Subsidy Entrepreneurship and Nigeria’s Economic Development
Authors: Opuala-Charles Silva , Oshilike Ijeoma Victoria
Published: September 2023

The research delved into the impact of subsidy entrepreneurship on the economic development within Nigeria throughout the span from 2012 to 2021, utilizing annual time series data. The evaluation of stationarity was conducted through the Augmented Dickey Fuller test, while the estimation of parameters was undertaken using the Autoregressive Distributed Lag (ARDL) methodology. The findings unveiled a persistent and long term relationship among the variables. The test outcomes reveal that all the variables exhibit stationarity upon initial differencing, surpassing the 5% level of significance. The results show an increase in fiscal deficit as a proxy for subsidy entrepreneurship leads to a decrease in economic development. The result also pointed out an increase in gross national income leads to increase in economic development. The results have obvious policy implications for Nigeria. Nigeria must do away with subsidy entrepreneurs which are corruptly enriched through fiscal deficit responsible for the infrastructural gap and fueling poor human development index in Nigeria. Keywords: Subsidy entrepreneurship; Economic Development; Human Development Indicator; Fiscal Deficit

Published: September 2023

Hydatid is a global disease and affects almost all organs of the body, liver being the most common. Patients with hydatid disease often present as a therapeutic challenge since there is no specific consensus regarding the optimal management. The complete therapy of hydatid disease should aim to eliminate the parasite to cure the disease. The first and important step should be prevention of the disease by implementation of safe hygienic practices. Medical and surgical management go hand in hand with surgery being the treatment of choice, controversy still exists about the most appropriate surgical approach. Surgical management remains the gold standard for liver hydatid cyst, however individualization of treatment modality depending upon the type, number, location, recurrent disease and complications is recommended.

Monogamia, pandemia y disidencia relacional: notas desde Brasil
Authors: Pérez Navarro Pablo
Published: September 2023

El imperativo cultural de la monogamia impregna toda la arquitectura jurídica del Estado y, al mismo tiempo, la excede, saturando las relaciones sociales de formas no siempre evidentes. A partir de ese presupuesto, este trabajo se centra, geográficamente, en Brasil y, temporalmente, en el contexto abierto por la pandemia de covid-19, con el objetivo de defender la hipótesis de que la monogamia se ha visto reforzada en cuanto principio organizador del campo de la sexualidad y de las relaciones de parentesco durante el episodio pandémico. El análisis propuesto pretende alertar, además, sobre las formas en que las normas de excepción implementadas durante las crisis pandémicas se sedimentan en el cuerpo social, pasando así a formar parte constitutiva del orden público.

Published: September 2023

Abstract: This paper aims to discuss the role of Christian parents in shaping the character of children facing moral degradation. The current phenomenon of children's delinquency leads to moral degradation. This is evident in the fact that children are no longer victims but also perpetrators. The emergence of cases of vandalism, brawl, harassment, rape and even murder committed by children, shows the weakness of moral education in Indonesia. There are two main factors that influence the internal and external. Therefore there is a need for synergy between parents, teachers and the community to educate children. In addition to moral education in the family and community, the school is a partner of parents to educate and instill moral values for children in school. Parents have a big part in shaping the character of children to become moral individuals. This research is here to help parents by offering steps to be able to teach moral values to children. The author uses descriptive methods so that readers can see a picture of the results of research as a whole. The role of parents to overcome the moral degradation of children in the family includes education from the mother's womb, the way a child learns in the family and the five stages of acquisition of values and behavior.
Sejarah Misi C&MA Sebagai Implementasi Pertumbuhan Penginjilan Pada Masa Kini
Authors: Iskandar Iskandar , Ado Ado
Published: September 2023

