Improving the grain quality of modern spring bread wheat cultivars is a highly relevant task of breeding. To solve this problem, old and local wheat varieties (landraces) are of considerable interest. A rich collection of them is available among the plant genetic resources preserved at VIR. With this in view, the aim of this research was to identify sources of high protein, gluten, macro- and micronutrient content out of the landraces from the VIR collection for improvement of wheat grain quality through breeding.Materials and methods. Field and laboratory research were conducted in the experimental field of Omsk State Agrarian University under the conditions of the southern forest-steppe of Western Siberia in 2020–2021. Sowing was carried out on fallow on conventional sowing dates. Mineral composition in the grain of the studied landraces was analyzed at the Kurchatov Genomic Center, Novosibirsk, using atomic absorption spectrometry techniques.Results. The research results showed that landraces from different regions of Russia, Kazakhstan, Tajikistan, and Kyrgyzstan were characterized by high levels of protein (18.4–18.8%) and gluten (35.9–36.0%) in grain. Landraces from Kazakhstan had low Zn content (on average 38.3 mg/kg), while those from Kyrgyzstan, on the contrary, had high content of Zn (41.9 mg/kg) and Fe (55.1 mg/kg), and landraces from Tajikistan had high K content (3820 mg/kg). A positive relationship between the concentrations of Mg, Mn, Fe, and Zn was found in the grain of wheat landraces.Conclusion. Wheat landraces are of interest as genetic resources for the development of high-protein cultivars with improved nutritional value of grain for the milling and breadmaking industries.","PeriodicalId":36512,"journal":{"name":"Proceedings on Applied Botany, Genetics and Breeding","volume":" 25","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139628250","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}

PSTVd is a circular, single-stranded RNA molecule that does not code for proteins. Symptoms caused by PSTVd lead to a significant reduction in tuber yield or death of the plant. PSTVd infection triggers the silencing of host-plant genes and induces disease symptoms in the plant via vd-sRNA. The StTCP23 potato gene which encodes a transcription factor is one of the targets of PSTVd. The aim of the study was to assess the effect of inoculation of potato plants of cv. ‘Colomba’ with the PSTVd viroid NicTr-3 strain on the StTCP23 expression in infected plants. Materials and methods. Potato plants of cv. ‘Colomba’ were inoculated with leaf sap of the tomato cv. ‘Rutgers’ in which the PSTVd viroid NicTr-3 strain was propagated. RT-PCR with specific primers was used to confirm the infection of potato plants with the viroid. Diversity of RNA molecules in the PSTVd population was revealed using RT, cloning, and sequencing of the viroid. The expression of the StTCP23 gene in infected potato plants was assessed by quantitative PCR with the ef1 α gene as a reference. Results. Symptoms of infecting ‘Colomba’ plants with the PSTVd viroid strain NicTr-3 were not detected, while the presence of the viroid in potato leaves was confirmed by molecular methods. Ten mutations were found in individual variants of the PSTVd strain NicTr-3, responsible for reducing the viroid’s aggressiveness. An increase in the expression of StTCP23 was shown at 3 time points in ‘Colomba’ plants inoculated with the NicTr-3 strain compared to the control. Conclusion. The mechanism of interaction between PSTVd and the StTCP23 gene in an infected potato plant is not universal and depends both on the potato genotype and viroid strain. Additional studies are required to prove the existence of specific interaction mechanisms between the host-plant and viroid strain genotypes.","PeriodicalId":36512,"journal":{"name":"Proceedings on Applied Botany, Genetics and Breeding","volume":"42 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135413973","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 qualitative composition of wheat grain varies depending on the cultivar, soil and climate conditions, and agricultural practices. The allelic composition of glutenins in bread wheat cultivars is an important parameter for the analysis and management of their genetic structure. In this respect, there is an interest in studying the genetic diversity of alleles of high-molecular-weight glutenin subunits (HMW-GS) in bread wheat cultivars from Europe, Asia, Africa, and America. Materials and methods. The total diversity of alleles in Glu-1 glutenin loci was evaluated according to the calculation of the Nei index (H). Using this indicator and the cluster analysis, wheat cultivars of various ecogeographic origin were distributed into relatively homogeneous groups. Results. Wheat cultivars from Poland, Germany, France, Spain, Portugal, Turkey, Iran, Pakistan, India, China, and Algeria (Group I) had the average Nei index of 0.59, and those from the U.S., Mexico, Argentina, Russia, Kazakhstan, Ethiopia, Czech Republic, Hungary, Bulgaria, Afghanistan, and North Korea (Group II) had 0.42. These groups of wheat cultivars differed in the frequency of occurrence of glutenin subunits at each Glu-1 locus: N, 7+9, 2+12 in Group I, and 2*, 7+9, 5+10 in Group II. Conclusion. Wheat cultivars from Group II had on average a low level of variability of allelic genes in the respective loci, manifesting high grain quality of these cultivars and the highest probability of their genetic depletion compared to the cultivars from Group I, where most of the cultivars are described by a combination of low-quality glutenin subunits.","PeriodicalId":36512,"journal":{"name":"Proceedings on Applied Botany, Genetics and Breeding","volume":"49 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135414145","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}

