A new repertoire of informations about the quorum sensing system in Salmonella enterica serovar Enteritidis PT4
Authors: M.E.M. Campos-Galv�£o,T.D.S. Leite,A.O.B. Ribon,E.F. Ara�ºjo and M.C.D. Vanetti
Salmonella spp are among the main causative agents of foodborne diseases. Some phenotypes associated with increased drug resistance and virulence are regulated by quorum sensing (QS). In the present study, the autoinducer (AI)-1- and -2-mediated QS mechanisms were characterized in Salmonella enterica serovar Enteritidis PT4 for the first time. Salmonella .. Read More»

Correspondence between performance of Eucalyptus spp trees selected from family and clonal tests
Authors: C.A.F. Reis, F.M.A. Gon�§alves, L.N. Rosse, R.R.G.F. Costa and M.A.P. Ramalho
We examined the correspondence in performance between trees selected from a family test and their respective clones from a clonal test of Eucalyptus. Full-sib families were obtained from controlled pollination among individuals of Eucalyptus grandis and between E. grandis and E. urophylla. The hybridizations did not follow a f.. Read More»

3'-UTR polymorphism (rs10434) in the VEGF gene is associated with B-CLL in a Chinese population
Authors: L.X. Zhu,X.J. Ye,Y.G. Wang,J.J. Zhu, W.Z. Xie,Y.M. Zhao and X.Y. Lai
We investigated the relationship between a VEGF genetic polymorphism and B cell chronic lymphocytic leukemia (B-CLL). A total of 102 patients with B-CLL and 124 healthy subjects were included in this study. All individuals were typed for the rs10434 in the vascular endothelial growth factor (VEGF) gene using the TaqMan technique. We found that the A allel.. Read More»

Descriptor selection for banana accessions based on univariate and multivariate analysis
Authors: L.P. Brand�£o, C.P.F. Souza, V.M. Pereira, S.O. Silva, J.A. Santos-Serejo, C.A.S. Ledo and E.P. Amorim
Our objective was to establish a minimum number of morphological descriptors for the characterization of banana germplasm and evaluate the efficiency of removal of redundant characters, based on univariate and multivariate statistical analyses. Phenotypic characterization was made of 77 accessions from Bahia, Brazil, using 92 descriptors. The selection of.. Read More»

Sequence characterization, polymorphism, and tissue expression profile of an effector immediate-early gene: activity-regulated cytoskeletal associated protein gene (Arc/Arg3.1) in swamp and river buffalo
Authors: F. Yuan, J.L. Huo1, D.L. Li, Y.Y. Yuan, W.Z. Lu, S. Song, L.J. Li and Y.W. Miao
The activity-regulated cytoskeletal associated protein (Arc/Arg3.1) has been implicated in experience-dependent synaptic plasticity and memory formation. However, information regarding its coding gene in buffalo remains scarce. In this study, the full-length of Arc/Arg3.1 was isolated and characterized (accession No. JX491649).. Read More»

Single nucleotide polymorphism analysis of the endopolygalacturonase gene in peach and its potential use in crossbreeding programs
Authors: Y. Jiao,R. Ma and M. Yu
Single nucleotide polymorphisms (SNPs) are the most abundant sequence variations found in plant genomes and are widely used as molecular genetic markers in genetic diversity studies and crossbreeding programs. In this study, we examined 113 DNA sequences of the endopolygalacturonase (endo-PG) gene from 67 peach accessions and found a total of 56 SNPs and .. Read More»

Genetic differentiation in Aspidosperma polyneuron (Apocynaceae) over a short geographic distance as assessed by AFLP markers
Authors: J.O. Damasceno, E.A. Ruas, L.A. Rodrigues, C.F. Ruas, E. Bianchini, J.A. Pimenta3 and P.M. Ruas
Studies on intraspecific variation can contribute to the development of conservation strategies by identifying units of conservation for threatened species. Aspidosperma polyneuron is a tropical tree of seasonal semideciduous forests that is currently endangered and protected because it has been heavily logged for lumber, alth.. Read More»

Comparative in vitro and in planta analyses of extracellular enzymes secreted by the pathogenic fungus Sclerotinia sclerotiorum
Authors: M.B. Oliveira, S.C. Barbosa and S. Petrofeza
Dry bean (Phaseolus vulgaris L.) is an important economic crop in Brazil but its yield can be significantly reduced by white mold, a disease caused by Sclerotinia sclerotiorum (Lib.) de Bary, a necrotrophic, highly destructive, and non-host-specific fungus. This fungus secretes numerous cell wall-degrading enzymes such as polygalacturonases, exo-β-1,.. Read More»

Transferability of retrotransposon primers derived from Persimmon (Diospyros kaki Thunb.) across other plant species
Authors: X.Y. Du, Q.N. Hu, Q.L. Zhang, Y.B. Wang and Z.R. Luo
Retrotransposon-based molecular markers are powerful molecular tools. However, these markers are not readily available due to the difficulty in obtaining species-specific retrotransposon primers. Although recent techniques enabling the rapid isolation of retrotransposon sequences have facilitated primer development, this process nonetheless remains time-c.. Read More»