The Cristian and Missionary Alliance (C&MA) adalah organisasi yang dibentuk oleh salah satu tokoh misi yaitu Albert Benjamin Simpson. Sekitar pada tahun 1897, Simpson mendirikan dua buah organisasi The Cristian Alliance (Perserikatan Kristen), dan The Evangelical Missionary Alliance (Perserikatan Injil untuk Pengutusan ke Luar Negeri). Kedua misi ini digabung menjadi The Cristian and Missionary Alliance.  Sejarah C&MA sebagai implikasi menjadi salah satu faktor utama mendorong pertumbuhan gereja melalui penginjilan. Penginjilan adalah usaha memberitakan kasih Allah melalui Yesus Kristus dalam kuasa Roh Kudus yang dilakukan oleh umat Allah, supaya semua orang yang percaya kepada-Nya tidak binasa melainkan beroleh hidup yang kekal (Yoh. 3:16). Metode yang digunakan peneliti ialah metode deskriptif.  Metode deskriptif adalah metode yang dipakai untuk menyelidiki suatu masalah melalui objek atau subjek berupa orang, lembaga, masyarakat dan yang lainnya. Hasil penelitian ini menunjukkan bahwa pertumbuhan penginjilan masa kini harus mengakui Yesus sebagai Juruselamat, dan berjiwa misi atau menyadari panggilan untuk bermisi. Amanat Agung ini diberikan kepada setiap orang percaya, dan bukan saja kepada para pemimpin gereja.

Published: September 2023

This research examines theologically the expressions of Adam and Christ in Paul's theological perspective. This is quite interesting to study, and the purpose of this research is to clarify Paul's intention when he felt this way in his letter. Researchers used qualitative methods, especially literature or literature review in this study. First, the theological emphasis of the expressions of Adam and Christ is to state about Adam's disobedience and vice versa Christ's obedience. Second, the emergence of the phrases Adam and Christ in Paul's letters will create a significant and striking difference between the first Adam who brought sin to the world and the second Adam, namely Christ who brought life to the world. Third, this phrase also wants to emphasize how well the quality of the second Adam is much higher and nobler than the quality of the first Adam. That is why, everyone who has been born again in the second Adam (namely Christ) will experience eternal life with the true source of life.

Doping is the action or substance use which is prohibited by international regulation. Why do they dope when they already know that it is prohibited. Athletes who dope are seeking to gain a competitive advantage over their rivals. But athletes seek to gain competitive advantages in numerous ways & many of these are not banned. The consequences of doping are health, social, financial and legal problems. The consequences of health are physical and mental problems. Surely, most of the players and populations think that doping should be prohibited. As it is against the defined rules & laws governing sport. It is unfair and goes against the level playing field ideal. The World Anti-Doping Code (WADA Code) states that “Anti-doping programs seek to preserve what is intrinsically valuable about sport.” Doping, like no other issue, hits athletes where it hurts: at their one shot at glory, at their own opportunity of a gold medal. That is why we must continue to work together to protect clean athletes.
Acercamiento a la reflexión política de mujeres mexicanas
Authors: Góngora Cervantes Vanessa
Published: September 2023

El pensamiento político es una actividad intelectual que deja mani­fiesta la forma en que las personas se relacionan entre sí y con las instituciones políticas, lo que permite la comprensión de su expe­riencia y el entorno. Realizar un acercamiento a la reflexión polí­tica de las mujeres nos permite visibilizar su realidad, no solo como fotografía del contexto sociohistórico en el que vivieron, sino que nos acerca a sus referencias intelectuales, sus deseos y expectativas de cambio para alcanzar derechos que entonces se les negaban, o de permanencia de un orden de género que, entendían, les favo­recía y debía permanecer. Más allá de la excepcionalidad que comúnmente ha acompañado el abordaje de las pensadoras, nues­tro propósito es colocarlas en las coyunturas sociales y políticas que les fueron favorables o limitantes, considerar sus condiciones de privilegio u opresión, la existencia o ausencia de nexos con personajes políticos o la existencia de redes de apoyo de mujeres. Este libro hace una invitación a recuperar el testimonio de mujeres mexicanas que, a pesar de la exclusión del espacio de di­sertación política por su condición de género, encontraron res­quicios para exteriorizar sus ideas y posicionarse respecto a problemas sociales y transformación de las instituciones políticas.

