Ohba in the conditions of Kryvorizhzhia during 2003–2021 years. In the conditions of the steppe zone of Ukraine, global climate changes are associated with rising temperatures and prolonged droughts, especially during the period of active vegetation of plants. This leads to the creation of stressful conditions for the vital activity of plants used in landscaping. In this regard, plants change the rhythms of growth and development, adapting to the climatic conditions of the area of growth. The limiting factors are mainly air temperature and daily photoperiod. The purpose of the work is to determine the phenology features of individual species of the genera Sedum and Hylotelephium at introduction into the Kryvyi Rih Botanical Garden of the National Academy of Sciences of Ukraine under the influence of climate change. The objects of the study were Sedum aizoon L., S. album L., S. florіferum Praeg., S. hybridum L., S. reflexum L., S. spurium M. Bieb., S. takesimense Nakai, Hylotelephiuт ewersii (Ledeb.) H. Ohba, H. spectabile (Boreau) H. Ohba. The increase in annual air temperature caused changes in the timing and duration of certain phases of development of the vegetative and generative spheres. Accordingly, there was an increase in the growing season by 20–50 days. When introduced to the Kryvyi Rih Botanical Garden of the National Academy of Sciences of Ukraine, S. floriferum, S. takesimense and S. spurium change their phenotype from winter-green to spring-summer-autumn-green. It has been observed that S. album, S. reflexum, S. spurium, S. floriferum, S. hybridum and S. takesimense, which flower in July in their natural habitats, begin bloom in June аn Kryvorizhzhia, and in 2017–2021 the timing is accelerated – it is already the end of May–beginning of June. The difference in time reached 12–18 days. The average duration of flowering sedums was 22–30 days. During 2003–2021, the duration of flowering increased reliably in S. aizoon, S. floriferum and S. reflexum. In the conditions of Kryvorizhzhia, the species S. floriferum, S. takesimense and S. spurium change their development strategy – they do not vegetate in the winter period and bloom in June, which is not typical for them in the conditions of natural habitats. There is also a change in the flowering period to the early-summer period in S. album, S. reflexum and S. hybridum, which are summer-flowering. The identified features of the seasonal rhythm of development indicate a significant level of plasticity of the studied species.","PeriodicalId":173296,"journal":{"name":"NaUKMA Research Papers.

The tract is located in the city of Kyiv, directly adjacent to a large residential area and two highways. An analysis of the main factors affecting the ecological state of the territory was conducted. Among the main factors negatively impacting the state of the ecosystem of the Teremky Tract, the following can be distinguished: vandalism, which includes setting fire to old trees and causing various types of damage to them; plucking of flowering plants; environmental pollution with solid household waste; direct and indirect influence of hazardous objects such as boiler plants and gas stations; and the influence of transport infrastructure. The article demonstrates the need for constant monitoring of the ecological state of natural biotopes located within modern megacities. It is shown that the monitoring of floristic diversity, controlling the preservation of valuable and rare plant species, and tracking the appearance and spread of invasive alien species can be effective indicators of the ecological state of the natural biotope. Thus, populations of forest lily (Lilium martagon L.) and cuckoo’s tears (Listera ovata L.) were found on the territory of the Teremky Tract, which are included in the Red Book of Ukraine. Additionally, a group of 400-year-old oak trees grows in this area. However, the presence of invasive alien species such as red oak (Quercus rubra L.), the ash-leaved maple (Acer negundo L.), black cherry (Prunus serotina L.) and Robinia pseudoacacia L. was also observed. Monitoring of floristic diversity in natural biotope areas within megacities plays an important role in timely response to the effects of negative natural and anthropogenic factors for the preservation of the environment of these urban ecosystems. Such monitoring can be conducted both through field observations and using remote methods and analysis of global biodiversity databases such as iNaturalist and GBIF.","PeriodicalId":173296,"journal":{"name":"NaUKMA Research Papers.

