Resumen
ABSTRACT The rfb region specifies the structure of lipopolysaccharide side chains that comprise the diverse gram-negative bacterial somatic (O) antigens. The rfb locus is adjacent to gnd, which is a polymorphic gene encoding 6-phosphogluconate dehydrogenase. To determine if rfb andgnd cotransfer, we sequenced gnd in five O55 and 13 O157 strains of Escherichia coli. E. coli O157:H7 has a gnd allele (allele A) that is only 82% identical to the gnd allele (alleleD) of closely related E. coli O55:H7. In contrast, gnd alleles of E. coli O55 in distant lineages are >99.9% identical to gnd alleleD

Resumen
Abstract In yeast meiotic recombination, alleles used as genetic markers fall into two classes as regards their fate when incorporated into heteroduplex DNA. Normal alleles are those that form heteroduplexes that are nearly always recognized and corrected by the mismatch repair system operating in meiosis. High PMS (postmeiotic segregation) alleles form heteroduplexes that are inefficiently mismatch repaired. We report that placing any of several high PMS alleles very close to normal alleles causes hyperrecombination between these markers. We propose that this hyperrecombination is caused by t

Resumen
A polymorphism in the promoter of human NRAMP1 encodes a Z-DNA forming dinucleotide repeat with four alleles: (1) t(gt)5ac(gt)5ac(gt)11g; (2) t(gt)5ac(gt)5 ac(gt)10g; (3) t(gt)5ac(gt)5ac(gt)9g; and (4) t(gt)5ac(gt)9g. Alleles 1 and 4 are rare (gene frequencies ∼0.001); alleles 2 and 3 occur at gene frequencies ∼0.20−0.25 and ∼0.75− 0.80, respectively. Here, luciferase reporter gene constructs are used to show that the four alleles differ in their ability to drive gene expression. In the absence of exogenous stimuli, alleles 1, 2, and 4 are poor promoters; allele 3 drives high expression, indic

Resumen
Abstract The RpII215 locus encodes the large subunit of RNA polymerase II (polII). Three of 22 RpII215 alleles cause a synergistic enhancement of the mutant phenotype elicited by mutations in the Ultrabithorax (Ubx) locus. We have recovered and analyzed three new mutations that suppress this enhancement. All three mutations map to the RpII215 locus. In addition to suppressing the Ubx enhancement of other RpII215 alleles, two of the new mutations, JH1 and WJK2, themselves enhance Ubx. RpII215 alleles can be placed into three classes based on their ability to enhance Ubx. Class I alleles, includ

Abstract Background: Cytochrome P450-dependent monooxygenase 2D6 (CYP2D6) activity can be estimated by investigating the metabolism of model drugs or by genotyping the most common CYP2D6 alleles. For Caucasians, the CYP2D6 allele frequencies are well investigated, and single-step assays are available for genotyping, whereas allele analysis in mainland Chinese is limited. Methods: Two tetra-primer assays and one allele-specific amplification assay were developed to easily genotype the CYP2D6 alleles *8, *10, and *14 previously detected in Asians.

Abstract Tumor necrosis factor (TNF) is a pro-inflammatory cytokine that plays a variety of roles in immune regulation and disease. The TNF regulatory region contains numerous SNPs some of which affect expression. We previously identified nine alleles of TNF promoter region from random samples, but allele frequencies in different populations and diversity of the gene, as well as expression levels driven by the promoter alleles are not known. The TNF promoter and gene were sequenced from 82 random healthy White individuals. Three novel promoter alleles and two novel SNPs were identified. Novel

Resumen
Cancer is a leading cause of death worldwide. This somatic cell genetic disease is characterized by progressive accumulation of mutations in multiple genes. An important characteristic of cancer cells is an increased rate of gains and losses of chromosomes, termed Chromosomal Instability (CIN). One of the frequently mutated genes in a variety of cancers is FBXW7 (F-Box and WD repeat domain-containing 7), encoding the substrate-recognition component of a ubiquitin ligase complex. Fbxw7 targets a number of oncoproteins such as, Cyclin E, c-Myc, Notch1 and Aurora A for ubiquitin mediated degradat

Resumen
DNA topological stress impedes normal DNA replication. If topological stress is allowed to build up in front of the replication fork, the fork rotates to overcome the stress, leading to formation of DNA pre-catenanes. The formation of DNA pre-catenanes is therefore a marker of DNA topological stress. In this study, I have examined how transcription linked DNA topological stress impacts on fork rotation and on endogenous DNA damage. Transcription, similar to replication, affects the topology of the DNA; and collision between the two machineries is likely to lead to high levels of DNA topologica

Resumen
Determination the photoperiod-insensitive allele (Ppd-D1a) in wheat cultivars is necessary for use in breeding development of newly wheat cultivars. The aim of our study was to select breeding material by screening Ppd-D1 gene alleles and estimation value and the degree of heterosis in F1. Using these two methods, it is possible to select genetic material for increased breeding of new wheat lines that combine earliness and increased productivity. In this study 26 varieties of spring soft wheat were screened for the Ppd-D1 gene alleles. The Ppd-D1a allele was detected in 12 wheat varieties (ITM

Resumen
The purpose of the work was to investigate the association of individual allelic variants of the polymorphic loci of genes IFNL3 (rs8099917 T/G) and IFNL4 (rs12979860 C/T) with the se-verity of COVID-19. No reliable association was found between individual allelic variants and T/G or C/T alleles of these loci of IFNL3 and IFNL4 with the severity of COVID-19 in residents of the Moscow region.

Resumen
The development of marker-associated breeding requires the development of DNA marker systems that meet the needs of the breeding process. We are looking for the opportunities to improve the efficiency of breeding for high oleic acid content in sunflower oil. One of the directions is the improvement of the existing marker system for detection the heterozygous status of the alleles of the FAD 2-1 gene. We carried out the search for information published in databases on this DNA locus. We studied the structure of the nucleotide sequences of the mutant allele and the wild-type allele. We proposed

Resumen
Individual loci affecting economic traits in dairy cattle (ETL) have been detected via linkage to genetic markers by application of the granddaughter design in the US population and the daughter design in the Israeli population. From these analyses it is not possible to determine allelic frequencies in the population at large, or whether the same alleles are segregating in different families. We proposed to answer this question by application of the "modified granddaughter design", in which granddaughters with a common maternal grandsire are both genotyped and analyzed for the economic traits.

Resumen
The hypothalamic melanocortin system plays a central role in the regulation of food consumption and energy homeostasis in mammals. Accordingly, our working hypothesis in this project was that genetic editing of the mc4r gene, encoding Melanocortin Receptor 4 (MC4R), will enhance food consumption, feed efficiency and growth in fish. To test this hypothesis and to assess the utility of mc4r editing for the enhancement of feed efficiency and growth in fish, the following objectives were set: Test the effect of the mc4r-null allele on feeding behavior, growth, metabolism and survival in zebrafish.