The problem of increasing the bearing capacity of foundations is always an urgent task in modern geotechnical construction. It is of particular importance when building on slopes cut by ravines. As a rule, construction on slope surfaces due to the discharge of filtration flows in the form of springs is always a problematic measure. Hydrogeological processes often bring rugged surfaces intended for the construction of objects into an unstable state, leading them to landslides. Thus, the safe erection of buildings and structures in such areas is always accompanied by the simultaneous erection of retaining buried building structures. The most competitive retaining structures are monolithic reinforced concrete corner retaining walls erected on bored piles and fixed with ground anchors. The article gives examples of the use of ERT bored piles (RIT, FORST, ERST) and ERT ground anchors.

Several approaches have already been presented for providing solutions to this type of problem, based on the life cycle of the attack. In recent times, some Machine Learning practices have been implemented in an attempt to ensure improvements in the ability to find and mitigate these threats.
LECTURAS DEL INFORME DE LA COMISIÓN DE LA VERDAD. POSIBILIDADES PARA LA CONVIVENCIA ESCOLAR
Authors: Rojas Pacheco José Alejandro
Published: September 2023

The text addresses the complexity of the current situation in Colombia, a country at a critical moment of social and political change after more than half a century of armed conflict. The signing of the peace agreement with the FARC-EP in 2016 is highlighted as a crucial milestone, although not without challenges, including the reintegration of former combatants and the security of the signatories. The creation of the Commission for the Clarification of Truth, Coexistence, and Non-Repetition is mentioned as an attempt to tell the complete history of the conflict and its victims, facing political obstacles such as the stance of President Iván Duque. The text also focuses on the importance of education for peaceful coexistence, especially within educational communities. It emphasizes the need to review and update school curricula to include a more complete and contextualized history of Colombia, from its history of violence to its struggle for peace. Additionally, it addresses the importance of challenging social norms that perpetuate violence and conflict, such as gender stereotypes and bullying. The role of youth leadership in building a new narrative is also discussed, as well as the active participation of young people in public debate about the country's future. The article underlines the need to remember and honor the slain social leaders, as well as to understand the deeper roots of conflict that include systemic violence and drug trafficking. It suggests that truth and justice are imperatives for coexistence and that society must strive for truth-seeking through different mechanisms such as coexistence committees and programs like Hermes. Additionally, it points to creativity and literature as ways to resignify the past and construct new narratives of coexistence. In summary, the text offers a multifaceted analysis of social and political change in Colombia, highlighting the complexity of transitioning from a state of prolonged conflict to a more peaceful and equitable situation. It proposes a series of strategies and approaches to address these challenges, from the educational system to public participation, with truth and justice as pillars for coexistence.

Cytogenetic disorders of winter wheat root meristem cells under the action of moderate and high concentrations of N-nitroso-N-methylurea
Authors: Yakymchuk R. A.
Published: September 2023

Aim. To study the frequency and spectrum of the cytogenetic disorders in Triticum aestivum L., induced by the effect of moderate and high concentrations of N-nitroso-N-methylurea. Methods. The seeds of winter wheat of cultivars Albatros odeskyi and Zymoiarka were treated with water solution of N-nitroso-N-methylurea in such concentrations as 0.005 %, 0.01 %, 0.025 %. A cytogenetic analysis of the cells of a root meristem was made with help of an anatelophase method. Results. The frequency of mitoses with chromosome aberrations amounted to 2.74–23.05 %, and it depended on the concentration of a mutagen and a plant genotype. A significant increase of the frequency of the aberrant cells was recorded as a result of the effect of the mutagen in the concentration 0.025 %, which was associated with a radiometric impact caused by the influence of a chemical mutagen in a high concentration. The spectrum of cytogenetic disorders contained mostly acentric fragments, the bridges of a chromatid type and the chromosomes which lagged behind. As the super-mutagen concentration increased, the spectrum expansion of the cytogenetic disorders took place at the expense of the even acentric fragments, micro-nuclei and acentric rings. Conclusions. The frequency of the chromosome aberrations, induced by the effect of NMU, exceeds the control level by 3.5–39.7 times, and it depends directly on the concentration of a chemical mutagen. N-nitroso-N-methylurea in the concentration equal to 0.025 % shows a radiometric effect which classifies a mentioned amount of the concentration of a super-mutagen as a high one. A serious increase of the indicator of the number of aberrations per aberrant cell appeared to be typical only when it was under the effect of a chemical mutagen in the highest concentration.

