Genetic variation of Sargassum horneri populations detected by inter-simple sequence repeats
Authors: J.R. Ren, R. Yang, Y.Y. He and Q.H. Sun
The seaweed Sargassum horneri is an important brown alga in the marine environment, and it is an important raw material in the alginate industry. Unfortunately, the fixed resource that was originally reported is now reduced or disappeared, and increased floating populations have been reported in recent years. We sampled a floating population and 4 fixed c.. Read More»

Polymorphism of mitochondrial DNA in the Brazilian Canind�© goat breed
Authors: N.M.V. Silva, E.C. Pimenta Filho, J.K.G. Arandas, M.A. Gomes Filho, E. Ferreira, I. Del Cerro, C. Fonseca and M.N. Ribeiro
The success of the geographical distribution of goat populations around the world is a consequence of the adaptive potential of these breeds. Several relevant traits to the success of the species in colonizing different ecosystems (and use by man) evolved before domestication. These features were relevant for the selection of .. Read More»

In silico characterization of three two-component systems of Ehrlichia canis and evaluation of a natural plant-derived inhibitor
Authors: E.V. Santos G. Silva G.P. Cardozo T.A. Bitencourt S.C. Fran�§a A.L. Fachin M. Marins
Two-component signal transduction systems (TCS) are important elements in the interaction of endobacteria with host cells. They are basically composed of two proteins, an environmental signal sensor and a response regulator, which activate genes involved in a wide range of bacterial responses to their environment. We analyzed three sets of genes correspon.. Read More»

Genetic variability in Jatropha curcas L. from diallel crossing
Authors: D.O. Ribeiro, R. Silva-Mann, S.V. Alvares-Carvalho, E.M.S. Souza, M.C. Vasconcelos and A.F. Blank
Physic nut (Jatropha curcas L.) presents high oilseed yield and low production cost. However, technical-scientific knowledge on this crop is still limited. This study aimed to evaluate and estimate the genetic variability of hybrids obtained from dialell crossing. Genetic variability was carried out using ISSR molecular marker.. Read More»

Association of RUNX2 and TNFSF11 genes with production traits in a paternal broiler line
Authors: N.V. Grupioni, N.B. Stafuzza, A.B. Carvajal, A.M.G. Ibelli, J.O. Peixoto, M.C. Ledur, D.P. Munari
Intense selection for production traits has improved the genetic gain of important economic traits. However, selection for performance and carcass traits has led to the onset of locomotors problems and decreasing bone strength in broilers. Thus, genes associated with bone integrity traits have become candidates for genetic stu.. Read More»

Molecular characterization of the pathogenic plant fungus Rhizoctonia solani (Ceratobasidiaceae) isolated from Egypt based on protein and PCR-RAPD profiles
Authors: M.A. Mahmoud S.A. Al-Sohaibani A.M.M. Abdelbacki M.R. Al-Othman A.R.M. Abd El- Aziz K.K. Kasem M.S. Mikhail K.K. Sabet M.R. Omar E.M. Hussein
Twenty-one isolates of Rhizoctonia solani were categorized into three anastomosis groups consisting of AG-4-HG-I (eight isolates), AG-2-2 (nine isolates) and AG-5 (four isolates). Their pathogenic capacities were tested on cotton cultivar Giza 86. Pre-emergence damping-off varied in response to the different isolates; however, the differences were not signif.. Read More»

Serum miR-200c expression level as a prognostic biomarker for gastric cancer
Authors: H.-P. Zhang,F.-B. Sun, S.-J. Li
The aim of the present study was to analyze the serum expression level of microRNA-200c (miR-200c) in gastric cancer (GC) patients and to determine the relationship between this expression and clinicopathological features and survival. Serum samples were obtained from 98 patients with GC between February 2008 and January 2013... Read More»

Identification of 19 loci for reproductive traits in a local Chinese chicken by genome-wide study
Authors: Q.C. Fan, P.F. Wu, G.J. Dai, G.X. Zhang, T. Zhang, Q. Xue,H.Q. Shi, J.Y. Wang
Reproductive traits have long been studied and have an important influence on chicken breeding. To identify quantitative trait loci affecting reproductive traits, a genome-wide analysis of a Chinese chicken breed was performed to analyze age at first egg body weight at first egg, first egg weight, egg weight at the age of 300 ..

Spittle protein profile of Mahanarva spectabilis (Hemiptera: Cercopidae) fed various elephant grass genotypes
Authors: A.M. Auad M.F. Martins I. Fonseca S.V. Paula-Moraes M.M. Kopp M.C. Cordeiro
An understanding of the interaction between spittlebugs and forage grasses is essential for establishing factors that favor productive pastures. In the present study, we evaluated the protein profiles of the spittle of Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae) fed various elephant grass genotypes. Each plant was infested with a single fif.. Read More»
