DNAfingerprinting, etc ; forensic sciences; loci; weight-of-evidence; Show all 4 Subjects
Abstract:
... The initial version of DNAStatistX calculated likelihood ratios (LRs) using only loci present in both the trace and reference profiles, thereby ignoring loci from the trace that are not present in the reference. Here, DNAStatistX was adapted to include all trace loci. At loci missing in the reference, an unknown contributor was invoked. Although this strategy is already incorporated in other syste ...

Abstract:
... Shark depredation is a worldwide yet not well understood problem that is responsible for economic losses in both commercial and recreational fisheries. We collaborated with fishers from the Mariana Islands in the western Pacific to identify depredating shark species via mitochondrial DNA (mtDNA) barcoding of partially consumed fish from real‐world depredation events. Trained fishers collected swab ...

Abstract:
... This survey reports on the DNA identification and occurrence of Culex torrentium and Cx. pipiens s.s. in Belgium. These native disease-vector mosquito species are morphologically difficult to separate, and the biotypes of Cx. pipiens s.s. are morphologically indistinguishable. Culex torrentium and Cx. pipiens s.s. were identified using the COI and ACE2 loci. We recorded 1248 Cx. pipiens s.s. and 4 ...

Abstract:
... High-copy tandemly organized repeats (TRs), or satellite DNA, is an important but still enigmatic component of eukaryotic genomes. TRs comprise arrays of multi-copy and highly similar tandem repeats, which makes the elucidation of TRs a very challenging task. Oxford Nanopore sequencing data provide a valuable source of information on TR organization at the single molecule level. However, bioinform ...
... This work has aimed to create a PCR test to identify avian and mammalian DNA in meat products. The test is based on phylogenetic analysis of 18S ribosomal RNA (rRNA) of four major groups of Tetrapod: Amphibia, Reptilia, Mammalia, and Aves. 18S rDNA complete coding sequences from GenBank have been used for phylogenetic analysis by the Maximum Likelihood method. The alignment of these 18S rDNA seque ...

Abstract:
... DNA methylation is an important feature of gene epigenetics that affects the metabolic process of organisms. Although surface-enhanced Raman spectroscopy (SERS) has demonstrated great potential in label-free DNA detection, discriminating the various processes involved in DNA methylation remains a challenge. DNA molecules fold themselves, wrapping the hydrophobic bases, thus making it difficult for ...

Abstract:
... Mounting evidence points to a linkage between biodiversity and ecosystem functioning (B‐EF). Global drivers, such as warming and nutrient enrichment, can alter species richness and composition of aquatic fungal assemblages associated with leaf‐litter decomposition, a key ecosystem process in headwater streams. However, effects of biodiversity changes on ecosystem functions might be countered by th ...
... City parks of Vinnytsia, Ukraine, were examined for the occurrence of host‐seeking ticks and collected specimens were examined for presence of rickettsial pathogens. In the summer season, the only collected individuals were Dermacentor reticulatus adults (n = 203). DNA identification of pathogens was conducted with the use of 16S rRNA gene amplification. Molecular analyses confirmed the presence o ...
... Asiatic cotton (G. arboreum) is one of the important cultivated species of cotton originated in Indian subcontinent. Owing to its climate resilience, Asiatic cotton in particular and desi cotton in general, constitutes valuable genetic resources for cotton improvement to achieve sustainable cotton production in India. In the present study, 24 popular Asiatic cotton varieties were profiled using 30 ...

Abstract:
... Recombinase polymerase amplification (RPA) is a useful pathogen identification method. Several label-free detection methods for RPA amplicons have been developed in recent years. However, these methods still lack sensitivity, specificity, efficiency, or simplicity. In this study, we propose a rapid, highly sensitive, and label-free pathogen assay system based on a solid-phase self-interference RPA ...
DNAfingerprinting, etc ; DNA; models; mutants; nanopores; Show all 5 Subjects
Abstract:
... A biological nanopore is one of the predominant single-molecule approaches as a result of its controllable single-biomolecule interface, which could reflect the “intrinsic” information on an individual molecule in a label-free way. Because the current blockage is normally treated as the most important parameter for nanopore identification of every single molecule, the fluctuation of current blocka ...
DNAfingerprinting, etc ; DNA; Rubus; botany; fields; journals; loci; Show all 7 Subjects
Abstract:
... Beek (2016) argued that Rubus aetnicus Cupani ex Weston was the correct name of the taxon that was then called R. canescens DC., and which was previously known as R. tomentosus Borkh. Moreover, R. canescens was stated to be not identical with R. aetnicus, but rather a form of R. × collinus DC. Matzke‐Hajek (2016) raised objections to both statements. Therefore, the aim of this study was to thoroug ...
DNAfingerprinting, etc ; DNA; Y chromosome; genes; humans; males; monophyly; phylogeography; Show all 8 Subjects
Abstract:
... The Y chromosome is a unique tool for studying the structure of gene pools and the evolutionary history of human populations. Patrilinearity ensures the sequential accumulation of mutations, as a result of which the Y chromosome is a fairly simple marker system for reconstructing evolutionary changes, migration, and other demographic processes in human populations. The analysis of Y-chromosome hap ...

Abstract:
... The twisted growth of organs is a distinctive and attractive trait for woody plants. A bud mutant with twisted branches was discovered from ‘Dongzao’, the most popular and tasty table cultivar of Chinese jujube (Ziziphus jujuba Mill.). This study explored the morphological and nutritional characteristics and SSR marker changes of the novel variant. Compared to its mother plant and an external cont ...

Abstract:
... In cases involving identification of missing persons, mass disasters and ancient DNA investigations, bone and teeth samples are often the only, and almost always the best, biological material available for DNA profiling. Standard methods for extraction of DNA from such samples involve grinding of the bone and teeth samples. Here, we present an extremely efficient protocol for recovery of DNA from ...

A total of 254 Bradyrhizobium strains were isolated from 97 soybean samples (9 cultivars) collected in 14 regions. B. elkanii dominated in the southern regions, while B. diazoefficiens dominated in most central and northern regions. Through non-parametric multidime ...

... Onion (Allium cepa L.) is one of the most important bulbous vegetable used in global kitchen. Although it has various important traits but among them the high total soluble solid content (HTSS) of white onion is highly preferred by the industries for processing purpose. Looking into the broader use of the white onion; we utilized a total of 23 polymorphic simple sequence repeats (SSRs) and intron ...

Abstract:
... In the breeding season f 2018, we found a much larger egg in one nest of Cinereous Tit (Parus cinereus) in Zuojia Nature Reserve, Jilin Province, China. The tit pair abandoned their nest soon after the alien egg hatched, which resulted in the death of the foreign chick. Based on DNA identification, this foreign chick was confirmed as a Great Spotted Woodpecker (Dendrocopos major), suggesting that ...

Abstract:
... AIMS: We investigated whether individuals of Silene paradoxa L., grown in serpentine and non-serpentine soils, displayed variation in functional traits and adaptive strategies together with a differentiation of the gene pool. We hypothesised that individuals growing in serpentine sites may be exposed to a higher degree of stress, resulting in measurable differences in leaf traits and adaptive stra ...
