We studied the parental varieties of spring bread wheat, accessions of the tetraploid and hexaploid Triticum L. species, and 19 introgressive lines produced with their participation. Glutenins were separated using sodium dodecyl sulfate polyacrylamide gel electrophoresis and HMW-GSs were identified using the Payne nomenclature system. Gluten quality was determined in accordance with GOST 13586.1-68 (the 2017–2019 and 2021–2022 growing seasons). Data processing was performed using the Statistica 10.0 and MS Excel software packages.Results and conclusion. HMW-GSs uncharacteristic of T. aestivum cultivars were identified in the studied accessions of T. dicoccoides (Körn. ex Aschers. et Graebn.) Schweinf., T. spelta L., and T. kiharae Dorof. et Migusch. These HMW-GSs are of interest for enriching the wheat gene pool. HMW-GSs of related species were found in 10 out of 19 introgressive lines. A five-year observation period revealed that wheat relatives on average significantly exceeded common wheat cultivars in gluten quality, and introgressive lines did not differ significantly from the parental genotypes. Lines with high rheological properties of gluten had, as a rule, HMW-GSs of related species in their composition.","PeriodicalId":36512,"journal":{"name":"Proceedings on Applied Botany, Genetics and Breeding","volume":"115 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141017559","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}

Tomato fruits are rich in vitamins, minerals, and pigments, including lycopene. The high demand and the need to enhance tomato production call for new improved cultivars and F1 hybrids.Biotechnological methods reduce the time for source material development and the labor intensity of breeding efforts. Obtaining doubled haploid plants makes it possible to fix and analyze new gene combinations faster than with conventional breeding techniques, and produce homozygous genotypes. Tomato is highly unsusceptible to haploid induction, which has been continuously studied for more than 40 years and is still of special interest. The main methods for producing haploids are based on androgenesis and gynogenesis. Androgenesis is the production of haploids from the cells of the male gametophyte, and gynogenesis from the cells of the female gametophyte.The objective was to review the research on the induction of tomato haploids based on androgenesis and gynogenesis. No standardized, efficient or reproducible protocols are currently available to produce doubled haploids of tomato. It is necessary to determine the incubation conditions, physicochemical environments, dependence of the genotype in vitro, physiological state of the donor plant, and development of the anther, which affect the reproducibility of protocols to achieve haploid induction. Anther culture for obtaining haploid tomato plants has not yielded successful results, and the studies on microspore culture were too few, so it is difficult to understand the effectiveness of this technique. The method of gynogenesis is poorly investigated, but the culture of unfertilized ovules can become a successful way to obtain tomato haploids, with more research on this subject.","PeriodicalId":36512,"journal":{"name":"Proceedings on Applied Botany, Genetics and Breeding","volume":"97 S2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141015933","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}

This review briefly characterizes the global grapevine gene pool, approaches to its conservation, including base and duplicate conservation techniques, and the current status and prospects of the progress in in vitro and cryogenic preservation methods. The genetic potential of grape wild relatives is assessed focusing on particular species as sources of resistance genes to biotic and abiotic stressors. Achievements in the application of gene editing technologies to increase grape resistance to diseases are discussed. It is noted that a common practice at this stage is to knock out the genes responsible for grapevine susceptibility to diseases, whereas a more advantageous approach in the future will be to make targeted changes in the grape genome based on the knowledge of resistance genes in its wild relatives. Therefore, grape wild relatives need to be studied thoroughly using modern methods of forward and reverse genetics. Regarding the issues of grape genetic diversity conservation and expansion at the current technological stage, the status and significance of the plant germplasm and herbarium (WIR) collections held by VIR are scrutinized in detail. Authentication of grape germplasm accessions is marked as important, along with the role of the WIR herbarium, a unique collection incorporating physical carriers of reference genetic information on the national grapevine gene pool. Promising trends in the development of the WIR herbarium are outlined in connection with the establishment and preservation of nomenclature standards for domestic grape cultivars.","PeriodicalId":36512,"journal":{"name":"Proceedings on Applied Botany, Genetics and Breeding","volume":"24 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141015727","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}

