Purpose. Provide bioinformatic analysis and comparison of target regions of the acetolactate synthase (als) gene in several members of the Poaceae family and, on the basis of the obtained data, explore the possibility of creating a unified genetic construct for als gene editing using the CRISPR-Cas9 system. Methods. The als gene sequences of various members of the Poaceae family were obtained from the NCBI: Nucleotide database. For comparison, a fragment of the imi-2 gene of wheat of the soft line ‘TealIMI11A’ was used in two regions of the 367–390 and 1729–1749 nucleotide sequences. The Sequence Viewer 3.37.0 tool was used to assess the presence of nucleotide substitutions in the working sequence of the imi-2 gene. The dendrogram was built using the “Blast Tree” tool from the NCBI: Blast: Nucleotide resource. Results. A comparative analysis of the nucleotide sequences of seven different species was carried out: soft wheat (Triticum aestivum L.), common wild oat (Avena fatua L.), barley (Hordeum vulgare L.), Asian rice (Oryza sativa L.), maize (Zea mays L.), aleppo grass (Sorghum halepense Pers.) and Tausch’s goatgrass (Aegilops tauschii Coss.). The dendrogram is based on the gene sequence als, showed that all studied genotypes can be divided into two blocks: the first block included maize and aleppo grass, and the second block, a separate branch includes Asian rice and common wild oat, barley, soft wheat and Tausch’s goatgrass. 367–390 nucleotide sequences of soft wheat showed the highest 100% homology to Asian rice, Tausch’s goatgrass and common wild oat. The lowest homology was for maize and aleppo grass at 83.3%. Evaluation of the nucleotide sequence 1729–1749 showed no complete homology at the 100% level. It was the highest for barley and Tausch’s goatgrass – 95.2%, and the lowest for rice, maize and aleppo grass – 80.9% each. Conclusions. The analysis confirms a significant degree of homology of the als gene sequence for various species of the Poaceae family, which allows us to create a universal genetic vector. However, taking into account the high degree of sequence homology for species such as soft wheat, Tausch’s goatgrass, barley, Asian rice and common wild oat, it can be assumed that the corresponding genetic vector can be used with the greatest efficiency to alter the als gene of these genotypes.

