Fusarium circinatum causes pine pitch canker (PPC) disease and associated symptoms such as resinous lesions, mechanical weakness, crown dieback that may lead to mortality in Pinus Pseudotsuga spp. There are no ameliorative techniques available for the disease, genetic resistance among populations support commercial plantation deployment has not been well characterized. In this study, we charact...
This study examined the effect of (E)-2-methyl-6-(2-phenylethynyl)-pyridine (SIB-1893), a selective non-competitive metabotropic glutamate subtype 5 receptor (mGluR5) antagonist, on body temperature in freely moving Wistar rats. Temperature was monitored using programmed microchips, implanted subcutaneously in rats, at several times: 0, 5, 10, 20, 30, 45, 60, 90, 120 and 180 min after intraperi...
BACKGROUND AND OBJECTIVE Oesophageal cancer is one of the most common and deadliest cancers worldwide. Our previous population-based study reported a high prevalence of oesophageal cancer in Chaoshan, Guangdong Province, China. Ancestors of the Chaoshan population migrated from the Taihang Mountain region of north-central China, which is another high-incidence area for oesophageal cancer. The p...
Estimation of the heritability for a given phenotype would provide basic information potential breeding programs. As one most precious common carp strains, Yellow River was subject to selection fast growth and slender body meet market demands. In present study, heritabilities shape (body length, BL height, BH) weight (BW) were estimated based on molecular parentage assignment 750 progenies from...
We performed global RNA transcript analysis and comprehensive gene group analysis of peripheral blood leukocyte (PBL) RNA from two groups of matched sib-pairs that were discordant for either schizophrenia (n = 33 sib-pairs) or bipolar disorder (n = 5 sib-pairs). The pairs chosen for these analyses were selected from families with known patterns of genetic linkage (5q for schizophrenia and 6q fo...
Understanding the genetic architecture of traits in breeding programs can be critical for making genetic progress. Important factors include the number of loci controlling a trait, allele frequencies at those loci, and allele effects in breeding germplasm. To this end, multiparental populations offer many advantages for quantitative trait locus (QTL) analyses compared to biparental populations....
The multidisciplinary project “MOREST” aims to improve our understanding of causes of summer mortality in Crassostrea gigas juveniles in France and to reduce its impact on oyster production. As part of the MOREST project, 43 full-sib families nested within 17 half-sib families were produced, planted out and tested in 3 sites during summer 2001 to assess to what extent genetic variability exists...
Insects exposed to genetically modified crops expressing Bacillus thuringiensis (Bt) toxins are under intense selection pressure that could result on widespread Bt resistance. Screening for early indications of Bt resistance developing in targeted Lepidoptera is conducted in many of the regions where genetically modified cotton and corn have been commercialized. Heliothis virescens (F.) (Lepido...
