The white wax insect Ericerus pela Chavannes (Hemiptera: Coccoidea) is an economically valuable insect species that has been used for over a thousand years in China. The present study focuses on assessing the genetic variability in different populations of E. pela collected from seven Chinese provinces. The amplified fragment length polymorphism technique..

Previous molecular genetic studies of the goat hair life cycle have focused primarily on a limited number of genes and proteins. To identify additional genes that may play important roles in hair follicle cycle regulation, Illumina sequencing technology was used to catalog differential gene expression profiles in the hair growth cycle (anagen to catagen) ..

Currently, the market demands products committed to protecting human health and the environment, known as clean products. We developed a protocol using DNA fragments containing only the gene sequence of interest, to replace the circular vectors containing genes for antibiotic resistance and other undesirable sequences, for obt..

Little is known about the classification and phylogenetic relationships of the leaf monkeys (Presbytis). We analyzed mitochondrial DNA sequences of cytochrome b (Cyt b) and 12S rRNA to determine the phylogenetic relationships of the genus Presbytis. Gene fragments of 388 and 371 bp of Cyt b and 12S rRNA, respectively, were seq.. Read More»

Brazil has only one public genetic pool of Bombyx mori strains, which was established in 2005 at Universidade Estadual de Maringá, Maringá, Paraná State. This genetic bank has been maintained, and the strains have been characterized using genetic and morphological tools. The quantitative and qualitative traits, directly or indirectly .. Read More»

We analyzed 20 exons, with their intron-exon boundaries, of the bovine Flt-1 gene, using a strategy combining PCR amplification and single-strand conformational polymorphism analysis (PCR-SSCP), followed by nucleotide sequence analysis, in 675 cattle. We then looked for associations between polymorphisms and growth traits. Twe.. Read More»

Caspases (CASP) are intracellular proteases that play roles as mediators of apoptosis. Activation of caspase 3 is enhanced in chronic periodontitis. Thus, we hypothesized that single nucleotide polymorphisms (SNPs) of CASP genes might be associated with this condition in the Korean population. To investigate whether such polymorphisms might be involved in.. Read More»

Placusa pinearum, a newly described beetle species found living in pine shoot tunnels bored by the pine tip moth, Dioryctria rubella (Pyralidae), has potential as a vector to transport biological agents for controlling this moth pest of pine trees because of the high degree of niche overlap (co-occurrence) between them. In order to help determine the suit.. Read More»

Genetic regulatory networks are the key to understanding biochemical systems. One condition of the genetic regulatory network under different living environments can be modeled as a synchronous Boolean network. The attractors of these Boolean networks will help biologists to identify determinant and stable factors. Existing methods identify attractors bas.. Read More»

We compared and analyzed expression of the BPI gene of Sutai piglets ranging from newborn to post-weaning days 8, 18, 30, and 35 by the real-time PCR method, in order to determine if it is involved in protection against disease caused by ETEC F18. There was a significant difference between 18- and 35-day expression in the jejunum. There were also signific.. Read More»