Table beet (Beta vulgaris L.) contains a great amount of naturally red-colored betanins. A number of enterprises are forced to import foreign dyes because the reserves of domestic plant raw materials are insufficient. With this in view, the development of cultivars with high betalain pigment content is now required.Materials and methods. Allelic differences were screened in the key genes of the betalain biosynthesis pathway among table beet accessions with various root color from the VIR collection using the Sanger DNA sequencing method.Results and discussion. For the first time we identified a nonsense mutation in the CYP76AD1 gene in cv. ‘Serdolik’ with yellow flesh; it led to the truncation of the functional P450 domain. We suggested that the detected polymorphism correlated with phenotypic switching because the well-known role of CYP76AD1 was essential for the red betalain accumulation. Moreover, a number of missense mutations in cv. ‘Avalanche’ in the first exon of the BvDODA1 gene were found. These mutations were probably associated with the expression of the uncolored phenotype. An in silico analysis revealed highly homologous copies of CYP76AD5, located tandemly on chromosome 9. Attention should be paid to these copies, together with the CYP76AD6 gene, as they seem the most preferable targets for a knockout to increase the red pigment content.Conclusion. It is possible to identify the best table beet accessions for further genome editing among a previously selected high-betanin group. In addition, this study revealed the allelic differences in the key genes of the betalain biosynthesis pathway. These results will be useful for the development of DNA molecular markers to facilitate the selection of table beet forms with required properties.","PeriodicalId":36512,"journal":{"name":"Proceedings on Applied Botany, Genetics and Breeding","volume":"89 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141017621","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}

Statistical processing was made in the DARwin program (version 6.0.21).Results and conclusion. Eight primers were used to amplify 116 fragments, 62 (53.4%) of which turned out to be polymorphic. To assess the effectiveness of the analyzed primers and identify the polymorphism of millet, basic indicators of their informativeness were calculated and assessed by quantifying four marker parameters. Average PIC (0.27–0.36), EMR (1.38–14.5) and MI (0.12–4.87) values were obtained for most ISSR primers. Four ISSR primers had high Rp values (3.52–6.76) and were the most informative for genotyping. The selected ISSR markers were used to assess the genetic variability of the accessions and identify them. The values of genetic distances (GD) were 0.05–0.21.

Among cereal crops, oat is second only to rye and triticale in terms of resistance to exchangeable Al forms. Despite the crop’s high environmental plasticity, an important condition for obtaining sustainable oat yields is the development of new cultivars with resistance to adverse environmental factors, including metal toxicity and high soil acidity.The objective of this work was to search for oat cultivars resistant to soil stressors (excess of Н+ and Al3+) for use in breeding for edaphic resistance.Materials and methods. The research material included 687 oat accessions from the VIR global plant genetic resources collection. The accessions underwent laboratory evaluation of their aluminum tolerance at the initial growth and development stages using the method of measuring radicle growth after the exposure to aluminum stress.

A heterotic hybrid of rice was obtained in China with a yield of 13.9 t/ha; it has a new plant morphotype (New Plant Type) and a growing season of 163 days. The hybrid is classified as “super rice”.Modern breeding programs are aimed at producing cultivars of “Green Super Rice” using pedigree methods and backcrossing for introgression of target genes through DNA markers, QTL mapping, pyramiding, and recurrent selection.Russian breeders have traditionally produced rice cultivars adapted to local conditions, with a growing season of no more than 125 days. In the 1980s, a program was launched to develop a high-yielding rice cultivar with erectoid leaves for condensed planting. As a result of multiple stepwise hybridization and targeted selection, new source material with target traits of “super rice” was released. Cv. ‘Polyus-5’ with a new plant morphotype was obtained on its basis. This cultivar was included in the State Register and from 2023 approved for commercial production. During the field trials, ‘Polyus-5’ yielded a maximum of 1380 g/m2 over 120 days of the growing season, under the conditions of condensed sowing and increased mineral nutrition.","PeriodicalId":36512,"journal":{"name":"Proceedings on Applied Botany, Genetics and Breeding","volume":"89 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141016268","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}