Based on literature, herbarium, inventory and other information, it was established for the first time that 3 native taxa (outside natural ranges) and 16 alien taxa of the genus Corydalis were recorded among ergasiophytes in botanical gardens and dendrological parks of Ukraine. The majority of these ergasiophytes (73.7 %) have not been preserved in the collections of living plants, indicating a low level of naturalization. The leading scientific center for the plant cultivation, where 82.4 % of alien taxa of the genus Corydalis have been cultivated, is the M. M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine (Kyiv). Additionally, 4 alien taxa at different stages of naturalization were noted in the spontaneous flora of Ukraine. These include the ephemerophyte C. bracteata, colonophyte C. lutea, epecophyte C. cava subsp. marschalliana (outside the natural range) and hemiagryophyte C. caucasica. In the conditions of M. M. Gryshko National Botanical Garden and Syretsky Dendrological Park (Kyiv) ontogenetic structure of native coenopopulations of C. solida and introduced coenopopulations of naturalized alien taxa C. cava subsp. marschalliana and C. caucasica have been found. It was found that the coenopopulations of C. solida belong to the mature or aging types; C. cava subsp. marshalliana – to the young type; C. caucasica – young with a bias towards an invasive type. The highest density and a high seed germination in various coenotic conditions, which emphasizes the invasive nature of this species, distinguish coenopopulations of C. caucasica. Its expansion in the conditions of the M. M. Gryshko National Botanical Garden corresponds to the existing trend of the invasive spread of alien species from the southern regions, which is intensified by Global Climate Change. Due to the invasive activity of C. caucasica, this alien taxon, according to existing recommendations, should be considered as an invasive plant at the initial stage of expansion, so it should not be recommended for introduction to other countries and should be prevented from spreading in Ukraine.","PeriodicalId":173296,"journal":{"name":"NaUKMA Research Papers.

Eleven tall bearded iris varieties of domestic and foreign selection were chosen from the collection fund of the M. M. Gryshko National Botanical Garden. The varieties selected are: ‘Alians’, ‘Amethyst Flame’, ‘Earth Song’, ‘Local Color’, ‘Mescalero Chief’, ‘Scintilation’, ‘Vanity’, ‘Violet Harmony’, ‘Zlatokudraya’, ‘Ayu-Dag’, and ‘Pryvit Z Ukrayiny’. These varieties are distinguished by their decorative qualities, are widely distributed and are promising candidates for further selection work. Among the researched varieties, fruit bodies of obovate, wide-oval, elongated-elliptic and rounded shapes were distinguished. Seeds of compressedprismatic, rounded, wedge-shaped, inverted ovoid and flattened-semicircular shapes were recorded. The surface of the seeds observed was spongy-wrinkled, hard, sometimes with narrow rims along the edge of the faces. The shape of the hilum showed slight variations. The described carpological features of the I. hybrida varieties align with literature data on the general morphology of the fruits and seeds of other types of irises. The varieties of I. hybrida studied were from the M. M. Gryshko National Botanical Garden collection fund, and when grown in the conditions of the forest-steppe, we’re able to form full viable seeds with free pollination, which indicates their high adaptability. According to the histogenetic classification, the fruits of the studied varieties belong to the Lilium type (with a lignified endocarp). The structure of the seed coat, consisting of the exo-, meso- and endotesta, differences in the size, shape of the seeds and the hilum were also noted.

Changes in gene expression due to such modifications can be inherited in generations and contribute to the selection of resistant plants in populations.The nuclear pore complex is composed of nucleoporins, a nuclear pore basket, cytoplasmic filaments and is able to selectively transport transcription factors to the nucleus from the cytoplasm and mRNA in the opposite direction, affecting gene expression. Methylation is the most common and well-studied among the epigenetic modifications. It is described for DNA and histones and ensures genome stability and the availability of transcription factors. Incorporation of methyl groups to amino acid residues is not always a factor in gene silencing for histones. The number of the incorporated groups as well as an amino acid they are attached to are crucial. Histone acetylation is associated with the transition to transcriptional activity.The general control histone acetyltransferase TaGCN5 is able to promote expression of the enoyl-CoA reductase gene in allohexaploid wheat, which is involved in the biosynthesis of cuticular wax as one of the resistance factors. The reverse process of deacetylation acts both as a positive regulator, through ethylene response factors, and a negative one, as it interferes with acetylation and methylation of histone amino acids. Jasmonic and salicylic acids, along with combinations of the mentioned phytohormones, mediate formation of systemic acquired resistance in addition to ethylene. Auxin is a positive phytohormone for pathogens due to its ability to influence the structure of the cell wall. At the same time, pathogens, due to effectors, are able to inhibit the plant’s immune responses, so there is a constant “arms race” resulting in the selection of more effective means of penetration and development in the plant as well as its protective reactions. Investigation of the mechanisms of resistance formation and identifying the main factors of resistance, such as either presence of a gene sequence and/or factors regulating its expression, are of great importance.","PeriodicalId":173296,"journal":{"name":"NaUKMA Research Papers.

