... Exposure to triclosan (TCS) has been reported to reduce photosynthetic pigments, suppress photosynthesis, and inhibit growth in both prokaryotic and eukaryotic algae including Anabaena flos-aquae (a model cyanobacterium). In particular, cyanobacteria are more sensitive to TCS toxicity compared to eukaryotic algae possibly due to the structural similarity to bacteria (target organisms); however, wh ...
... Albinism is a heterogeneous group of genetically determined diseases associated with complete or partial disruption of melanin synthesis. There are various forms of hereditary albinism, including oculocutaneous albinism, ocular albinism, and different syndromic forms. The study analyzed a sample of patients (n = 90) with varied forms of albinism for the presence of pathogenic variants of the nucle ...

Abstract:
... The taxonomic position of Bacillus alkalicola was evaluated using phylogenetic and genome-based comparisons. In phylogenetic (based on 16S rRNA gene sequence) and phylogenomic (based on concatenation of protein-marker genes) trees, Bacillus alkalicola clade with the members of the genus Evansella. The amino acid identity (AAI) values suggested to reclassify Bacillus alkalicola as a member of the g ...

Abstract:
... A novel virus, tentatively named “sweetbriar rose curly-top associated virus” (SRCTaV), was identified in sweetbriar rose (Rosa rubiginosa) using high-throughput sequencing. The complete genome sequence of SRCTaV was determined and characterized. Phylogenetic analysis revealed that SRCTaV is closely related to members of the genus Waikavirus. ...

Abstract:
... Meteora sporadica is a protist species first described by Hausmann et al. (2002) in deep-sea sediments from the Sporades Basin, Eastern Mediterranean Sea. Due to its unusual morphology and locomotion, very different from those of other high-rank eukaryotic taxa, it was classified as an incertae sedis species. Unfortunately, its morphological characterization was not accompanied by the generation o ...

Abstract:
... The genus Streptomyces has been explored in industrial sectors due to its endurance to environmental stresses, the production of a plethora of biomolecules, the biological remediation of soils, and alleviating plant stresses. The whole genome of NGL1 and HMS4 was sequenced due to the specific laccase activity against 2,6-dimethoxyphenol (2,6-DMP) and differential plant beneficial attributes. The d ...

Abstract:
... A new bakuellid ciliate, Holostichides eastensis nov. spec. isolated from China, is investigated in terms of its morphology, ontogenesis, and molecular phylogenesis. It is characterized by size 150–180 µm × 45–60 µm in vivo; 27–46 macronuclear nodules; cortical granules dark brown, spherical, about 0.5 µm across, clustered in groups and then arranged longitudinally; three frontal cirri with one to ...

Abstract:
... Publication of the complete genome sequence of Arabidopsis thaliana, the first plant reference genome, in December 2000 heralded the beginning of the plant genome era. Over the past 20 years reference genomes have been generated for hundreds of plant species, spanning non-vascular to flowering plants. Releasing these plant genomes has dramatically advanced studies in all disciplines of plant biolo ...

Abstract:
... Since the completion of the rice genome sequencing project in 2005, we have entered the era of rice genomics, which is still in its ascendancy. Rice genomics studies can be classified into three stages: structural genomics, functional genomics, and quantitative genomics. Structural genomics refers primarily to genome sequencing for the construction of a complete map of rice genome sequence. This i ...

Abstract:
... AbstractThe international DNA sequence databases abound in fungal sequences not annotated beyond the kingdom level, typically bearing names such as “uncultured fungus”. These sequences beget low-resolution mycological results and invite further deposition of similarly poorly annotated entries. What do these sequences represent? This study uses a 767,918-sequence corpus of public full-length funga ...

Abstract:
... VITEK®2, MALDI-TOF MS and 16S rRNA sequencing were evaluated for the identification of aerobic endospore-forming bacteria (AEB) from a pharmaceutical facility. MALDI-TOF MS demonstrated higher accuracy compared to VITEK®2, although both databases were insufficient to identify AEB species. Sequencing was the best methodology, but unable to identify closely related species. ...

Here, we report the chromosome-level genome sequence of A. luchuensis mut. kawachii IFO 4308 (NBRC 4308) and a comparison of the sequence with that of A. luchuensis RIB2601. The genome of strain IFO 4308 was assembled into nine contigs consisting of eight chromos ...

Abstract:
... Fibricola and Neodiplostomum are diplostomid genera with very similar morphology that are currently separated based on their definitive hosts. Fibricola spp. are normally found in mammals, while Neodiplostomum spp. typically parasitize birds. Previously, no DNA sequence data was available for any member of Fibricola. We generated nuclear ribosomal and mtDNA sequences of Fibricola cratera (type-spe ...

Abstract:
... The artificial 601 DNA sequence is often used to constrain the position of nucleosomes on a DNA molecule in vitro. Although the ability of the 147 base pair sequence to precisely position a nucleosome in vitro is well documented, application of this property in vivo has been explored only in a few studies and yielded contradictory conclusions. Our goal in the present study was to test the ability ...

Abstract:
... The present review concerns the diversity of prions (proteinaceous infectious particles) and the mechanisms of their reproduction. Various strains of the same prion are considered. We demonstrate that any prion strain regardless its molecular organization and species identity, under passaging on the isogenic homozygous background, is per se a virus-like hereditary factor. Its features depend on (i ...

The gene encoding the KAP1-3 protein (KRTAP1-3) has been described in goats, but little is known about sequence variation in this gene and if it affects cashmere fibre traits. In this study, we used a polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) technique to screen for nucleotide sequence variatio ...