Провести биоинформатический анализ и сравнить целевые участки гена ацетолактат синтазы (als) у нескольких представителей семейства Злаковых и на основе полученных данных исследовать возможность создания унифицированной генетической конструкции для направленного изменения гена als с помощью системы CRISPR-Cas9.Методы. Сиквенсы гена als различных представителей семейства Злаковых были получены из базы данных NCBI: Nucleotide. Для сравнения был использован фрагмент гена imi-2 пшеницы мягкой линии ‘TealIMI11A’ в двух участках сиквенса 367–390 и 1729–1749 нуклеотидов. Для оценки наличия нуклеотидных замен в рабочих сиквенсах гена imi-2 использовали инструмент ‘Sequence Viewer 3.37.0’. Дендрограмму строили с использованием инструмента “Blast Tree” с ресурса NCBI: Blast: Nucleotide. Результаты. Был проведен сравнительный анализ нуклеотидных последовательностей семи различных видов: пшеницы мягкой (Triticum aestivum L.), овсюга обыкновенного (Avena fatua L.), ячменя обыкновенного (Hordeum vulgare L.), риса посевного (Oryza sativa L.), кукурузы (Zea mays L.), сорго алепского (Sorghum halepense Pers.) и эгилопса Тауша (Aegilops tauschii Coss.). На основе сравнительного анализа сиквенса участков гена іmi-2 для 7-ми генотипов построили филогенетическое дерево, которое показало, что исследованные виды можно разделить на два блока. В первый блок вошли кукуруза и сорго алеппское, а ко второму блоку – рис посевной, овсюг обыкновенный, ячмень обыкновенный, пшеница мягкая и эгилопс Тауша. Определение степени гомологии между последовательностью 367–390 нуклеотида пшеницы мягкой и другими видами показала, что абсолютной была гомология с соответствующими последовательностями риса посевного, эгилопса Тауша и овсюга обыкновенного (100%). Наименьшим нуклеотидное родство оказалось для кукурузы и сорго алеппского – по 83,3%. На участке 1729–1749 нуклеотидов гена іmi-2 никакой из 6 сиквенсов не показал 100% гомологии с последовательностью пшеницы мягкой. Самой высокой она была для ячменя обыкновенного и эгилопса Тауша – 95,2%, а наименьшей для риса посевного, кукурузы и сорго алеппского – по 80,9%.Выводы. Проведенный анализ подтверждает значительную степень гомологии последовательности гена als для различных видов семейства Злаковых. Это позволяет допустить возможность создания универсальной генетической конструкции, с помощью которой можно осуществлять редактирование генома и получения растений, устойчивых к гербициду разных представителей этой семьи. Учитывая высокую степень гомологии последовательностей для таких видов как пшеница мягкая, эгилопс Тауша, ячмень обыкновенный, рис посевной и овсюг обыкновенный, можно предположить, что с наибольшей эффективностью соответствующая генетическая конструкция может быть использована для редактирования гена als именно этих генотипов. | Провести біоінформатичний аналіз та порівняти цільові ділянки гена ацетолактат синтази (als) у декількох представників родини Злакових і на основі отриманих даних дослідити можливість створення уніфікованої генетичної конструкції для направленого редагування гена als за допомогою системи CRISPR-Cas9. Методи. Сиквенси гена als різних представників родини Злакових було отримано з бази даних NCBI: Nucleotide. Для порівняння було використано фрагмент гена іmi-2 пшениці м’якої лінії ‘TealIMI11A’ у двох ділянках сиквенсу: 367–390 та 1729–1749 нуклеотидів. Для оцінювання наявності нуклеотидних замін в робочих сиквенсах гена іmi-2 використовували інструмент “SequenceViewer 3.37.0”. Дендрограму будували з використанням інструменту ‘BlastTree’ з ресурсу NCBI: Blast: Nucleotide. Результати. Було проаналізовано нуклеотидні послідовності сімох різних видів: пшениці м’якої (TriticumaestivumL.), вівсюга звичайного (AvenafatuaL.), ячменю звичайного (HordeumvulgareL.), рису посівного (OryzasativaL.), кукурудзи (ZeamaysL.), сорго алепського (SorghumhalepensePers.) та егілопса Тауша (AegilopstauschiiCoss.). На основі порівняльного аналізу сиквенсу ділянок гена іmi-2 для 7-ми генотипів було побудовано філогенетичне дерево, яке показало, що досліджені види можна поділити на два блоки. До одного з них увійшли кукурудза та сорго алепське, а до другого – рис посівний, вівсюг звичайний, ячмінь звичайний, пшениця м’яка та егілопс Тауша. Визначення ступеня гомології між послідовністю 367–390 нуклеотиду пшениці м’якої та іншими видами показало, що абсолютною була гомологія з відповідними послідовностями рису посівного, егілопса Тауша та вісюга звичайного (100%). Найменшою нуклеотидна спорідненість виявилась для кукурудзи та сорго алепського – 83,3%. У ділянці 1729–1749 нуклеотидів гена іmi-2 жоден з 6 сиквенсів не показав 100% гомології з послідовністю пшениці м’якої. Найвищою вона була до ячменю звичайного та егілопсу Тауша – 95,2%, а найменшою для рису посівного, кукурудзи та сорго алепського – по 80,9%. Висновки. Проведений аналіз підтверджує значний ступінь гомології послідовності гена als для різних видів родини Злакових. Це дозволяє зробити припущення про можливість створення універсальної генетичної конструкції, за допомогою якої можна редагувати геном та отримувати рослини, стійкі до гербіцидів різних представників цієї родини. Зважаючи на вищий ступінь гомології послідовностей для таких видів як пшениця м’яка, егілопс Тауша, ячмінь звичайний, рис посівний та вівсюг звичайний, можна припустити, що ефективнішою відповідна генетична конструкція буде для редагування гена als саме цих генотипів.

