Aphis glycines Matsumura (Hemiptera: Aphididae) can reduce the yield of aphid-susceptible soybean (Glycine max (L.) Merrill) cultivars. The Rag1 and Rag2 genes conferresistance to some biotypes of A. glycines. These genes individually can limit population growth of A. glycines and prevent yield loss. The impact of these genes when combined is not known. We compared the development of A. glycine...

The nucleotide sequences of a region including S1, S2, 3a, 3b and E genes of twenty-seven infectious bronchitis virus (IBV) isolates in Korea between 1990-2011 were determined and phylogenetic and computational recombination analyses were conducted. The sizes of coding regions of some genes varied among IBV isolates due to deletion or insertion of nucleotides; the nucleotide similarities of S1,...

Background: Avian infectious bronchitis (IB), with avianinfectious bronchitis virus (IBV) as the causing agent, is a ubiquitous endemicdisease of the chicken with devastating effects on its industry. A viralmembrane surface protein called S  notonly induces neutralizing antibodies but also plays an important role in virusbinding and entry to host cells. Technically, S1 protein gene sequencing a...

One IBV isolate, SC021202, was isolated from the kidneys of the infected young chickens by inoculating embryonated eggs, and its morphology, physiochemical and haemagglutonating properties were detected. Virulence of the isolate SC021202 was determined with specific pathogen-free (SPF) chicken inoculation. Nucleotide acid sequence of S1 gene of the isolate SC021202 was further sequenced and ana...

We discover new hereditary classes of graphs that are minimal (with respect to set inclusion) of unbounded clique-width. The new examples include split permutation graphs and bichain graphs. Each of these classes is characterised by a finite list of minimal forbidden induced subgraphs. These, therefore, disprove a conjecture due to Daligault, Rao and Thomassé from 2010 claiming that all such mi...

Microtubule-associated protein 1B (MAP1B) is a major constituent of the neuronal cytoskeleton that is expressed at high levels during early brain development and plays a role in axonal growth and neuronal plasticity. Previous studies suggested that the regulation of its gene expression is primarily at the transcriptional level. Thus, the characterization of the promoter region should help to de...

background: malassezia are dimorphic, lipid-dependent yeasts, which are responsible for causing several cutaneous and sys­temic conditions. although cyclophilins (cyps) are highly conserved cytosolic proteins that catalyze the peptidyl-prolyl cis-trans isomerazation reaction before protein folding process, it has been suggestive of an allergen in a few numbers of fungi such as aspergillus fumig...
