Diversity and genetic structure among subpopulations of Gossypium mustelinum (Malvaceae)
Authors: M.F. Alves P.A.V. Barroso A.Y. Ciampi L.V. Hoffmann V.C.R. Azevedo U. Cavalcante
Gossypium mustelinum is the only cotton species native to Brazil; it is endemic to the semi-arid region of the northeast. The populations are found near perennial and semi-perennial sources of water, such as ponds or pools in intermittent streams. Problems with in situ conservation derive from human interference in its habitat, mainly because of excessive.. Read More»

Analysis of the genetic diversity of Lonicera japonica Thumb. using inter-simple sequence repeat markers
Authors: H.Y. He, D. Zhang, H. Qing and Y. Yang
Inter-simple sequence repeats (ISSRs) were used to analyze the genetic diversity of 21 accessions obtained from four provinces in China, Shandong, Henan, Hebei, and Sichuan. A total of 272 scored bands were generated using the eight primers previously screened across 21 accessions, of which 267 were polymorphic (98.16%). Genet.. Read More»

Characterization of chicken natural resistance-associated macrophage protein encoding genes (Nramp1 and Nramp2) and association with salmonellosis resistance
Authors: X.M. He M.X. Fang Z.T. Zhang Y.S. Hu X.Z. Jia D.L. He S.D. Liang Q.H. Nie X.Q. Zhang
Natural resistance-associated macrophage protein 1 and 2 encoding genes (Nramp1 and Nramp2) are related to many diseases. We cloned the cDNA of chicken Nramp1 and Nramp2 genes, characterized their expression and polymorphisms, and investigated the association of some SNPs with resistance to salmonellosis. The Nramp1 cDNA was 1746 bp long and the Nramp2 cD.. Read More»

Transfer and expression of the rabbit defensin NP-1 gene in lettuce (Lactuca sativa)
Authors: D. Song, X. Xiong, W.F. Tu, W. Yao, H.W. Liang, F.J. Chen and Z.Q. He
Lettuce (Lactuca sativa L.) is an annual plant of the daisy family, Asteraceae, with high food and medicinal value. However, the crop is susceptible to several viruses that are transmitted by aphids and is highly vulnerable to post-harvest diseases, as well as insect and mammal pests and fungal and bacterial diseases. Here, th.. Read More»

Diversity, population structure, and evolution of local peach cultivars in China identified by simple sequence repeats
Authors: Z.J. Shen, R.J. Ma, Z.X. Cai, M.L. Yu and Z. Zhang
The fruit peach originated in China and has a history of domestication of more than 4000 years. Numerous local cultivars were selected during the long course of cultivation, and a great morphological diversity exists. To study the diversity and genetic background of local peach cultivars in China, a set of 158 accessions from different ecological regions,.. Read More»

Association of liver X receptor �± (LXR�±) gene polymorphism and ischemic stroke
Authors: H.X. Wang, K. Zhang, L. Zhao, J.W. Tang, L.Y. Gao and Z.P. Wei
We examined the relationship between the liver X receptor a gene (LXRα) rsl2221497 polymorphism and the susceptibility to ischemic stroke in a Chinese population. The polymerase chain reaction-restriction fragment length polymorphism technique was used to detect the genotype of rsl2221497 in the LXRαgene of 300 stroke patients and 300 healthy .. Read More»

Characterization of SNPs in strawberry cultivars in China
Authors: A.J. Ge J. Han X.D. Li M.Z. Zhao H. Liu Q.H. Dong J.G. Fang
Single nucleotide polymorphisms (SNPs) occur at high frequencies in both plant and animal genomes and can provide broad genome coverage and reliable estimates of genetic relationships. The availability of expressed sequence tag (EST) data has made it feasible to discover SNPs. DNA analysis is crucial in genetic studies not only for strawberry breeding progra.. Read More»

Molecular analysis and frequency of Staphylococcus aureus virulence genes isolated from bloodstream infections in a teaching hospital in Tianjin, China
Authors: L.X. Wang Z.D. Hu Y.M. Hu B. Tian Jing Li F.X. Wang H. Yang H.R. Xu Y.C. Li J. Li
Staphylococcus aureus is an important cause of bloodstream infections worldwide. We examined the prevalence of genes that encode erythromycin ribosome methylase and bacterial toxins in S. aureus collected from bloodstream infections. Sixty different S. aureus isolates were obtained from blood cultures of patients who were admitted to a Teaching Hospital i.. Read More»

Involvement of ERK1/2 signaling in proliferation of eight liver cell types during hepatic regeneration in rats
Authors: X.G. Chen C.S. Xu Y.M. Liu
It has been well established that ERK1/2 signaling, often subdivided into nine types of pathways, can regulate the hepatocyte proliferative response during liver regeneration. However, the effect of ERK1/2 signaling on the proliferation of other hepatic cell types remains unclear. We isolated and purified 8 liver cell types at 10 time points after 2/3 hep.. Read More»
