Genomic characterization of Haemophilus influenzae : a focus on the capsule locus. Background: Haemophilus influenzae (Hi) can cause invasive diseases such as meningitis, pneumonia, or sepsis.. Methods: A total of 395 typeable and 293 NTHi isolates were characterized by whole genome sequencing (WGS).. Pair- wise comparisons were used to evaluate the capsule loci. NTHi isolates were genetically diverse, with seven...

population structure, and genetic diversity in the U.S. peanut mini core collection. We report an analysis of linkage disequilibrium (LD), population structure, and genetic diversity, and examine the ability of GWA to infer marker-trait associations in the U.S. Results: LD persists over long distances in the collection, decaying to r 2 = half decay distance at 3.78 Mb. These results...

We found an evidence of admixture between Tibetan chickens and other domestic population. By comparing the genomes of the Tibetan and lowland fowls, we identified genes associated with high-altitude adaptation in Tibetan chickens were mainly involved in energy metabolism, body size maintenance and available food sources.. Since the domestication of the red jungle fowl (Gallus gallus) (approximately 8000 to 5400...

Comparison of the endolysins reveals multi-domain modularity, with conservation of the SH3 cell wall binding domain.. Phages are able to kill 50% of the bacteria produced every 48 h, playing a major role in microbial ecology and in the evolution of bacterial genomic struc- tures through horizontal gene transfer (HGT), including virulence factors [8].. 2019 Open Access This article is...

Background: Since domestication, chickens did not only disperse into the different parts of the world but they have also undergone significant genomic changes in this process. Many breeds, strains or lines have been formed and those represent the diversity of the species. As part of the SYNBREED project, samples from a wide variety of chicken populations have been collected across...

Genome-wide study on genetic diversity and phylogeny of five species in the genus Cervus. eldii) in the genus Cervus were analyzed using reduced-representation genome sequencing.. Phylogenetic ML tree of all Cervus based on the 21 SNP matrices showed 5 robustly supported clades that clearly separate C. In the C.. Phylogenetic reconstruction indicated that the first evolutionary event of the genus...

In the past decade, significant progress has been made in pear molecular genetics based on DNA research, but the number of molecular markers is still quite limited, which hardly satisfies the increasing needs of geneticists and breeders.. A total of 101,694 pairs of SSR primers were designed from the SSR loci, and 80,415 of the SSR loci were successfully located...

Genomic diversity of Areca Palm Velarivirus 1 (APV1) in Areca palm ( Areca catechu. The APV1 isolates had highly conserved sequences in seven open reading frames (ORFs. 95% nucleotide [nt] identity) at the 3 ′ terminal, but there was diversity (81 – 87% nt identity) in three ORFs at the 5 ′ terminal. Phylogenetic analysis divided the APV1 isolates into...

Genetic diversity and agronomic performance of Slovenian landraces of proso millet (Panicum miliaceum L.). Panicum miliaceum L., most commonly named proso millet and broomcorn millet, is a member of the small millets group, which together with P. proso millet has a 30% share of global millet production. Proso millet is grown for the production of small seeds, which are used...

Genetic characterization of field populations of Culex pipiens Linnaeus, 1758 (Diptera: Culicidae) sampled from the Aegean region of Turkey. Khan et al., 2010. Of the currently known approximately 500 arboviruses, more than 200 are known or suspected to be mosquito-borne. Due to its appropriate climatic and other ecological features required for breeding and living of mosquitoes, Turkey hosts 50 mosquito...
