BACKGROUND: Deleterious mutations in PRF1 result in lethal, childhood disease, familial hemophagocytic lymphohistiocytosis type 2 (FHL 2). However, not all mutations in PRF1 are deleterious and result in FHL 2. Currently, these nondeleterious mutations are being investigated in the onset of numerous disorders, such as lymphomas and diabetes. Yet, there is still an overwhelmingly large amount of PRF1 mutations that are not associated with disease. METHODS: We conducted a post hoc analysis of the PRF1 mutations in the coding region using the recently published Exome Aggregation Consortium genomes, Leiden Open Variation Database, NCBI SNP database, and primary literature to better understand PRF1 variation in the human population...

Kopal Singhal, Sujata Mohanty
Multiple toxin-antitoxin (TA) systems are housed in different locations within the bacterial genome and are known to be associated with various cellular processes and stress-related adaptation. In endosymbionts, although, the TA system has scarce occurrence but studies have highlighted its presence in enhancing host-symbiont interactions. Wolbachia, an obligate endosymbiont, has recently been proposed as a biocontrol agent which may be helpful in controlling vector-borne diseases. There are reports suggesting the role of TA system in inducing cytoplasmic incompatibility in case of Wolbachia, however, the underlying mechanism is still not known...

Crested wheatgrass [Agropyron cristatum L. (Gaertn.)] is an important cool-season forage grass widely used for early spring grazing. However, the genomic resources for this non-model plant are still lacking. Our goal was to generate the first set of next generation sequencing data using the genotyping-by-sequencing technique. A total of 272 crested wheatgrass plants representing seven breeding lines, five cultivars and five geographically diverse accessions were sequenced with an Illumina MiSeq instrument. These sequence datasets were processed using different bioinformatics tools to generate contigs for diploid and tetraploid plants and SNPs for diploid plants...

The versatile soil bacterium Anaeromyxobacter dehalogenans lacks the hallmark denitrification genes nirS and nirK (NO2-→NO), and couples growth to NO3- reduction to NH4+ (respiratory ammonification) and to N2O reduction to N2A. dehalogenans also grows by reducing Fe(III) to Fe(II), which chemically reacts with NO2- to form N2O (i.e., chemodenitrification). Following the addition of 100 μmoles of NO3- or NO2- to Fe(III)-grown, axenic cultures of A. dehalogenans, 54 (±7) μmoles and 113 (±2) μmoles N2O-N, respectively, were produced and subsequently consumed...

The apicomplexan protozoans Eimeria spp. cause coccidioses, the most common intestinal diseases in chickens. Coccidiosis is associated with significant animal welfare issues and has a high economic impact on the poultry industry. Lack of a full understanding of immunogenic molecules and their precise functions involved in the Eimeria life cycles may limit development of effective vaccines and drug therapies. In this study, immunoproteomic approaches were used to define the antigenic protein repertoire from the total proteins of unsporulated Eimeria tenella oocysts...

The powdery mildew fungus, Blumeria graminis f. sp. hordei is a worldwide threat to barley (Hordeum vulgare L. ssp. vulgare) production. One way to control the disease is by the development and deployment of resistant cultivars. A genome-wide association study was performed in a Nordic spring barley panel consisting of 169 genotypes, to identify marker-trait associations significant for powdery mildew. Powdery mildew was scored during three years (2012-2014) in four different locations within the Nordic region...

Mitsuharu Sato, Kentaro Miyazaki
Horizontal gene transfer (HGT) is a ubiquitous genetic event in bacterial evolution, but it seldom occurs for genes involved in highly complex supramolecules (or biosystems), which consist of many gene products. The ribosome is one such supramolecule, but several bacteria harbor dissimilar and/or chimeric 16S rRNAs in their genomes, suggesting the occurrence of HGT of this gene. However, we know little about whether the genes actually experience HGT and, if so, the frequency of such a transfer. This is primarily because the methods currently employed for phylogenetic analysis (e...

BACKGROUND: Bacterial carbohydrate metabolism is extremely diverse, since carbohydrates serve as a major energy source and are involved in a variety of cellular processes. Bacterial genes belonging to same metabolic pathway are often co-localized in the chromosome, but it is not a strict rule. Gene co-localization in linked to co-evolution and co-regulation. This study focuses on a large-scale analysis of bacterial genomic loci related to the carbohydrate metabolism. RESULTS: We demonstrate that only 53% of 148,000 studied genes from over six hundred bacterial genomes are co-localized in bacterial genomes with other carbohydrate metabolism genes, which points to a significant role of singleton genes...

BACKGROUND: The class of fluoroquinolone antibiotics, due to its core chemical modifications, is considered as wide-spectrum antibacterial drugs with useful pharmacokinetic and pharmacodynamic properties. However, because of their poor solubility in water, they are used as salts (lactates or hydrochlorides). Fluoroquinolones, bacterial membranes and eukaryotic cell membranes interactions are well known and their permeation properties are well investigated. In fact, they are concentrated inside the cells and intracellular compartments...
