Authors: Y.J. Fan, T. Grebenc, J. Wei, Y.L. Zhao, W. Yan and L.B. Wang
We investigated the diversity of ectomycorrhiza associated with the endemic Picea crassifolia in Mount Helan National Nature Reserve in Inner Mongolia, China. Toward this objective, we conducted morphological and molecular identification of ectomycorrhizae in soil cubes taken from pure P. crassifolia stands. Eleven types of ec.. Read More»

Construction and analysis of a subtractive cDNA library of early embryonic development in duck
Authors: Y.L. Liu, L.X. Zhong, J.J. Li, J.D. Shen, D.Q. Wang, Z.R. Tao, F.X. Shi and L.Z. Lu
Several studies have documented the process of early embryonic development in poultry; however, the molecular mechanisms underlying its developmental regulation are poorly understood, particularly in ducks. In this study, we analyzed differential gene expression of embryos 6 and 25 h following oviposition to determine which genes regulate the early develo.. Read More»

Role of ADH2 and ALDH2 gene polymorphisms in the development of Parkinson�s disease in a Chinese population
Authors: C.C. Zhao, H.B. Cai, H. Wang and S.Y. Pan
In this study, we investigated the role of ADH2 Arg47His and ALDH2 Glu487Lys genetic polymorphisms in the development of Parkinson’s disease in a Chinese population. Between January 2013 and May 2014, 115 patients with Parkinson’s disease and 214 healthy controls were recruited in our study. Genotyping of ADH2 Arg4.. Read More»

Effect of organic matter enrichment on the fungal community in limestone cave sediments
Authors: E.L.S. Marques, J.C.T. Dias, G.S. Silva, C.P. Pirovani and R.P. Rezende
Caves are considered major touristic attractions. The management plans of many such caves include limiting the number of visitors; however, the human impact on microbial communities within caves is rarely considered. Therefore, the aim of this study was to evaluate the impact of human-transferred organic matter on the fungal m.. Read More»

Isolation and characterization of new polymorphic microsatellite markers from the cuttlefish Sepiella maindroni (Cephalopoda; Sepiidae)
Authors: B.-Y. Guo, P.Z. Qi, A.Y. Zhu, Z.M. Lv, W.C. Wang and C.W. Wu
Fifteen new polymorphic microsatellite loci were developed for the cuttlefish Sepiella maindroni. In 32 individuals from a wild population of coastal Ningde, Fujian Province, China, the number of alleles at these loci varied between 2 and 12, with an average of 5.86. The mean observed and expected heterozygosities were 0.6917 and 0.5993, respectively. Amo.. Read More»

Association between VEGF and eNOS gene polymorphisms and lumbar disc degeneration in a young Korean population
Authors: I.B. Han, A.E. Ropper, Y.D. Teng, D.A. Shin, Y.J. Jeon, H.M. Park, D.E. Shin, Y.S. Park, K.N. Kim and N.-K. Kim
Disturbances in blood flow to intervertebral discs (IVD) play an important role in IVD degeneration. Vascular endothelial growth factor (VEGF) and endothelial nitric oxide synthase (eNOS) are extremely important angiogenic factors for vasodilation and neovascularization. We investigated the relationship between single nucleotide polymorphisms (SNPs) of th.. Read More»

Recycling of superfine resolution agarose gel
Authors: T.-Y. Seng, R. Singh, Q.Z. Faridah, S.-G. Tan and S.S.R.S. Alwee
Genetic markers are now routinely used in a wide range of applications, from forensic DNA analysis to marker-assisted plant and animal breeding. The usual practice in such work is to extract the DNA, prime the markers of interest, and sift them out by electrically driving them through an appropriate matrix, usually a gel. The gels, made from polyacrylamid.. Read More»

Characterization and description of a multiple sex chromosome system in Potamotrygon motoro (Chondrichthyes, Myliobatiformes) from the Paran�¡ River, Argentina
Authors: D.R. Aichino, M.C. Pastori, H.A. Roncati, M.A. Ledesma, A.C. Swar�§a and A.S. Fenocchio
The Potamotrygonidae family represents the only freshwater group of specialized elasmobranchs and is composed of 4 genera: Plesiotrygon, Paratrygon, Potamotrygon, and Heliotrygon. Individuals of Potamotrygon motoro were collected from the Paraná River at Ituzaingó (Province of Corrientes) in Argentina. Mitotic preparations were obtained usin.. Read More»

Genetic diversity and selection gain in the physic nut (Jatropha curcas)
Authors: B.P. Brasileiro, S.A. Silva, D.R. Souza, P.A. Santos, R.S. Oliveira and D.H. Lyra
The use of efficient breeding methods depends on knowledge of genetic control of traits to be improved. We estimated genetic parameters, selection gain, and genetic diversity in physic nut half-sib families, in order to provide information for breeding programs of this important biofuel species. The progeny test included 20 half-sib families in 4 blocks a.. Read More»

RNA interference-mediated silencing of the starch branching enzyme gene improves amylose content in rice
Authors: H.Y. Jiang, J. Zhang, J.M. Wang, M. Xia, S.W. Zhu and B.J. Cheng
Amylose and amylopectin are the 2 major components of plant storage starch. The rice starch branching enzyme (RBE) plays an important role in the starch components of rice. In the present study, we selected a specific 195-bp segment from the RBE3 gene to construct hairpin DNA, which was driven by an endosperm-specific high molecular weight glutenin promot.. Read More»
