Investigate the general ability of different phenotypes of Trifolium repens L. according to the pattern of white marking on a leaf to the concentration of mobile forms of iron (Fe), manganese (Mn), copper (Cu) and zinc (Zn). Methods. Determination of Fe, Mn, Cu and Zn content in Trifolium repens L. in soil and leaves was performed by atomic absorption method using ICP-AES analyzer. Collection of leaves and selection of soil samples for research was carried out in 2021 during the period of mass flowering of Trifolium repens L. from randomized areas of pasture. Identification of drawings of white marking on a leaf  was carried out according to the method of I. T. Paponova and P. Ya. Schwartzman, using the tables of J. L. Briubecker. To characterize the biogenic migration of Fe, Mn, Cu and Zn and biogeochemical features of different phenotypes of Trifolium repens L. used methods developed by I. A Avessalomova. Results. In the sample of leaves of Trifolium repens L. from pasture 5 phenotypes (O, A, AH, BH, С) were found, the genotypes of which are formed by a series of 6 alleles of the V gene. The most common was the phenotype BH, the smallest was the share of the phenotype AH. The highest total ability to concentrate the mobile forms of Fe, Mn, Cu and Zn was found by phenotype BH, the lowest – phenotype A. Conclusions. Phenotypes O, A, AH, BH, С differ in biogeochemical activity in terms of the concentration of mobile forms of Fe, Mn, Cu and Zn. According to the general ability to accumulate these elements, these phenotypes form the following descending order: BH >O >С >AH >A.","PeriodicalId":12181,"journal":{"name":"Faktori eksperimental'noi evolucii organizmiv","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83476826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Investigate the influence of treatment of maize plants with restrictive biological products on the formation of productivity of lines - parent components to optimize the elements of cultivation technology. Methods. 3-factor field experiment; measuring and weighing - to determine the structure of the crop; methods of mathematical statistics (analysis of variance, rectilinear and curvilinear correlation and regression). Results. Studies have shown that for the maximum manifestation of the sign \"mass of 1000 grains\" the optimal density is 70,000 plants ha-1. The increase in yield is positively influenced by the increase in the weight of 1000 seeds, which is due to both the genotype of the lines and the use of biologically active drugs Bio-gel, Helafit-combi. With the use of the drug Bio-gel laboratory germination increased by an average of 1.5 %, with the use of the drug Helafit-combi seed germination increased by 2.4 %. Conclusions. The maximum yield of the parent component DK 247 was observed at a density of 80 thousand plants/ha and treatment with the drug Helafit-combi - 4.89 t/ha.

The aim of research was to investigate influence of water deficit in soil on morphology and productivity of bread winter wheat plants (Triticum aestivum L.). Methods. Wheat plants cultivars Podolyanka and Natalka were grown under optimal conditions until the earing-flowering phase, after that the experimental plants were transferred to drought regime for 8 days. The optimal supply of water was restored to the end of vegetation. The leaf surface area, the mass of internodes and ear were measured during the experiment. Ripened plants were analyzed by the yield structure. Results. It is established that the effect of water deficit in the critical earing-flowering phase of ontogenesis caused decreasing in the leaf surface area, mass of internodes and ear, weight of 1000 grains in both Podolyanka and Natalka cultivars. However, number of grains decreased only in cultivar Podolyanka under drought. Conclusions.