Authors: Dankevych L. A. , Zarudniak M. I.
Published: September 2023

Aim. For the purpose of correct species and internal identification of isolated strains of bacteria that cause walnut leaf spotting, molecular biological and genetic detection of their ability to synthesize the phytotoxin syringomycin have been carried out. Methods. It has been used microbiological and molecular genetic (PCR) methods. Results. The presence of syringomycin (syrD) phytotoxin secretion genes was established in isolated strains of walnut leaf spot pathogen and the typical strain of Pseudomonas syringae pv. syringae UCM B-1027Т. Biotesting of the ability to synthesize syringomycin by these strains revealed the similarity of the antagonistic action of the strains isolated from walnut and the typical strain of Pseudomonas syringae pv. syringae UCM B-1027T, which indicates their ability to synthesize lipodepsinopeptide phytotoxin – syringomycin. Conclusions. Based on the results of the previous researches and presented in this work, strains isolated from walnut were identified as a members of species Pseudomonas syringae pv. syringae.
Androgenic response of spring barley (Hordeum vulgare L.) varieties and lines – sources of high grain protein content
Authors: Bilynska O. V. , Shelyakina T. А.
Published: September 2023

Aim. Protein content is known to be one of the most important characters of grain quality. Investigation was aimed to determine the capability to haploid production in anther culture in vitro of spring barley accessions which are the sources of high protein content in grain. Methods. Infrared spectroscopy was used for evaluation of variability of barley genotypes in protein content. Anthers isolated from cold-pretreated spikes were cultivated on agar solidified nutrient medium containing N6 macro-and MS micronutrients, physiologically active substances and maltose (9.0 %). Results. Three years testing showed that mean grain protein contents in six spring barley accessions varied from 12.6 to 19.1 %. Commercial variety Yavir, accessions IR06605 and DD-21 from germplasm collection of the National Plant Gene Pool of Ukraine were selected as genotypes with a stable expression of this char-acter. Response to androgenesis in vitro varied from 6.9 to 45.9 % of morphogenic anthers and from 0.64 до 14.7 green plants per 100 cultivated anthers in dependence of genotype and donor plant growth conditions. Conclusions. Because of association between high protein content in grains and a relatively high androgenic response, varieties Velikan and Yavir were considered to be the most valuable ones for use in spring barley breeding for improvement of protein content via anther culture in vitro.

Authors: Zhuk O. I. , Stasik O. O.
Published: September 2023

Aim. The aim of the work was to study the realization of the productive potential of bread winter wheat plants under drought (Triticum aestivum L.). Methods. Wheat plants cultivars Bogdana and Perlina Podyllja were grown under optimal conditions until the earing-flowering phase, after that the experimental plants were transferred to drought regime for 8 days. Optimal water supply was restored to the end of vegetation. Leaf surface area, mass of shoot and grains were measured during the experiment. Ripened plants were analyzed by the yield structure. Results. It was established that the effect of water deficit in the critical phase of ontogenesis of earing-flowering caused decreasing of leaf surface area, mass of shoots and grains more significantly in the Perlyna Podillia cultivar compared to the Bogdana cultivar. Restoration of irrigation stimulated the growth of shoots and grains, but did not compensate for the loss of their number. Conclusions. Water deficit in soil in critical earing-flowering phase delayed the increasing mass of shoots, grains and the area of leaves that caused the decrease in plant productivity.

