Authors: V. Specian, A.T. Costa, A.C. Felber, J.C. Polonio, J.L. Azevedo and J.A. Pamphile
Acerola (Malpighia emarginata) is a shrub native to tropical and subtropical climates, which has great commercial interest due to the high vitamin C content of its fruit. However, there are no reports of the endophytic community of this plant species. The aim of this study was to verify the genetic diversity of the leaf endoph.. Read More»

Virulence and genetic diversity among isolates of Mycosphaerella fijiensis in two regions of Brazil
Authors: G.F. Silva, V.S. Santos, N.R. Sousa, R.E. Hanada and L. Gasparotto
Black sigatoka, caused by the fungus Mycosphaerella fijiensis (anamorphic stage: Paracercospora fijiensis), was first detected in Brazil in early 1998 in the Benjamin Constant and Tabatinga municipalities in the State of Amazonas, near to where the borders of Brazil, Colombia, and Peru converge. Understanding how cultivars rea.. Read More»

Association of APOA1 gene polymorphisms (rs670, rs5069, and rs2070665) with dyslipidemia in the Kazakhs of Xinjiang
Authors: D.W. Feng, R.L. Ma, H. Guo, J. He, Y.Z. Yan, Muratbek, Q. Niu,S.G. Li, D.S. Rui, F. Sun, M. Zhang, J.Y. Zhang, Y.S. Ding, J.M. Liu, K. Wang and S.X. Guo
The aim of this study was to investigate the potential association between apolipoprotein A1 (APOA1) gene rs670, rs5069, and rs2070665 polymorphisms and dyslipidemia in the Kazakh population of Xinjiang, China. Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) was used to identify APOA.. Read More»

Mitotic crossing-over induced by two commercial herbicides in diploid strains of the fungus Aspergillus nidulans
Authors: R.A. Cardoso, L.T.A. Pires, T.D. Zucchi, F.D. Zucchi and T.M.A.D. Zucchi
Some herbicides are suspected of promoting teratogenic, carcinogenic and mutagenic events. Detection of induced mitotic crossing-over has proven to be an indirect way of testing the carcinogenic properties of suspicious substances, because mitotic crossing-over is involved in the multistep process of carcinogenesis. We examine.. Read More»

VP6 gene diversity in Brazilian strains of porcine group C rotavirus
Authors: K.C. M�©dici, A.F. Barry, A.F. Alfieri and A.A. Alfieri
Group C rotavirus (RV-C) has been found in Brazilian pig herds; however, wild-type strains have not yet been characterized. We made a molecular analysis of a region of gene 5 in Brazilian RV-C strains. Stool samples from 11 piglets (diarrheic and with normal consistency) positive for the RV-C VP6 gene in an RT-PCR assay were s.. Read More»

Antibacterial activity of leaf extract of Breonadia salicina (Rubiaceae), an endangered medicinal plant of Saudi Arabia
Authors: F. Al-Qurainy, Abdel-Rhman Z. Gaafar, S. Khan, M. Nadeem, M. Tarroum, A. Alaklabi and J. Thomas
Wild plants can contain bioactive compounds with potential activity against disease-causing microorganisms. In the Kingdom of Saudi Arabia, there are many plant species that may have antibacterial, antifungal, or antiviral activities, among other properties. We extracted bioactive compounds with methanol as well as with water from leaves of Breonadia sali.. Read More»

Molecular evolution of the melanocortin 1-receptor pigmentation gene in rodents
Authors: G.L. Gon�§alves, V.R. Paix�£o-C�´rtes and T.R.O. Freitas
Adaptive variation in the melanocortin 1-receptor gene (MC1R), a key locus in melanogenesis, has been identified in some species of rodents. However, in others, MC1R has no causative role in pigmentation phenotypes despite their coat color variation. In this study, we characterized the rates and patterns of MC1R nucleotide and amino acid sequence evolutio.. Read More»

Complete mitochondrial genomes reveal phylogeny relationship and evolutionary history of the family Felidae
Authors: W.Q. Zhang and M.H. Zhang
Many mitochondrial DNA sequences are used to estimate phylogenetic relationships among animal taxa and perform molecular phylogenetic evolution analysis. With the continuous development of sequencing technology, numerous mitochondrial sequences have been released in public databases, especially complete mitochondrial DNA sequences. Using multiple sequence.. Read More»

Construction of recombinant adenoviruses carrying the optimal shRNA template against goat PTHrP and successful suppression of PTHrP expression in mammary epithelial cells
Authors: H.L. Zheng, X.M. Liu, Q. Yu, R.F. Xing, Z.Y. Yang and J. Luo
Parathyroid hormone-related protein (PTHrP) is a protein member of the parathyroid hormone family that regulates the dynamic balance between blood and bone calcium during lactation. However, the mechanism of its regulation is not very clear. In order to establish a framework for further functional studies of the PTHrP gene in goat mammary gland epithelial.. Read More»