Purpose. Investigation of maize ae1 gene polymorphism by bioinformatic methods. Methods. Global and local alignment of the nucleotide and amino acid sequences, in silico translation and transcription, translates modeling, primers design, phylogenetic analysis. Results. 255 nucleotide sequences of maize аe1 gene, 500 amino acid sequences of homology translates of maize ae1 gene (SBEIIb enzyme homologs) and 100 mRNA expressed from the maize ae1 gene were analyzed to establish phylogenetic relationships. Polymorphism of maize ae1 gene different regions was investigated by bioinformatic methods. Modeling of the maize enzyme SBEIIb was performed. Conclusions. According to the results of amino acid sequences of SBEIIb enzyme homologs alignment, it was found that ae1 gene orthologs are present only in monocots, paralogs – in monocots, dicots, and other taxa, including algae and animals. Based on the results of alignment of plants mRNA from which enzyme SBEIIb is translated, maize ae1 gene orthologs and the nearest paralogs encoding starch branching enzymes with chloroplast localization were defined; this suggests a possible origin of ae1 gene due to duplication of the gene encoding the 1,4-alpha-glucan-branching enzyme 2 with chloroplast or amyloplast localization. In the maize ae1 gene structure, regions were found that include polymorphic sites not defined previously. For the polymorphic sites design primers were developed that allowed to differentiate the maize lines. It was determined that the detection of polymorphism in theory can influence the enzyme function and, as a result, change the concentration of amylopectin in maize grain.

This paper presents the results of molecular studies on testing and evaluation of multiplex test systems for the genetically modified organisms’ (GMOs) identification by PCR in real time. For the detection of genetic modifications in plants of the cabbage family (Brassicaceae) screening of major regulatory sequences is insufficient, as in genetic engineering manipulations 35S promoter – of DNA-containing cauliflower mosaic virus (CaMV) is used, which presence in the test material can lead to false positive results. In this work the feasibility of testing for the presence of viral CaMV’s DNA and analysis of screened gene sequences of interest for the usage during the analysis of rapeseed (Brassica napus L.) samples. It was established that the analysis of the presence/absence of a positive result for the CaMV 35S promoter is not giving complete answers to the absence of GMO in the sample. The appropriateness of GMO’s screening in rape seeds with NOS terminator and genes of interest.

For the detection of genetic modifications in plants of the cabbage family (Brassicaceae) screening of major regulatory sequences is insufficient, as in genetic engineering manipulations 35S promoter – of DNA-containing cauliflower mosaic virus (CaMV) is used, which presence in the test material can lead to false positive results. In this work the feasibility of testing for the presence of viral CaMV’s DNA and analysis of screened gene sequences of interest for the usage during the analysis of rapeseed (Brassica napus L.) samples. It was established that the analysis of the presence/absence of a positive result for the CaMV 35S promoter is not giving complete answers to the absence of GMO in the sample. The appropriateness of GMO’s screening in rape seeds with NOS terminator and genes of interest.

