Authors: M.X. Vila Nova, L.R. Borges, A.C.B. de Sousa, B.T.R.V. Brasileiro, E.A.L.A. Lima, A.F. da Costa and N.T. de Oliveira
Onion anthracnose, caused by Colletotrichum gloeosporioides, is one of the main diseases of onions in the State of Pernambuco. We examined the pathogenicity of 15 C. gloeosporioides strains and analyzed their genetic variability using RAPDs and internal transcribed spacers (ITS) of the rDNA region. Ten of the strains were obta.. Read More»

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»

A small B chromosome in the grasshopper Ommexecha virens (Ommexechidae)
Authors: T.E. Souza, L.C. Silva-Neto, J.F. Santos, V. Loreto and T.T. Rieger
B chromosomes, also called supernumerary or accessory chromosomes, have been characterized as extra elements found in the karyotypes of different eukaryotic species. B chromosomes are nonvital and only occur in some individuals within a species. Moreover, the chromosomes contain silenced genes, and they exhibit heterochromatinization and the accumulation ..

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»

Genetic variability of ERCC1 and ERCC2 influences treatment outcomes in gastric cancer
Authors: W.H. Yu, Y.X. Wang, J.Q. Guo, Y.L. Wang, J.S. Zheng and K.X. Zhu
We performed a study to investigate the role of ERCC1 (rs11615, rs2298881, and rs3212986) and ERCC2 (rs13181, rs238406, and rs1799793) polymorphisms in the prognosis of gastric cancer. A total of 346 patients with gastric cancer were recruited between May 2009 and May 2012. Single nucleotide polymorphism genotyping was performed using the Sequenom MassARR.. Read More»

Quantitative assessment of protein function prediction programs
Authors: B.N. Rodrigues, M.B.R. Steffens, R.T. Raittz, I.C.R. Santos-Weiss and J.N. Marchaukoski
Fast prediction of protein function is essential for high-throughput sequencing analysis. Bioinformatic resources provide cheaper and faster techniques for function prediction and have helped to accelerate the process of protein sequence characterization. In this study, we assessed protein function prediction programs that accept amino acid sequences as i.. Read More»

Silencing effect of lentiviral vectors encoding shRNA of Herp on endoplasmic reticulum stress and inflammatory responses in RAW 264.7 macrophages
Authors: F.L. Chen, Q. Li, J.Y. Zhang1,, L.J. Lei, Z. Zhang, T.N. Mahmoud, X.G. Wang, P.F. Lin, Y.P. Jin and A.H. Wang
Herp, a mammalian protein with a ubiquitin-like domain, can be strongly upregulated by endoplasmic reticulum (ER) stress during ER-associated protein degradation. However, the other cellular functions of Herp remain unclear. We explored the effect of Herp on ER stress and inflammatory responses in RAW 264.7 macrophages that had been exposed to tunicamycin..

Association of regulator of G protein signaling (RGS5) gene variants and essential hypertension in Mongolian and Han populations
Authors: P.Y. Chang, L. Qin, P. Zhao and Z.Y. Liu
Genetic variants of the RGS5 gene are believed to be risk factors for hypertension and cardiovascular diseases. In this study, we investigated the association between RGS5 gene variants and hypertension in the Mongolian and Han populations. Peripheral blood was obtained from 429 unrelated Mongolian herdsmen and 416 Han farmers [including essential hyperte.. Read More»