Published: September 2023

Aim. The aim of the study was to analyze the diversity and frequencies of alleles at the minor gliadin locus Gli-A3 in groups of common winter wheat cultivars developed in different breeding institutions of Ukraine in different periods of time. Methods. Acid polyacrylamide gel electrophoresis of gliadins was carried out. To identify the Gli-A3 allele of the cultivar Myronivska storichna, segregation in a sample of F2 seeds from crossing with the cultivar Bezosta 1 was analyzed. Results. Alleles at Gli-A3 were identified in 511 Ukrainian cultivars. In addition to the alleles a-d, a new allele Gli-A3e encoding two omega-gliadins was identified in Myronivska storichna. The alleles a and b predominate in the total group of cultivars. Differences in the allele composition and frequencies were revealed between some groups of cultivars. A significant reduction in the frequency of Gli-A3b was detected for the groups of the Plant Breeding and Genetics Institute (PBGI) and the V. Ya. Yuryev Plant Production Institute (IPP) cultivars released after 2010. Conclusions. The frequencies of the predominant alleles a and b are similar in the groups of the Central Forest-Steppe cultivars in different periods of breeding. An increase in the frequency of the allele a was noted for the groups of PBGI (the Steppe) and IPP (the Eastern Forest-Steppe) cultivars, which may indicate its adaptive value under conditions of an increase in the average annual temperature in these zones.

Authors: Laiko I. M. , Mishchenko S. V. , Kyrychenko H. I.
Published: September 2023

Aim. To study the biological features of populations of hemp varieties with the absence of narcotic activity – tetrahydrocannabinol (THC) not higher than 0.08 %, but with the presence of non-psychoactive components of cannabinoids: cannabidiol (CBD) and cannabichromene (CBC); cannabigerol (CBG); CBG and CBD. To identify breeding prospects for increasing the content of cannabinoids that have therapeutic properties. Methods. Samples of elite plants were analyzed for cannabinoid content by gas-liquid chromatography (GC Agilent Technologies HP 6890, Series Hewlett Packard). Results. The limits of variation of the population variability of the sign of CBD content of the Medana variety are from 0.0253 to 3.3469 %, 75 % of the plants of which contain CBD in the range of 1.0-2.2 %. Studies of the Vik 2020 hybrid population confirmed a high correlation between CBD and THC and the absence of a relationship between CBD and CBG, THC and CBG. More than 11 % of plants in the population contain CBG from 3.5849 to 4.6207 %. There are no correlations between CBD and CBG, CBD and THC in these plants. The presence of such plants indicates the possibility of further increasing the content of СBG to 8 % and above, without exceeding the THC limit in our country (0.08 %). Conclusions. Conducted research has proven that with the current permissible level of THC, the content of CBD can be increased only to 2.5-3.0 % (Medana variety) through purposeful selection. The hybrid Vik 2020 is especially valuable, because in its population unique plants with the presence of several cannabinoid compounds with a THC content of no more than 0.08 % were found. The obtained valuable breeding material of the Medana variety and the Vik 2020 hybrid is a donor for its inclusion in hybridization and further multi-vector selection in the direction of increasing of the content of CBD, CBC and CBG with the absence of THC.

Authors: Mazura M. Yu.
Published: September 2023

Aim. To determine the consequences of the impact of automobile emissions on the environment of the city of Kyiv using the palynological method. Methods. The quality of Taraxacum officinalis (L.) Weber ex F. H. Wigg pollen was determined by the iodine method (Gram staining). All pollen grains without typical signs of morphological structure (that is, all but normally developed) were considered teratomorphic. Results. The effect of aerogenous load on the viability of Taraxacum officinalis plant pollen was studied at test sites of park ecosystems of the city of Kyiv with different traffic intensities and proximity to city highways. It was established that in the conditions of the metropolis under various effects of air pollution, the quality indicators of the pollen of the bioindicator remain high, within 77.79 % (test site No. 1, which is located closest to the highways, where Nox is 2.11 g/s, CH – 2,86 g/s) to 81.77 % (test site No. 2 in Mariinsky Park, which has the best environmental conditions: the mixture of nitrogen oxides is 0.41, which is almost five times less than at test site No. 1 in Peremohy Park). The largest share of teratomorphic pollen (34.98 %) was recorded in T. officinalis plants in Peremogy Park test site No. 1, the smallest (26.86 %) was found in plants growing in Mariinsky Park at test site No. 2. When analyzing the data, it was determined that a high level of inverse correlation has an indicator of the fertility of pollen grains with all investigated components of air pollution (r = from -0.57 – Pb compounds to -0.73 – soot).

