Genetic Techniques

Current pace of breeding technologies relies on a tighter control of quality and identity of breeding achievements. Thereby, standardised variety nomenclature becomes of particular relevance to store original genetic information and warrant authenticity of the breeding product. A nomenclature standard regulates the variety’s name and habitus. A herbarium specimen is most appropriate for standardisation, since it defines a set of strongly inherited morphological characters for a variety. Nomenclature standards must be permanently stored in a scientific herbarium collection. The N. I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) in alliance with national plant breeders initiated a first nomenclature standard collection of national-breeding cultivars. Aside to classical herbarising, the collection utilises molecular genetic techniques, particularly genotyping, to enable extended variety verification. The VIR team has developed the nomenclature standards of six apple varieties originated by the Crimean Experimental Breeding Station, a VIR Branch (Beloe Solntse, Zolotoy Potok, Kubanochka, Leto Krasnoe, Luchistoe and Shchedrost). The standards are supplemented with DNA barcodes obtained jointly with the N. I. Vavilov Institute of General Genetics. Fifteen microsatellite markers were used for barcoding. The herbarium nomenclature specimens adhered to the VIR-developed protocol in accordance with the International Code of Nomenclature for Cultivated Plants (ICNCP). The specimens are registered in the VIR Herbarium database and deposited in the World Crop Wild and Weed Relatives (WIR) Herbarium type collection.

In the herbarium of cultivated plants of the world, their wild relatives and weeds (WIR) a collection of nomenclatural standards for cultivars of domestic breeding is being created. Nomenclatural standards are carriers of the authenticity of the genetic information of the breeding achievements and should be kept indefinitely in the scientific herbarium collection. A herbarium sample collected with the direct participation of an expert, which can be the author of the cultivar or official representative of the author's breeding organization, is designated as the nomenclature standard. The nomenclatural standard confirms the originality of the cultivar, protects the copyright of its creators. The article publishes the nomenclature standards of 10 black currant (Ribes nigrum L.) cultivars, bred at Sverdlovsk Horticultural Breeding Station from 1983 to 1997 and included into the State Register of Breeding Achievements: Akkord (WIR-54112), Vasilisa (WIR-54115), Vympel (WIR-54118), Globus (WIR-54119), Dobry Dzhinn (WIR-54121), Pilot (WIR-54127), Slavyanka (WIR-54129), Udalets (WIR-54132), Fortuna (WIR-54133), Shaman (WIR-54134). In addition to the description of the nomenclature standards, the distinctive taxonomic and economically valuable traits of each cultivar are given. Herbarium samples of nomenclature standards are made in accordance with the recommendations of the International Code of Nomenclature for Cultivated Plants (ICNCP), registered in the database "VIR Herbarium" and included in the Herbarium of cultivated plants of the world, their wild relatives and weeds (WIR).

In the present paper, the potato cultivars bred at the Leningrad Research Institute for Agriculture “Belogorka”, were taken as an example for demonstrating the results of elaboration of methodological approaches that are currently developed at the N.I. Vavilov Institute of Plant Genetic Resources (VIR) for the preparing of nomenclatural standards and their genotyping. In 2018, joint research of VIR scientists and breeders from the Leningrad Research Institute for Agriculture “Belogorka” began in the field of preparing nomenclatural standards for potato cultivars bred at this institute. Nomenclatural standards were prepared according to the ‘International Code of Nomenclature for Cultivated Plants’. Plant material for herbarium specimens was collected in the experimental field of the “Belogorka” Institute in 2018 by cultivar authors and handed over to the VIR Herbarium of cultivated plants, their wild relatives and weeds (WIR). The plant material included stems with inflorescences and later - tubers of 21 cultivars which were bred at the “Belogorka” Institute. Two precultivars undergoing State variety testing and three breeding clones were also included in this study. Just before herbarium preparation, the obtained plant material was photographed, plant morphological characters described, and the results compared with the description given in such official documents as the “Cultivar Questionnaireˮ and “Description of selection achievementˮ. The nomenclatural standards of 21 cultivars registered in the VIR Herbarium Database and transferred for conservation to the VIR herbarium, are published in this paper. Before herbarium preparation, the plant material was sampled for DNA extraction and subsequent genotyping and molecular screening. The genetic passports include information about the polymorphism of 10 chromosome-specific microsatellite loci, as well as the data on the presence/absence of diagnostic fragments of 12 markers of the 11 R-genes conferring resistance to diseases and pests, and for some cultivars – the information about their cytoplasm type. These genetic passports are valuable not only because different types of DNA markers were used in their preparing (SSR, SCAR and CAPS markers of the R genes; markers specific to different loci of the nuclear and organelle genomes), but first of all because of the material itself, as the DNA samples were isolated from the plants with the assigned status of nomenclatural standard for each particular cultivar. Based on the genetic passports data, trueness to type of the “Belogorka” cultivar samples obtained from various sources was verified.

