Background. The XRQ sunflower genome has been sequenced but not yet fully annotated, and all candidate genes for most traits have identified. Disclosing the relationships among in this study will help to understand genetic control over phenotypic characters. Materials methods . A set of 237 lines from VIR’s collection was phenotyped their morphological characters (plant height; branching type; shapes sizes leaf, petiole, flower head, disk ray florets; downy mildew damage rate) genotyped with...
Background. The CMS- Rf genetic system based on the PET1-type cytoplasmic male sterility (CMS) is commonly used to create commercial sunflower ( Helianthus annuus ) hybrids. Rf1 gene, of key importance for hybrid breeding, necessary restoring pollen fertility in F 1 plants. molecular markers tested various materials are an effective tool identifying parental line genotypes at locus, controlling homogeneity, and determining purity seed lots. In present study, allele-specific candidate genes...
Sunflower is an important oilseed crop domesticated in North America approximately 4000 years ago. During the last century, oil content sunflower was under strong selection. Further improvement of properties achieved by modulating its fatty acid composition one main directions modern breeding.We searched for genetic basis variation genotyping 601 inbred lines and assessing their lipid composition. Our genome-wide association analysis based on genotypes 15,483 SNPs concentrations 23 acids,...
Modern breeding of sunflower ( Helianthus annuus L .), which started 100 years ago, increased the number and diversity cultivated forms. In addition, for more than 50 years, wild other species have been collected in North America where they all originated. Collections both forms are maintained gene banks many countries is an important crop, with some specificity according to availability germplasm local research programmes. Cultivated material includes land races, open pollinated varieties,...
The phenomenon of cytoplasmic male sterility (CMS), consisting in the inability to produce functional pollen due mutations mitochondrial genome, has been described more than 150 plant species. With discovery nuclear fertility restorer (Rf) genes capable suppressing CMS phenotype, it became possible use CMS-Rf genetic systems as basis for practical utilization heterosis effect various crops. Seed production sunflower hybrids all over world is based on extensive PET1 combined with Rf1 gene. At...
This review is devoted to the description of chemical peculiarities industrial oil crops cultivated (or prospective for cultivation) in Russia, which are stored VIR collection. Different have similar fatty acids biosynthesis pathways, but each species has its own individualities composition and genetic control. The diversity crop opens possibility multipurpose utilization practically all segments. Sunflower, rapeseed, flax, mustard, camelina safflower Russia as crops. Castor beans, perilla,...
Domestic pigs were inoculated with 50 (low) or 5000 (high) haemadsorbing doses (HAD50) via intranasal (IN) intramuscular (IM) routes, to investigate the pathogenesis of 5 Russian isolates African Swine Fever Virus (ASFV) collected in 2013. Several clinical and virological parameters (including hemorrhagic syndrome, body fever gross microscopic lesions) identical between high low dose groups for all isolates, whereas duration pyrexia, incubation Original Research Article Vlasova et al.; BMRJ,...
More than 70 cytoplasmic male sterility (CMS) types have been identified in Helianthus, but only for less half of them, research mitochondrial organization has conducted. Moreover, complete mitochondrion sequences published two CMS sources – PET1 and PET2. It demonstrated that other sunflower like MAX1, significantly differ from the PET2 types. However, possible molecular causes induction by MAX1 not yet proposed. In present study, we investigated structural changes genome HA89 (MAX1) line...
The results of a long-term program aimed at discovering the hidden potential and genetic variation sunflower accessions in germplasm collection creation set homozygous lines are presented. A has different levels development:
Background Cytoplasmic male sterility (CMS) is a common phenotype in higher plants, that often associated with rearrangements mitochondrial DNA (mtDNA), and widely used to produce hybrid seeds variety of valuable crop species. Investigation the CMS phenomenon promotes understanding fundamental issues nuclear-cytoplasmic interactions ontogeny plants. In present study, we analyzed structural changes genomes three alloplasmic lines sunflower ( Helianthus annuus L.). The investigation was...
The investigation of DNA markers associated with the pollen fertility restoration gene (Rf1) was conducted in Helianthus. Two sequence-characterized amplified region (SCAR) - HRG01 and HRG02 were informative for identification Rf1 selections sunflower plants. codominant character marker amplicon polymorphism has been determined. Five annual twenty-six perennial species tested presence Rf genotypes. proved to be a more appropriate determination species, species. We have also developed...
Abstract America is the center of origin annual sunflower
This study provides insights into the flexibility of mitochondrial genome in sunflower (Helianthus annuus L.) as well causes ANN2-type cytoplasmic male sterility (CMS). De novo assembly male-sterile HA89(ANN2) line was performed using high-throughput sequencing technologies. Analysis CMS ANN2 DNA sequence revealed following reorganization events: twelve rearrangements, seven insertions, and nine deletions. Comparisons coding sequences from with male-fertile identified a deletion orf777 new...
Background. In breeding work, it is necessary to take into account such an important feature as male sterility of the hybrids obtained. If a plant has visually visible anthers and pollen, quality pollen grains themselves may be low. It carry out not only visual analysis, but also cytological study in order properly assess reproductive potential plants. Materials methods. Wild species, some cultivars, lines sunflower from collection N. I. Vavilov All-Russian Institute Plant Genetic Resources...
Isolation of African swine fever virus (ASFV) is a critical step towards the identification, titration, characterization, and even modification virus. Therefore, it important to identify suitable cell line that supports efficient replication ASFV for these purposes. This should be achieved when starting with low load, as in case isolating from field samples. article presents detailed protocol on preparation porcine bone marrow primary (PBMP) culture, which has high sensitivity ASFV,...
The significant difference in the mtDNA size and structure with simultaneous slow evolving genes makes mitochondrial genome paradoxical among all three DNA carriers plant cell. Such features make investigations of particular interest. genus Helianthus is a diverse taxonomic group, including at least two economically valuable species-common sunflower (H. annuus) Jerusalem artichoke tuberosus). successful investigation nuclear provided insights into some genomics aspects significantly...
Background. Modern production of sunflower seeds is currently based on the cultivation high-yielding heterotic F 1 hybrids from crossbreeding lines with cytoplasmic male sterility (CMS) PET1-type and fertility restorer lines. The paternal parent serves as a donor nuclear Rf1 gene functional allele, which responsible for pollen restoration in plants. detection carriers locus recessive dominant alleles using diagnostic molecular markers accelerates breeding female parental creating hybrids....