Aim. To investigate the variability of alpha-amylase isoenzymes in soft wheat varieties of Ukrainian selection, created by breeding institutions located in different climatic zones (Forest Steppe and Steppe). Methods. Isoenzymes of alpha-amylase were detected by electrophoretic protein separation in a polyacrylamide gel. The fall number on the «Falling Number 1700» was determined. Results. For a representative assessment of the distribution of alpha-amylase isoenzymes, we studied the zoned varieties of common wheat from two breeding centers located in different climatic zones: the Institute of Plant Physiology and Genetics of the National Academy of Sciences of Ukraine, Kyiv (Forest-steppe) and the Breeding and Genetics Institute of the National Academy of Sciences, Odessa (Steppe). The variability of wheat grain alpha-amylase was revealed. A search for associations between alpha-amylase variants and resistance to pre-harvest grain germination was conducted. Conclusions. The prevalence of alpha-amylase isoenzyme variants in Ukrainian common wheat varieties was estimated. Among Odessa varieties, the AbCd alpha-amylase variant predominates with a frequency of 50.0 %. AbCd and AbCD phenotypes with a frequency of 38.8 % predominate in the selection varieties of the IFRG of the National Academy of Sciences of Ukraine. It was shown that the genotypes containing the AbCD and ABсD isoenzyme variant are more resistant to pre-harvest germination, and the ABCd and AbcD variants are less resistant to pre-harvest grain germination.

Aim. The effect of sodium chloride on the physiological and biochemical parameters of wheat and maize genotypes, the identification of salinity-resistant varieties was studied. Wheat and maize plants were grown in pots in the soil with the addition of 0.5 % sodium chloride. To create new salt-tolerant varieties of wheat and maize, a comparative analysis of the morphophysiological parameters plants was carried out. Methods. Morphophysiological parameters such as growth, chlorophyll and carotenoid content, photochemical activty of chloroplasts and PSII activity have been studied in wheat and maize plant. Results. The effect of salt on the amount of chlorophyll a, chlorophyll b, and carotenoids, which are the main physiological indicators, is manifested in different ways in both plants. When studying salt-tolerance of plants, differences were detected in the relative amounts of chlorophyll (a+b), carotenoids, as well as the photochemical activity of chloroplasts and efficiency of PS 2. Conclusions. Among the varieties, according to all morphophysiological parameters, the most tolerant to the action of salt was the soft wheat variety Mirbashir-128, and the corn hybrid Belaya x Gurur.

Aim. Fertility disorders are one of the most common problems of reproductive medicine. Chromosomal abnormalities play a crucial role in reproductive failure. The main purpose of our study was to determine the types and frequency of chromosomal aberrations in couples with history of infertility. Methods. Karyotyping was performed in 652 couples with reproductive failure between 2004 and 2022, including 203 couples with primary infertility (PI), 240 couples with recurrent pregnancy loss (RPL) and 209 – with sporadic pregnancy loss (SPL). Results. Numerical and structural karyotype abnormalities were detected in 37 (2.84 %) of 1304 individuals with infertility, most frequently in group with PI – 3.4 % and RPL – 3.3 %. Chromosomal abnormalities were detected in 3.1 % woman and 2.6 % men. The most common cytogenetic abnormalities (26 cases of 37; 2 %) are translocations, reciprocal – 18 cases (1.4 %) and Robertsonian – 8 cases (0.6 %). Numerical and structural gonosomal abnormalities were detected in 9 individuals (0.7 %), supernumerary marker chromosome – in 2 (0.14 %). Conclusions. Karyotype abnormalities are most common in individuals with PI and RPL and a occur with the same frequency among women and men. Numerical gonosomal abnormalities were detected only as mosaic form.