The genus Aconitum is represented in the Carpathian region by a significant number of endemic species. Some of these species, in particular A. pseudanthora and A. jacquinii, are included in the Red List of Ukraine. However, their taxonomic status and consequently the importance of conserving their natural resources remain uncertain. DNA barcoding techniques, e.g., the application of molecular markers based on variable regions of the chloroplast genome can help clarify these questions. Methods. DNA isolation, PCR amplification, sequencing of PCR products, phylogenetic analysis. Results. The psbA-trnH intergenic spacer region of A. pseudanthora and A. jacquinii specimens from Western Ukraine was amplified and sequenced. It is shown that the spacer sequences for these two species are identical, but differ in short indels and nucleotide substitutions from the psbA-trnH sequences of A. anthora s.l. specimens from Western Europe and China. Phylogenetic analyzes showed the phylogenetic affinity of the members of the A. anthora complex to the subgenus Lycoctonum. Conclusions. The use of the psbA-trnH intergenic spacer region for DNA barcoding makes it possible to unambiguously distinguish samples of A. jacquinii and A. pseudanthora from western Ukraine from samples of A. anthora s.l. of other geographical origins. The results obtained confirm the reticular nature of the evolution in the genus Aconitum.","PeriodicalId":12181,"journal":{"name":"Faktori eksperimental'noi evolucii organizmiv","volume":"2012 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86363772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods. Methods of in vitro and ex vitro cultivation of plants, the method of free proline detection with the use of ninhydrin. Results. It is shown that under in vitro conditions of free proline content in plants is dependent on light regime of their cultivation and the source of carbon in the composition of nutrient medium. The increased intensity of luminous flux within the range of photosynthetically active radiation (PAR) from 85 W/m2 to 100 W/m2 and 1.92 times raised share of red range waves in the light spectral composition in variant 2.1 (intensity of the luminous flux in the PAR range is 100  W/m2, the waves correlation of blue (Eb): green (Eg): red (Er) ranges = 25 % : 27 % : 48 %) causes 11.5–37.1 %  increased amount of free proline in plants in vitro cultivated on nutrient media supplemented with sucrose.

The analysis of water balance of plants in vitro cultivated on mannitol under light conditions of 2.1 variant and the plants in conditions of natural growth doesn’t show any considerable distinctions in values of transpiration intensity, water deficit, general water content. The process of adaptation of plants in vitro to conditions ex vitro is accompanied by a change of proline content in leaves with dependence on water deficit in the substrate and light conditions of growing.

It is known that in cancerous cells of childhood tumors the pathological changes often include inactivation of the TP53 and RB-E2F1 cellular pathways. One of the proteins controlling the latter pathway is MRPS18-2, that belongs to a family of mitochondrial ribosomal proteins MRPS18. It is important, to study the stability of proteins of this family and their ubiquitination, that might help to conclude about the functional properties of these proteins and their role in cell transformation. Methods. Cloning of cDNA in FLAG vector for expression of fusion proteins, transfection of human tumor cells MCF7, study on cellular localization of MRPS18 family proteins and their ubiquitination by fluorescence microscopy, using specific antibodies. Results. The FLAG-MRPS18-1 and FLAG-MRPS18-3 fusion proteins are partially co-localizing with the HA-Ub fusion protein in the cytoplasm of MCF7 cells. The FLAG-MRPS18-2 protein is localized also in the nucleus. Conclusions. Nuclear localization of the FLAG-MRPS18-2 protein may indicate its additional functions in the cell: due to the interaction with the RB protein and the positive effect on mono-ubiquitination of histone H2B, the MRPS18-2 protein may be involved in the regulation of chromatin structure.","PeriodicalId":12181,"journal":{"name":"Faktori eksperimental'noi evolucii organizmiv","volume":"49 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74174639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the research was to obtain the zinc complex hypoxanthine-9-riboside and to study its effect during γ-irradiation on the biosynthesis of chlorophylls, carotenoids and on the release of chromosome aberrations in anaphase root hair cells in wheat seedlings. Methods. The zinc complex was obtained by direct interaction of zinc chloride – ZnCl2 with hypoxanthine-9-riboside. X-ray phase analysis and thermogravimetric measurements of the obtained complex were carried out. Before irradiation, seeds of durum wheat Triticum durum L. from a 60Co source were treated with a zinc complex with hypoxanthine-9-riboside at concentrations of 0.1; 0.01; 0.001%. Structural changes in chromosomes were determined in the initial and final stages of anaphase. Determination of chlorophylls and carotenoids was carried out according to Shlyk. Results. g-irradiation at doses of 50, 100 and 200 Gy has a significant effect on the content of green pigments and carotenoids in wheat seedlings. Under the action of g-irradiation, the content of chlorophyll decreases more than carotenoids. With an increase in the dose of radiation, a slight increase in the content of carotenoids is noted. In all variants, chromosomal abnormalities were found: the formation of fragments in metaphase and anaphase, bridges in anaphase, chromosome delays, uneven division of chromosomes. Conclusions. For the first time, it was found that the Zn (II) complex of hypoxanthine-9-riboside at the indicated concentrations significantly reduces the damaging effect of γ-irradiation, helps to eliminate abnormalities in mitotic division in wheat root hair cells.","PeriodicalId":12181,"journal":{"name":"Faktori eksperimental'noi evolucii organizmiv","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75833718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
