Characterization of Gibberella fujikuroi complex isolates by fumonisin B-1 and B-2 analysis and by RAPD and restriction analysis of PCR-amplified int…

2000

Summary Twenty nine isolates of Fusarium spp. (twenty four of them belonging to the Gibberella fujikuroi complex) isolated from banana and corn from different geographical regions were analyzed for their ability to produce fumonisins B 1 and B 2 and for genetic relatedness using random amplified polymorphic DNA (RAPD) and restriction analysis of PCR amplification products of the 5.8s ribosomal DNA-intervening internal transcribed spacer regions (ITS I-5.8S-ITS II). For RAPD analysis, six of twenty oligonucleotide primers were selected after testing with five Fusarium spp. isolates and used to characterize 24 additional isolates. DNA fragments from the 29 isolates of Fusarium spp., which wer…

Yeast ecology of vineyards within Marsala wine area (western Sicily) in two consecutive vintages and selection of autochthonous Saccharomyces cerevis…

2012

In this work, the yeast ecology associated with the spontaneous fermentation of Grillo cultivar grapes from 10 vineyards was analyzed from grape harvest till complete consumption of must sugars. The microbiological investigation started with the plate count onto two culture media to distinguish total yeasts (TY) and presumptive Saccharomyces (PS). Yeasts were randomly isolated and identified by a combined genotypic approach consisting of restriction fragment length polymorphism (RFLP) of 5.8S rRNA gene and 26S rRNA and sequencing of D1/D2 domain of the 26S rRNA gene, which resulted in the recognition of 14 species belonging to 10 genera. The distribution of the yeasts within the vineyards s…

Typing of anastomosis groups of Rhizoctonia solani by restriction analysis of ribosomal DNA.

2003

A method based on restriction analysis of polymerase chain reaction (PCR)-amplified ribosomal DNA was developed for the rapid characterization of large populations of Rhizoctonia solani at the anastomosis group (AG) level. The restriction maps of the internal transcribed spacers (ITS) sequences were compared for 219 isolates of R. solani belonging to AG-1 to AG-12 and AG-BI, representing diverse geographic and host range origins. Four discriminant restriction enzymes (MseI, AvaII, HincII, and MunI) resolved 40 restriction fragment length polymorphism (RFLP) types among the 219 ITS sequences of R. solani. Each RFLP type could be assigned to a single AG except for two RFLP types, which were c…

C4 DNA RFLP reference typing report.

1990

One hundred and three individual DNA samples (including 23 families) were studied at the gene level during the reference typing of the fourth component of human complement at the VIth Complement Genetics Workshop in Mainz (1989). All samples were analyzed with the restriction enzyme Taq I and with two DNA probes recognizing the 5' ends of both C4 genes and the two adjacent 21-hydroxylase genes. This RFLP is informative for the number of C4 genes as well as for their respective gene size. We found a high degree of variation regarding the number of C4 genes, i.e. haplotypes with 1-3 structural C4 genes of 16 or 22 kb size. By correlating these haplotypes to the complotypes obtained by protein…

IL-6 -174G/C polymorphism and IL-6 serum levels in patients with liver cirrhosis and hepatocellular carcinoma.

2011

Recently, a link between high levels of circulating IL-6 and hepatocellular carcinoma (HCC) has been proposed. In addition, single nucleotide polymorphisms (SNPs) in the promoter region of the IL-6 gene have been reported to be related to several inflammatory-related conditions, including cancer. The purpose of this article is: (1) to evaluate the frequencies of SNPs in the IL-6 promoter region at position -174 and IL-6 serum levels in a group of patients with HCC and underlying liver cirrhosis (LC), and compare them with a group of LC patients without HCC; (2) to determine whether a possible correlation exists between the allelic variations, IL-6 serum levels, and the risk of developing HC…

Successive Invasion-Mediated Interspecific Hybridizations and Population Structure in the Endangered Cichlid Oreochromis mossambicus.

2013

Hybridization between invasive and native species accounts among the major and pernicious threats to biodiversity. The Mozambique tilapia Oreochromis mossambicus, a widely used freshwater aquaculture species, is especially imperiled by this phenomenon since it is recognized by the IUCN as an endangered taxon due to genetic admixture with O. niloticus an invasive congeneric species. The Lower Limpopo and the intermittent Changane River (Mozambique) drain large wetlands of potentially great importance for conservation of O. mossambicus, but their populations have remained unstudied until today. Therefore we aimed (1) to estimate the autochthonous diversity and population structure among genet…

Cluster of cases of Salmonella enterica serotype Rissen infection in a general hospital, Italy, 2007.

2009

In 2007, three strains of Salmonella enterica serotype Rissen (S. Rissen) were isolated in the laboratory of diagnostic microbiology of the General Hospital of Prato, Tuscany, Italy, over a 1 month and half interval of time. The first isolate was recovered on January 26 from an outpatient with enteritis. Then, two strains were isolated on February 16 and March 11 respectively, from central venous catheters of patients who were being hospitalized in two departments of the Hospital. An epidemiologically linked cluster of cases of salmonellosis was suspected. The three strains were submitted to single enzyme-amplified fragment length polymorphism (SE-AFLP) and XbaI macrorestriction and pulsed-…

Mitochondrial DNA effects on fitness in Drosophila subobscura

2011

We tested different fitness components on a series of conspecific mtDNA haplotypes, detected by RFLPs in Drosophila subobscura. Additionally, haplotype VIII, endemic to the Canary Islands, was tested upon its own native nuclear DNA background and upon that of the rest of mtDNAs tested herein. We found that both nuclear and mitochondrial DNA can have a significant effect upon their hosts' fitness, and that negative selection is one of the mechanisms that can intervene in this species' mtDNA haplotype pattern. We discuss the importance of this mechanism in relation to genetic drift, in the form of periodic population bottlenecks, and how the latter can enhance the former. We also detected a s…
