To examine the presence and level of viral infection, field observations of the soybean crops in the Cherkassy, Vinnitsa and Kyiv regions have been performed. It was established that the diseases in the soybean plants growing in the examined areas have been caused by two major viruses--SMV (Soybean mosaic virus) and BYMV (Bean yellow mosaic virus). The(More)
This paper analyzes the genetic basis and modern conception of molecular mechanisms of recognition of pathogens, mainly viruses, by plants. The importance of signal systems and their key factors in plant organisms are discussed. The possible role of different elicitors in signal transduction processes is reviewed.
Computational analysis of codon usage bias and spontaneous nucleotide substitutions in six strains of soybean dwarf virus was performed. It was shown that synonymous codon usage in the virus genes varies widely depending on the gene, gene overlapping, codon, codon's two first nucleotides, mononucleotide context located upstream and downstream of the codon,(More)
Modern conceptions of the molecular and genetic mechanism of resistance of plants to viruses are analyzed. Two strategies of antivirus protection of plants, that due to an R-gene mediated mechanism and that due post-transcription gene silencing (RNA silencing), are considered. Examples of the use of protective mechanisms for the purpose of creating(More)
A computer search for position-linked identical nucleotide sites in sequences of promoter regions of subgenomic RNA and coat protein of fifteen tobamoviruses was performed. It was discovered that promoters of three TMV strains tested as well as of tobacco mild green mosaic virus and turnip vein-clearing virus contain the nine-nucleotide sites gattcgttt or(More)
Elucidation of the factors underlying nucleotide substitution types and rates in genomes is of significance for improving the prevalent models for molecular evolution, and is essential in studying the evolution process, distinguishing the coding and noncoding RNAs, identifying biologically significant motifs such as replication signals, control regions and(More)
This paper gives a brief overview of the recent ideas about programmed cell death including apoptosis in animals and plants. Comparison of these processes in animal and plant cells in terms of physiological features has been presented. Necrosis as a form of pathological, not genetically programmed cell death has been characterized. Reflections about the(More)
Recent insights into virus-host interaction have been compiled in this review, focusing on the genetic basis and the modern conception of the molecular mechanisms of pathogen (mostly viral) recognition by plants. The significance of plant signal transduction systems and their key factors are discussed. The possible role of different elicitors in signal(More)
Changes in content of proteins and carbohydrates of sensitive and supersensitive tobacco and datura plants and their antiviral and hemagglutinating activity under tobacco mosaic virus infection were investigated. It was shown that the content of these substances was increased on early stages of virus infection in hypersensitive plants. Antiviral and(More)
