Differentiation between Triatoma arthurneivai and Triatoma wygodzinskyi (Hemiptera: Reduviidae: Triatominae) using cytotaxonomy
Authors: K.C.C. Alevi, C.H.L. Imperador, F.F.F. Moreira, J. Jurberg and M.T.V. Azeredo-Oliveira
Using classic morphometric techniques to examine the head and thorax of Triatoma specimens, researchers identified a possible taxonomic problem involving T. arthurneivai (Lent & Martins) and T. wygodzinskyi (Lent). A recent geometric morphometric study indicated that the insects captured outside the Serra do Cipó re.. Read More»

Endophytic and pathogenic isolates of the cacao fungal pathogen Moniliophthora perniciosa (Tricholomataceae) are indistinguishable based on genetic and physiological analysis
Authors: T.G. Lana, J.L. Azevedo, A.W.V. Pomella, R.T.R. Monteiro, C.B. Silva and W.L. Ara�ºjo
We evaluated the genetic and physiological variability of Moniliophthora perniciosa obtained from healthy and diseased branches of cacao (Theobroma cacao) plants. The diversity of the isolates was evaluated by RAPD technique and by studies of virulence and exoenzyme production. The genetic variability of endophytic and pathogenic M. perniciosa was evaluat..

Differential gene expression patterns in the autogamous plant Hordeum euclaston (Poaceae)
Authors: J.E. Georg-Kraemer, C.A.S. Ferreira and S.S. Cavalli
Sib-seedlings of 95 strains of the strictly autogamous grass Hordeum euclaston were analyzed by horizontal polyacrylamide gel electrophoresis for four isoenzyme systems at a specific ontogenetic stage. We found differences in the activity of some genes among individuals of this species. Hence, an ontogenetic analysis was carri.. Read More»

Population genetic structure of the migratory rice leaf roller, Cnaphalocrocis medinalis (Lepidoptera: Pyralidae), inferred from the mitochondrial A+T-rich region and nuclear ITS2 sequences
Authors: X. Wan, J. Li, M.J. Kim, T.H. Kang, B.R. Jin and I. Kim
The population genetics of the migratory rice leaf roller, Cnaphalocrocis medinalis (Lepidoptera: Pyralidae), was characterized using the maternally inherited mitochondrial A+T-rich region and bi-parentally inherited nuclear internal transcribed spacer 2 (ITS2). One hundred and eighty-seven specimens of the rice leaf roller co.. Read More»

Large-scale tissue-specific and temporal gene expression profiles in Pengze crucian carp
Authors: Y. Zheng, J.Z. Chen, H.P. Wang, M. Li, H.W. Liang, X.W. Bing and Z.Z. Wang
In the present study, the tissue-specific and temporal gene expression profiles of four catalogues of gonadal development-related genes (sex differentiation-related, steroid receptor, steroidogenic, and structural genes) were detected in nine tissues and during 11 successive developmental stages in the Pengze crucian carp (Pcc..

Genetic diversity of Vriesea cacuminis (Bromeliaceae): an endangered and endemic Brazilian species
Authors: P.C.C. Ribeiro, L.C. Pinheiro, R. Domingues, R.C. Forzza, M.A. Machado and L.F. Viccini
Data about the genetic structure can help to understand the evolutionary process of natural populations as well as to drive strategies of conservation. Vriesea cacuminis, an endemic Brazilian Bromeliad, has been found in 2 areas of Minas Gerais State. One is a legal preservation unit (Ibitipoca State Park) and the other an unprotected area (Serra Negra). .. Read More»

Isolation and characterization of 12 polymorphic microsatellite markers for the frog Pelophylax hubeiensis
Authors: J.-C. Yan, F.-H. Zhu and H.-L. Wu
Twelve polymorphic microsatellite loci were isolated from an (AC)n- and (AG)n-enriched DNA library for the endemic Chinese frog Pelophylax hubeiensis (Ranidae). The number of alleles per locus ranged from two to eight, with a mean of 5.17. The observed and expected heterozygosities ranged from 0.226 to 0.839 and from 0.204 to .. Read More»

Molecular characterization and phylogenetic analysis of porcine epidemic diarrhea virus samples obtained from farms in Gansu, China
Authors: M.Z. Huang, H. Wang S.Y. Wang, D.A. Cui, X. Tuo and Y.M. Liu
Porcine epidemic diarrhea poses significant sanitation problems in the porcine industry, and has negatively affected the economy in recent years. In this study, 48 fecal specimens were collected from piglets from four intensive swine farms located in the Gansu Province of China. The molecular diversity and phylogenetic relatio.. Read More»

Meta-analysis demonstrates lack of a relationship between XRCC1-399 gene polymorphisms and susceptibility to hepatocellular carcinoma
Authors: X.Y. Zeng, J.M. Huang, J.W. Xu, Y. Xu, H.P. Yu, L. Ji and X.Q. Qiu1,
XRCC1-399 allele polymorphisms have been reported to be associated with susceptibility to hepatocellular carcinoma (HCC), but the conclusions of the various studies have been inconsistent. We conducted a meta-analysis of available studies to determine whether XRCC1-399 alleles influence susceptibility to hepatocellular carcinoma. We searched English-langu.. Read More»

Phenotypic characteristics for discrimination between advanced genotypes of Brachiaria ruziziensis
Authors: B.A. Rezende, C.B. Ribeiro, D.H.L. Teixeira, F.M.A. Gon�§alves and F. Souza Sobrinho
The aim of this study was to use multivariate methods and Pearson and partial correlations to disregard phenotypic characteristics that contribute little to differentiation between Brachiaria ruziziensis genotypes. Eighty-one genotypes of B. ruziziensis were assessed in completely randomized blocks with three replications. Ten phenotypic characteristics w.. Read More»
