The ontogenetic and phylogenetic changes in the trypsin-like enzymes expression level in Drosophila melanogaster and D. virilis were found. The genotoxic effects of a number of pesticides were detected on the test objects. Different efficiency of the test system "line 109 611 D. melanogaster" components was shown: the repair test did not reveal the mutagenic effect of xenobiotics, and wing test showed the presence of mutations. It has been found that the effect of some modern anthropogenic factors may reduce the advantages of polyploidy. The beneficial effects of conventional and genetically modified soybeans on the fecundity of D. melanogaster and a neutral effect on the viability of the flies were shown. The negative effect of monoterpenes and the positive effect of medicinal basidiomycetes on the fitness components of flies of the C-S line and the vg line with a reduced viability, has been revealed. The strains of ONU F101 and ONU F102 Ganoderma lucidum suppresses opportunistic microorganisms. Fusarium metabolites reduce the mitotic index of the cereal meristem and increase the proportion of cells with aberrations. The peculiarities of the expression of peroxidase, SOD and esterase in salt-resistant wheat-foreign hybrids for the actions of NaCl have been elucidated. The analysis in families selected for resistance to fungal diseases showed qualitative differences in the spectra of multiple molecular forms of enzimes. The individual families of hybrids are more resistant than parental forms by juvenile resistance to B. sorokiniana and F. graminearum. The influence of the nutrient medium on the expression of A. auricula-judae carboxyl esterase was established: up to 10 isoforms are expressed, two of which are present in all variants, which indicates their adaptive importance. The tendencies of correlative connections between the Rht short-stemming genes in the wheat wheat genotype and plant resistance to osmotic stress have been established. The use of complex nutrient media for germinating seeds under osmotic stress does not provide high-precision results. The use of 1% NaCl solution provides screening for resistance to salinity in vitro. The genotypes of common wheat varieties of the Mironovskaya breeding by Ppd genes were analized and their relationship with sensitivity to the photoperiod was shown.
