

[Salicylic and jasmonic acids in regulation of the proantioxidant state in wheat leaves infected by Septoria nodorum Berk].

Influence of mediators of the signal systems of salicylic (SA) and jasmonic (JA) acids and their mixture on reactive oxygen species' (ROS) (superoxide radical O2*- and H2O2) generation and activity of oxidoreductases (oxalate oxidase, peroxidase and catalase) in leaves of wheat Triticum aestivum L. infected by Septoria leaf blotch pathogen Septoria nodorum Berk. has been studied.