Aim. The present study aimed to assess the distribution of inherited risk factors of thrombophilia among women with RPL. To determine the frequency and distribution of alleles and genotypes of polymorphic loci PAI-1 6754G/5G and ACE I/D among women with RPL. Methods. The study was carried out in a group of 97 women (57 controls and 40 women with RPL). Polymerase chain reaction and restriction fragment length polymorphism (RFLP) were used to identify the polymorphisms. Results. The frequency of 4G allele of PAI-1 675 5G/4G locus was more frequent in the group of women with RPL – 67 %, compared to 54 % in the control group. It was established that the presence of the 4G allele increases the risk of RPL by almost 2 times (Р = 0.01). In the group of women with RPL the frequency of carriers of DD genotype and D allele of ACE gene was higher than in the control group (31 % vs. 19 %), but no significant differences were found. The frequency of women with a combination of 4G4G and DD genotypes of the two studied loci was 16.6 % in the group with RPL versus 2.3 % in the control group. It was shown that the presence of homozygotes for two alleles 4G of the PAI-1 gene and D of the ACE gene leads to an 8-fold increased risk of RPL (OR = 8.6, CI: 0.9841-75.154, P = 0.04). Conclusions. Significance of PAI-1 675 4G/5G and ACE I/D polymorphic variants, especially in combination, in the predisposition to RPL was established.

Aim. Study of the influence of selective light irradiation on the content of soluble carbohydrates and proteins in the axial organs of seedlings of soybean varieties with a contrasting photoperiodic response (PPR). Methods. As plant material we used etiolated seedlings of soybean (Glycine max (L.) Merr.) SDP Khadjibei variety and DNP Yatran variety. Etiolated seedlings were irradiated daily for 30 minutes (5 days) using LED matrices with red, green and blue light. Then the material was fixed and a biochemical analysis was carried out in the axial organs of the seedlings – the content of soluble carbohydrates and proteins was determined. Results. GL and BL irradiation had the maximum effect on the content of soluble carbohydrates in SDP soybean seedlings of Khadjibey variety. In soybean seedlings of the DNP Yatran variety a significant effect was exerted by the action of all studied spectra, which was manifested in a decrease in their content in the above-ground part and growth in the root system. The content of proteins in seedlings of both varieties under the influence of selective light increased in both parts of the seedling. The most significant effect was observed for the irradiation of GL. Conclusions. The effects of selective light irradiation are manifested differently in shoots and roots, which may be due to the different composition or activity of the photoreceptor systems of the axial organs.

Published: September 2023

Aim. Production of genetically modified plants of new promising winter wheat genotypes with partial suppression of the proline dehydrogenase gene in in vitro culture and determination of proline content in transgenic and control plants. Methods. Agrobacterium-mediated transformation in culture in vitro, molecular genetic analysis; biochemical determination of proline content; of mathematical statistics. Results. Using the method of Agrobacterium-mediated transformation of callus cultures of new promising genotypes of winter wheat, transgenic plants carrying a double-stranded RNA suppressor of the proline dehydrogenase gene were obtained. The frequency of transformation with the use of the LBA 4404 strain in the studied genotypes was 1.7-2.0 %, and with the use of the AGL0 strain, it was 2.0-2.3 %. It was established that plants with reduced activity of proline dehydrogenase are characterized by a significantly higher content of free L-proline compared to the control. Conclusions. The relatively greater efficiency of using the AGL0 strain for obtaining transgenic plants of winter wheat genotypes with partial suppression of the proline dehydrogenase gene in in vitro culture is shown. The presence of a double-stranded RNA suppressor of the ProDH gene in transgenic plants leads to an increase in the level of free L-proline accumulation.