In 2019–2020, under the conditions of the subpopulation of the pathogen, typical for the Right Bank Forest-Steppe zone of Ukraine, the effectiveness of known resistance genes was determined. Evaluation was conducted after the 2018 epiphytotypic series on a series of nearly isogenic Thatcher wheat lines and cultivars that expand the core gene set. According to the research results, they are distributed into several groups according to the level of expression: 1) genes capable of determining a very high level of resistance to all local races of the pathogen (score 9 – no signs of the disease; score 8 – single necrotic spots) Lr9, Lr18, Lr19, Lr21, Lr25, Lr27+31, Lr28, Lr35, Lr41, Lr43+24, Lr50, LrTm; 2) genes determining resistance – plants are slightly affected by the pathogen (score 8 – single necrotic spots and urediniopustules with an intensity of up to 5 %; score 7 – urediniopustules with an intensity of up to 10 %; score 6 – small and medium urediniopustules with an intensity of up to 15 %) – Lr22a, Lr32, Lr34, Lr42, Lr43, Lr46; 3) resistance genes whose expression level is defined as labile (heterogeneous) – Lr2a, Lr2b, Lr12, Lr14a, Lr14b, Lr20, Lr23, Lr24, Lr39, Lr40.

More than 1 billion people worldwide are obese, and this number is growing. Obesity at an early age is accompanied by impaired carbohydrate tolerance and the development of type 2 diabetes, lipid metabolism pathology, obstructive apnea, hypercoagulability, chronic inflammation and the development of insulin resistance in the future. In modern literature, there is no single point of view regarding the role of the autonomic nervous system in the coordination of hormonal, nervous and metabolic factors in the body.Aim. The article presents the results of studying the functional state of the sympathetic and parasympathetic parts of the autonomic nervous system in overweight persons and presents an assessment of the central hemodynamic parameter depending on the type of autonomic reactivity of the cardiovascular system.Methods. The study involved measuring systolic and diastolic blood pressure, heart rate, and anthropometric measurements for calculating the corresponding indices. An active orthostatic test to determine the functional state of reflex mechanisms for regulating hemodynamics. Statistical methods were used for data analysis.Results. Based on anthropometric indicators and calculated indices, boys and girls with overweight differed from the control group in abdominal and total distribution of fat. However, there were no differences in terms of vegetative tone (sympathicotonic, vagotonic, eutonic). The distribution of eutonic and vagotonic types of the autonomic nervous system and sympathicotonia was similar in both groups. Most overweight individuals had insufficient reactivity of the parasympathetic autonomic nervous system. Paradoxical reactivity in both groups was observed with the same frequency. In the group of people with paradoxical autonomic reactivity among overweight people, a significantly lower increase in heart rate was found than in the control group. In persons with overweight and increased autonomic reactivity, minute blood volume and pulse pressure increased 1.5-fold, there was a tendency to increase stroke volume and inotropic function of the heart. The increase in this characteristic indicated a hyperkinetic type of hemodynamics in overweight persons in the group with normal autonomic reactivity. In groups with paradoxical and increased autonomic reactivity of the cardiovascular system, a normokinetic type of hemodynamics was observed.Conclusions. Signs of altered autonomic reactivity found in most overweight individuals indicate dysfunction of the parasympathetic autonomic nervous system and possible dysfunction of nonspecific regulatory (limbic-reticular) parts of the brain.","PeriodicalId":173296,"journal":{"name":"NaUKMA Research Papers.