Purpose. Determine the ecological plasticity and productivity of F1 sunflower hybrids created on the basis of maternal and parental lines, selected according to an accelerated selection system of lines resistant to herbicides (imidazoline and sulfonylurea groups) and broomrape (Orobanche cumana Wallr.). Methods. Statistical analysis of F1 sunflower hybrids was carried out using the methods of variation statistics, regression and analysis of variance using the Microsoft Office Excel 2016 application package. Molecular biological, biotechnological and classical selection methods were used for the accelerated system of line selection. Thus, for the purpose of targeted selection of sunflower sterility fixers, we used HRG01 molecular SCAR marker to identify the gene for the restoration of pollen fertility (Rf1). To accelerate the creation of parental lines resistant to tribenuron-methyl, we used a culture of immature embryos in vitro. Results. The results of testing of F1 sunflower hybrids at Kyiv, Chernihiv, Cherkasy (Uman and Shpolianskyi districts), Khmelnytskyi, Kharkiv, Kherson and Odesa regions. The hybrids were created on the basis of selected lines, chosen according to an accelerated selection system for herbicide-resistant lines (imidazoline (IMI-hybrids) and sulfonylurea (SU-hybrids) groups) and broomrape (Orobanche cumana Wall). The standards for comparison with hybrids were: for IMI hybrids – hybrids ‘NK Neoma’ (Syngenta) and ‘ES Genesis’ (Euralis), and for SU-hybrids – ‘SY Sumiko’ (Syngenta) and ‘P64LE25’ (Pioneer). As a result, it was found that among SU-hybrids, UA 2/106 had a 3.9% higher yield when compared to the standards (‘SY Sumiko’ and ‘P64LE25’). And for IMI-hybrids it was found that hybrids UA 1/67, UA 1/66, UA 1/84 have the same yield of 2.76 t/ha as the ‘NK Neoma’ standard. IMI hybrids UA 1/92, UA 1/102 have the same yield of 2.91 t/ha as ‘ES Genesis’. Conclusions. F1 hybrids were created on the basis of the original breeding material selected due to the accelerated system of sunflower lines selection. The hybrids were analyzed according to the yield indicator. The most productive among the tested SU-hybrids was UA 2/106 hybrid, among the IMI hybrids – UA 1/67, UA 1/66, UA 1/84, UA 1/92 and UA 1/102.

Purpose. Grapevines (Vitis spp.) are affected by many viral diseases which cause serious pathological problems. GLRaV-3 is among the most widespread leafroll viruses, while Grapevine Fanleaf Virus (GFLV) is a destructive pathogen which reduces the lifespan of grapevine. Considering the impact and the spread of these diseases, our objective was to analyse the presence of these two viruses in several grapevine varieties in grapevine collection at ATTC Vlore. Data gathered from plant pathogens serve to better understand and prevent the spread of pathogens, as a mandatory rule for the quality control of certified plant material during vegetative propagation. Method. The presence of two common viruses were tested using virus specific primers; LC1/LC2 primer pair designed from the hHSP70 gene for detecting Grapevine Leafroll-associated Virus-3 (GLRaV3) and C3390/H2999 primer pair, designed from coat protein coding regions for detecting Grapevine Fanleaf Virus (GFLV), in six varieties; ‘Merlot’, ‘Kallmet’, ‘Shesh i zi’, ‘Shesh i bardhё’, ‘Debinё’, and ‘Pulёz’, provided through a randomised sampling procedure. One Step Reverse Transcription Polymerase Chain Reaction assay was used to detect the viral presence. Results showed a high (100%) prevalence of GLRaV3 virus in all of analysed samples, as the most frequent among the two pathogens. Analysis for of GFLV virus showed low infection rate, being present in only one sample. Conclusions. We herein show an efficient, fast and reproducible method for detecting grapevine viruses through one step RT-PCR. Our results suggest that sampling of the infected plant material should be avoided due to the presence of viral infections.

ABSTRACT The fungi of the order Onygenales can cause important human infections; however, their taxonomy and worldwide occurrence is still little known. We have studied and identified a representative number of clinical fungi belonging to that order from a reference laboratory in the USA. A total of 22 strains isolated from respiratory tract (40%) and human skin and nails (27.2%) showed a malbranchea-like morphology. Six genera were phenotypically and molecularly identified, i.e. Auxarthron/Malbranchea (68.2%), Arachnomyces (9.1%), Spiromastigoides (9.1%), and Currahmyces (4.5%), and two newly proposed genera (4.5% each). Based on the results of the phylogenetic study, we synonymized Auxarthron with Malbranchea, and erected two new genera: Pseudoarthropsis and Pseudomalbranchea. New species proposed are: Arachnomyces bostrychodes, A. graciliformis, Currahmyces sparsispora, Malbranchea gymnoascoides, M. multiseptata, M. stricta, Pseudoarthropsis crassispora, Pseudomalbranchea gemmata, and Spiromastigoides geomycoides, along with a new combination for Malbranchea gypsea. The echinocandins showed the highest in vitro antifungal activity against the studied isolates, followed by terbinafine and posaconazole; in contrast, amphotericin B, fluconazole, itraconazole and 5-fluorocytosine were less active or lacked in vitro activity against these fungi.