In order to preserve the genetic diversity of cultivars, it is recommended to develop documentation approaches through the registration of cultivar nomenclatural standards in accordance with the International Code of Nomenclature for Cultivated Plants. The N.I Vavilov Institute of Plant Genetic Resources keeps developing this approach along with the DNA marker technologies: SSR genotyping and molecular screening with DNA markers of genes controlling valuable traits. In 2018, VIR, together with the leading national centre for potato breeding – the A.G. Lorkh All-Russian Scientific-Research Institute of Potato Farming (now the A.G. Lorkh Russian Potato Research Center), initiated the preparation of nomenclatural standards for potato cultivars bred both at the A.G. Lorkh institute and in co-authorship with other breeding institutions. This paper presents 30 nomenclatural standards which are maintained in the Nomenclature standard fund of the Herbarium of cultivated plants and their wild relatives and weeds (VIR Herbarium, WIR). Also, the paper presents genetic passports of the mentioned 30 cultivars, developed using DNA samples extracted from the plant material of nomenclatural standards. Genetic passports include information about the polymorphism of the 8 chromosome-specific microsatellites and data on the results of molecular screening with 15 markers of 11 genes conferring resistance to the most dangerous pathogens and pests: potato viruses Y and X, late blight and potato cyst nematodes. A comparison of SSR-profiles of nomenclatural standards with those of 66 cultivar samples obtained from various sources made it possible to verify authenticity and homogeneity of the latter.

Oat Breeding

Cereal grains provide half of the calories consumed by humans. In addition, they contain important compounds beneficial for health. During the last years, a broad spectrum of new cereal grain-derived products for dietary purposes emerged on the global food market. Special breeding programs aimed at cultivars utilizable for these new products have been launched for both the main sources of staple foods (such as rice, wheat, and maize) and other cereal crops (oat, barley, sorghum, millet, etc.). The breeding paradigm has been switched from traditional grain quality indicators (for example, high breadmaking quality and protein content for common wheat or content of protein, lysine, and starch for barley and oat) to more specialized ones (high content of bioactive compounds, vitamins, dietary fibers, and oils, etc.). To enrich cereal grain with functional components while growing plants in contrast to the post-harvesting improvement of staple foods with natural and synthetic additives, the new breeding programs need a source of genes for the improvement of the content of health benefit components in grain. The current review aims to consider current trends and achievements in wheat, barley, and oat breeding for health-benefiting components. The sources of these valuable genes are plant genetic resources deposited in genebanks: landraces, rare crop species, or even wild relatives of cultivated plants. Traditional plant breeding approaches supplemented with marker-assisted selection and genetic editing, as well as high-throughput chemotyping techniques, are exploited to speed up the breeding for the desired genotуpes. Biochemical and genetic bases for the enrichment of the grain of modern cereal crop cultivars with micronutrients, oils, phenolics, and other compounds are discussed, and certain cases of contributions to special health-improving diets are summarized. Correlations between the content of certain bioactive compounds and the resistance to diseases or tolerance to certain abiotic stressors suggest that breeding programs aimed at raising the levels of health-benefiting components in cereal grain might at the same time match the task of developing cultivars adapted to unfavorable environmental conditions.