Transfer of resistance genes from wild relatives into the wheat genetic pool could be an alternative to the use of fungicides. This review contains classification of powdery mildew resistance on different ontogenetic stages (seedling resistance and adult resistance), expression of the trait (quantitative and qualitative), and genes conferring resistance (wide-spectrum and race-specific resistance). Powdery mildew resistance genes are characterised; the number of identified resistance genes is constantly increasing, and in 2019 the number of genes / alleles was 89. The genes controlling the desired trait have originated from different wheat relatives, namely: rye (Secale cereale L.), Dasypyrum villosum (L.) P. Candargy (Haynaldia villosa Schur), Thinopyrum intermedium, and species from the genera Aegilops and Triticum. Resistance genes are classified by their products, chromosome localization, and presence of different alleles. For a number of genes, chromosome localization and the nature of protein products have not yet been determined. Attention is also focused on possible complications that could arise during the identification of new genes, when already known resistance genes / alleles could be falsely identified as new ones. Resistance genes protein products are mostly receptors, which are classified according to their domain structure. The most variable domains in these proteins are leucine-rich repeats (LRRs), which provide the specificity of the receptors. Interaction between pathogen effectors and plant resistance proteins occurs through direct physical interaction or through the intermediate signalling events. Resistance genes and their products have been described, based on the results of the experiments conducted on wheat and other model plants, including monocots (rice), although the information obtained on Arabidopsis thaliana has also been analyzed.","PeriodicalId":173296,"journal":{"name":"NaUKMA Research Papers.

The obtained new data made it possible to determine the ecological state of the meadow-steppe landscape, as well as the possible use of disturbed lands bordering the buffer zone. The necessity of introducing a protective zone of the National Nature Park has been proven. This will allow to timely assess the ecological state of landscapes; to prevent negative consequences for the protected areas, and in the future to include them in the composition of the protected territory. The conducted studies of floristic diversity and monitoring of disturbed lands in the southern border zones of the Nyzhnosulskyi National Park made it possible to state that there are threats of salinization, impoverishment of floristic diversity, and soil degradation for the southern border area under conditions of increased anthropogenic load or resumption of agricultural operations. It has been established that rare and red-listed plants within the landscape complex “Ivanivski Ozera”, which are also known within the National Nature Park “Nyzhnosulskyi”, have disappeared under the influence of mechanical and chemical intervention by farmers. Some halophytes and other steppe plants with deep or branched root systems remained. Taking into account the peculiarities of the relief of the territory of the Ivanivskі Lakes, the aridization of the climate and the speed of soil salinization processes in the lower Sula within the Obolon depression and under the conditions of further ploughing of the land, the territory will turn into salt marshes. The area of soil salinization will extend to the territory of the Park, which will lead to irreversible changes in the phytocoenosis and the appearance of salt marshes and an even greater number of halophytes. Scientific monitoring of the disturbed lands of the border zone of the nature reserve confirms that for the preservation and protection of floodplain complexes of the Sula River and meadow-swamp ecosystems, it is necessary to provide systematic research and a timely forecast of ecological changes in landscapes; prevention and elimination of negative consequences for protected floristic areas. In addition, it is advisable to include the lands of the buffer zone as part of the protected area of the National Nature Park and determine the degree of effectiveness of measures aimed at the preservation and restoration of land resources.","PeriodicalId":173296,"journal":{"name":"NaUKMA Research Papers.

For the first time, 31 new taxa were introduced for the regional flora of Cherkasy region, including 8 native and 23 alien. The most valuable is the information about rare aboriginal plants, in particular Asparagus tenuifolius, Euphorbia salicifolia, Polygonum patulum, Rosa andegavensis, etc. In the Uman district of Cherkasy region, the location of three species of flora that were considered disappeared in the region: Pentanema oculus-christi, Salvia dumetorum and Staphylea pinnata. For once, 3 new alien species have been introduced for the flora of Poltava region: Anthriscus caucalis, Lonicera × notha and L. ruprechtiana. The research revealed new locations of invasively active foreign plants, including ergasiophygophytes: Phytolacca acinosa, Silphium perfoliatum, Vitis riparia, Zizania latifolia etc., and quarantine xenophytes: Cenchrus longispinus and Eriochloa villosa. Progressive distribution of xenophytes with primary sub-Mediterranean and Central Asian habitats has been noted.
