“…Nosenko et al . (2021) recently highlighted the potential of using particular stress‐induced plant defence proteins as potential markers for early detection of forest damage and diseases. For plants, the disadvantages of defence proteins are their high costs of biosynthesis and their potential toxicity to the host plant.…”

In their environment, plants are exposed to a multitude of abiotic and biotic stresses that differ in intensity, duration and severity. As sessile organisms, they cannot escape these stresses, but instead have developed strategies to overcome them or to compensate for the consequences of stress exposure. Defence can take place at different levels and the mechanisms involved are thought to differ in efficiency across these levels. To minimise metabolic constraints and to reduce the costs of stress defence, plants prioritise first‐line defence strategies in the apoplastic space, involving ascorbate, defensins and small peptides, as well as secondary metabolites, before cellular processes are affected. In addition, a large number of different symplastic mechanisms also provide efficient stress defence, including chemical antioxidants, antioxidative enzymes, secondary metabolites, defensins and other peptides as well as proteins. At both the symplastic and the apoplastic level of stress defence and compensation, a number of specialised transporters are thought to be involved in exchange across membranes that still have not been identified, and information on the regeneration of different defence compounds remains ambiguous. In addition, strategies to overcome and compensate for stress exposure operate not only at the cellular, but also at the organ and whole‐plant levels, including stomatal regulation, and hypersensitive and systemic responses to prevent or reduce the spread of stress impacts within the plant. Defence can also take place at the ecosystem level by root exudation of signalling molecules and the emission of volatile organic compounds, either directly or indirectly into the rhizosphere and/or the aboveground atmosphere. The mechanisms by which plants control the production of these compounds and that mediate perception of stressful conditions are still not fully understood. Here we summarise plant defence strategies from the cellular to ecosystem level, discuss their advantages and disadvantages for plant growth and development, elucidate the current state of research on the transport and regeneration capacity of defence metabolites, and outline insufficiently explored questions for further investigation.

“…Moreover, Spanic et al [51] determined a lower level of protein in the barley infected by F. graminearum. Nosenko et al [52] indicated that the enhanced level of protein in infected plants is due to the biosynthesis of pathogenesis-related (PR) proteins, antimicrobial peptides (AMPs), and kinases, which alleviate the effects of biotic stress. However, based on our results, these processes were not effective in the wheat exposed to nitrophenols.…”

Organic biostimulators support wheat growth in unfavorable conditions; however, to date, multifactorial assessments of their role in the plant–pesticide–pathogen system have been poorly investigated. The goal of this study was to evaluate the changes in the metabolite profile (protein, carbohydrate, phenolic compounds, acid phosphatases, and amino acids) and the antioxidant potential (antioxidant enzymes) of wheat that is infested with F. culmorum and exposed to humic acids, nitrophenols, and six pesticides. Additionally, the concentration of the mycotoxins in the wheat grain and the dissipation time of the six pesticides in the wheat plants were determined. In this multifactorial experiment, we explored differentiated activities of humic acids and nitrophenols in wheat metabolism during fungal pathogenesis and pesticide protection. Nitrophenols decreased oxidative stress through induced catalase activity. In contrast, humic acids contributed to the highest enhancement of the total level of carbohydrates (27%) in the inoculated wheat. Both biostimulators reduced the mycotoxin concentration (DON, 3-AcDON, 15-AcDON, NIV) by 32% and nitrophenols increased the concentration of amino acids (13%). Unexpectedly, humic acids and nitrophenols shortened the degradation time (DT50) of spiroxamine by up to 60% in inoculated wheat. The overall results of this study provide novel information on the changes in wheat metabolites, antioxidant defense, and pesticide dissipation in the pesticide–biostimulator–pathogen system.

“…The genetic information included in the genome is practically carried out only through proteins, which is why their supremacy as genetic and phylogenetic markers is obvious. Protein traits, as a rule, are inherited by the principle of co-dominance, and genotype analysis is directly possible with the protein phenotype (Konarev et al, 2000;Bojórquez-Velázquez et al, 2021;Nosenko et al, 2021).…”

The genetic resources of plants and animals are the wealth of every country. They are a valuable starting material in the breeding processes of cultivated plants and farm animals. In order to improve the existing varieties of crops and obtain new, valuable varieties, it is very important to document, preserve and enrich their gene pool, while preserving local varieties and forms of crops, it is possible to carry out breeding works. From this point of view, the genetic characterization of beet population varieties cultivated in Armenia and their wild relatives using protein markers is up-to-date and has important scientific and practical significance. It is known that the degree of genetic diversity of a population can be estimated if the protein formulas and their frequency of occurrence in the population are known. The purpose of this research was to evaluate the genetic diversity of beet spread in Armenia, formed during the evolutionary development processes, to passport the wild species and population varieties of beet by using protein markers and offering them as starting breeding material. As a result, the preferred raw material forms were proposed in the breeding works in the direction of increasing yield, sugar level, and resistance to powdery mildew and Cercospora leaf spot diseases. Further cluster analysis will make it possible to select parental pairs. Future beet breeding efforts in the target direction must make use of the genetic and genomic resources available for efficient improvement.