Cornus mas L. is grown in Europe, Central Asia, and the Middle East. Natural thickets are widespread in the Caucasus. The aim of this work was to analyze ecological and biological features of C. mas and the results of its introduction in order to justify the potential of its valuable agronomic traits for breeding and landscaping in Orel Province. Methods and materials. Specimens of C. mas preserved in the arboretum of the Russian Research Institute of Fruit Crop Breeding since 1968 were analyzed. The studies were conducted from 2012 through 2021. Winter hardiness, plant condition, degrees of flowering and fruiting were assessed using conventional techniques, while the degree of ornamentality was determined according to O. Yu. Emelyanova’s method. Results and conclusion. Under the conditions of the arboretum, C. mas is a multi-stemmed shrub, up to 5.3 m high, with an average crown projection diameter of up to 4.7 m, showing good vitality, active growth, and a high degree of resistance to damaging climatic factors of the winter season. No damage by diseases or pests was observed during the studies. The sum of effective temperatures for the beginning of C. mas flowering was 46.6 ± 2.0°C. Flowering started on April 15 (± 7 days). On average, flowering lasted 17 ± 5 days in the arboretum. Annually, the degree of flowering was high (4.8–5.0 points), and the vigor of fruiting was good (3.8–4.1 points). Peaks of C. mas ornamentality were observed in April, during the early abundant flowering of plants, and in August, during the ripening of fruits. The ornamental period of C. mas was on average 208 (± 12) days. The analysis of ecological and biological features of C. mas under the conditions of Orel Province showed the prospects of this species’ introduction. Formation and study of C. mas collection from neighboring regions will serve as a basis for successful breeding to obtain new cultivars with valuable traits for the conditions of Central Russia.","PeriodicalId":36512,"journal":{"name":"Proceedings on Applied Botany, Genetics and Breeding","volume":"42 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135414150","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}

Cultivation of scab-resistant apple cultivars with better fruit storability increases the economic efficiency and environmental friendliness of horticulture. Hence, the development of such cultivars is an important task in modern apple-tree breeding. Materials and methods. A set of 646 hybrid plants obtained in six cross combinations (Renet Simirenko/Modi, Renet Simirenko/Smeralda, Renet Simirenko/Renoir, Renet Simirenko/Fujion, Renoir/Granny Smith, and Modi/Granny Smith) was studied. Their scab resistance was assessed under natural infection pressure for two years using a quantitative scale. The Rvi6 gene was identified using the PCR analysis with the primer pair VfC1+VfC. The Md-ACS1 gene alleles were detected with a known SCAR DNA marker. The chi-square test was applied for statistical confirmation of the data. Results. Based on the DNA marker analysis, 328 plants carrying the dominant allele of the Rvi6 gene were identified. The results of the phenotypic resistance assessment confirmed the correspondence of the resistant phenotype / dominant allele of the gene for most plants. Molecular genetics analysis of the Md-ACS1 gene disclosed its allelic combinations. A total of 190, 322, and 126 plants carrying allelic variants of Md-ACS1-2/2 , Md-ACS1-1/2 , and Md-ACS1-1/1 , respectively, were identified. Among the plants with the dominant allele of the scab resistance Rvi6 gene, 92 plant forms were identified with Md-ACS1 -2/2, and 143 heterozygous ones ( Md-ACS1-1/2 ), also valuable for breeders. Conclusion. A wide range of apple breeding forms carrying valuable alleles of the Rvi6 and Md-ACS1 genes were selected. Hybrid forms with target alleles of both genes responsible for important agronomic traits would contribute to the intensification of breeding efforts aimed at producing scab-resistant apple cultivars with increased fruit storability.
