“…The plants themselves have quite effective defense mechanisms that prevent viral infection and virus spread. For instance, there are two main types of virus resistance in Solanaceae: extreme resistance and localized hypersensitivity [3]. Extreme resistance provides high resistance to all strains of the virus while localized hypersensitivity is strain-specific.…”

“…Hypersensitive response (HR) is characterized by necrosis and disruption of the virus systemic spread in plants. In potato plants, HR in response to strains PVYC and PVYO of PVY is controlled by potato Nytbr and Nctbr genes, respectively [3,78].…”

“…In most of the studies, PGPM are characterized as microorganisms that activate resistance to a wide variety of herbivores and necrotrophic pathogens by the JA-dependent signaling pathway, leading to the development of induced systemic resistance (ISR). At the same time, SA induces biochemical processes in plants, leading to resistance against biotrophic pathogens, viruses [1,3], and pests (hemiptera and aphids) [92]. The ability of the B. subtilis BS3A25 isolate to reduce the melon aphid Aphis gossipi (CMV vector) population [33] may be due to aphicidal activity of bacteria-produced surfactants [92,93].…”

“…The majority of viruses that infect agricultural plants (at least 450 different species) are RNA viruses [2]. More than 40 of them infect potatoes causing cultivar damage which results in a significant loss in their productivity and deterioration of the tuber quality [3]. It is estimated that about 40% of total crop losses is caused by viral infection.…”

Plant viruses are globally responsible for the significant crop losses of economically important plants. All common approaches are not able to eradicate viral infection. Many non-conventional strategies are currently used to control viral infection, but unfortunately, they are not always effective. Therefore, it is necessary to search for efficient and eco-friendly measures to prevent viral diseases. Since the genomic material of 90% higher plant viruses consists of single-stranded RNA, the best way to target the viral genome is to use ribonucleases (RNase), which can be effective against any viral disease of plants. Here, we show the importance of the search for endophytes with protease and RNase activity combined with the capacity to prime antiviral plant defense responses for their protection against viruses. This review discusses the possible mechanisms used to suppress a viral attack as well as the use of local endophytic bacteria for antiviral control in crops.

“…The yield and quality of potatoes depend on the infection rate with a number of pathogens, including bacteria, fungi, viruses and viroids. Viral infection can cause considerable damage to this food crop (Makarova et al, 2017;Ibragimova et al, 2018). It has been established that it is the viruses that reduce the productive qualities of tubers in 90% cases and only 10% caused by unfavorable environmental conditions, plant nutrition problems and other negative factors (Onishchenko, 1996;Frolova, 1971).…”

Potato, one of the most important food crops in the world, is susceptible to viruses, which reduce its yield and production efficiency. The resistance of potatoes to viral infection is an essential factor in the preservation of the variety’s productive qualities. In addition, there are several ways of selection for recovering and obtaining the initial seed material that is free from viruses for further reproduction in the seed growing of potatoes. It should be noted that in the literature the issues of medium-late potato varieties resistance to viral diseases in the Forest-Steppe zone of Ukraine are not fully covered, which has become the subject of our research. In our studies we used the material obtained by the method of improving selections, as well as using thermotherapy and apical meristem culture. Over the years of reproduction both meristematic and seed material from improving selections, the virus infestation in plants wasn’t changed significantly, provided that all seed growing events were observed. It has been proven that the yield of super-super-elite of Lybid variety is not significantly changed depending on the method of obtaining the initial material. The variety Gorlitsa has higher yield in the plantations formed by clonal propagation. It has been established that the yield of variety Lybid super-elite varies, but not significantly, depending on the method of obtaining the initial material. The variety Gorlitsa has a higher super-elite yield when using the initial material from clonal propagation in breeding nurseries with use of improved selections. Significant influence on the manifestation of the sign, both in the cultivation of super-super-elites and super-elites, has the weather conditions of the year and the biological characteristics of the variety. In 2017, the highest yield of tubers was obtained at Gorlitsa – 3.74·104 kg ha-1, at Lybid the lower yield was 2.43·104 kg ha-1. In 2018, the highest yield of tubers was formed by Lybid variety – 3.50·104 kg ha-1, and the lowest was byt Gorlitsa variety – 2.56·104 kg ha-1.

The influence of the physiological and biochemical parameters of the leaves of 12 potato varieties on the formation, plasticity, and stability of the potato crop has been studied. The experiments were carried out on the territory of the Samara Research Institute of Agriculture – branch of the SamSRC RAS (53°03’ N, 49°25’ E) in the period 2019-2022. Average potato yields varied in the range of 14.2-25.7 t/ha. The highest yield was the first planting year. With an increase in the duration of reproduction, yield losses ranged from 25 to 50% due to a decrease in the mass of tubers. The coefficient of variation in yield varied in the range of 24-60% depending on the genotype. Criteria of ecological plasticity and stability of potato of different genetic origin are such indicators as leaf dryness or its hydration, the content of phenolic compounds in the leaves, the content of lipid oxidation products, and the state of the membranes. The amplitudes of variation of leaf indicators can serve as a measure of plasticity. Adaptive capacity is related to the content of proline, the ratio of membrane lipids and proteins, and the number of stomata.