AbstractRelation between morphological traits of the root system and yield related traits is an important issue concerning efforts aiming at improving of ideotype of cultivated plants species, including pea. In this paper, to analyse the dependency between traits describing the root system morphology and yield potential, Person’s andSpearman's_correlations as well as canonical correlations were used.Root system was analyzed in 14 and 21 day-old seedlings growing in blotting-paper cylinders. Yield potential of pea was analysed in a field experiment. Results of Person’s and Spearman's_correlations revealed that number of lateral roots and lateral roots density were correlated witch yield related traits. Correlation between root length and shoot length was observed only for 14 day-old seedlings. The result of canonical correlations revealed that number of lateral roots and lateral roots density had the largest effect on yield related traits. This work highlights, that in order to improve the yield of pea it might become necessary to understand genetic determination of morphological traits of the root system, especially number of lateral roots.

Among the chronicles relating the heroism of the besieged Leningrad, there are pages dedicated to the deeds performed by the staff the world-famous All-Union Research Institute of Plant Industry (VIR, now the N.I. Vavilov All-Russian Institute of Plant Genetic Resources). With the beginning of the war, even before the city was surrounded by the Nazi troops, the government decided to evacuate a number of factories and institutes from Leningrad, including VIR, but the plan failed. Only in winter did the Institute start partial evacuation, although preparations had been going on for a long time. The largest and most important part of the collection was left behind in the besieged city. The remaining employees were forced to work under the hardest conditions of the siege, in unheated premises. In the harsh reality of the winter in 1941–1942, the daily bread rationing was cut down, and hunger raged in the city, killing tens of thousands of city residents, including VIR employees who kept the stored seeds and tubers untouched. The most difficult part was preserving the potato collection. In the spring of 1942, preparations were made for sowing to restore the viability of seeds and tubers in the fields of Leningrad’s suburban area under the fire from the enemy artillery. Only the heroic efforts of VIR’s staff helped to save the collection from destruction and loss of germination. This heroism cost more than 20 experts and scientists their lives. So, the most dangerous period for the Institute was overcome at such price. Immediately after the siege was lifted, a group of experts was sent to Leningrad from Krasnoufimsk to help with selecting seed accessions for urgent reproduction. Working under extreme physical exhaustion in frozen premises, without water or electricity, under continuous shelling, they saved, many at the cost of their own lives, the collection of cultivated plants and their wild relatives, the herbarium, and the scientific library for future generations.

Abstract Rare renal diseases (RRD) are an important category of rare disease (RD) as they can do great damage to the patients, families and society. The patient may undergo years even decades of numerous investigations including invasive procedures and yet not have definitive and precise diagnose and therefore, no opportunity for appropriate treatment. The great progress in molecular genetic techniques characterized many Mendelian diseases on molecular level. This gave the possibility for appropriate prevention and treatment interventions, genetic counseling and prenatal diagnosis. Herein, we summarize the current status of RRD in Macedonia. The research interest of Macedonian clinicians and scientists is focused on the genetics of congenital anomalies of the kidney and urinary tract (CAKUT), steroid resistant nephrotic syndrome, nephrolithiasis and nephrocalcinosis, cystic diseases and cilliopathies with collaborations with eminent laboratories in Unites States and Europe. This collaboration resulted in detection of new genes and pathophysiological pathways published in The New England Journal of Medicine and in other high impact journals. Macedonian health professionals have knowledge and equipment for diagnosis of RRD. Unfortunately the lack of finances is great obstacle for early and appropriate diagnosis. Participation in the international registries, studies and trials should be encouraged. This would result in significant benefit for the patients, health professionals and science.
