Microbial communities living in nine vineyards distributed over three altitudinal transects were studied over 2 years. Fungal and bacterial community dynamics were explored using automated ribosomal intergenic spacer analysis (ARISA) and by determining bacterial cells and fungal colony-forming units (CFUs). Moreover, extensive chemical and physical analyses(More)
RATIONALE The study of the interactions among microorganisms, especially between pathogens and other microorganisms, is a very useful way to identify possible biocontrol agents (BCAs). In this study we verified the capability of δ(13)C analysis using isotope ratio mass spectrometry (IRMS) to detect active parasitism or metabolic assimilation of(More)
Soil microorganisms are key determinants of soil fertility and plant health. Soil phytopathogenic fungi are one of the most important causes of crop losses worldwide. Microbial biocontrol agents have been extensively studied as alternatives for controlling phytopathogenic soil microorganisms, but molecular interactions between them have mainly been(More)
Changes in the soil microbial community structure can lead to dramatic changes in the soil ecosystem. Temperature, which is projected to increase with climate change, is commonly assumed to affect microbial communities, but its effects on agricultural soils are not fully understood. We collected soil samples from six vineyards characterised by a difference(More)
Armillaria spp. are the causal agents of root rots of several woody plants, including highbush blueberry. Since 2003, highbush blueberry plants infected by Armillaria spp. have been found in Valsugana Valley, Trentino region, northern Italy. Our aim was to identify the Armillaria spp. involved in these infections, as well as possible sources of inoculum in(More)
Gli AA. riferiscono brevemente intorno ai risultati di uno studio, condotto con l'ausilio della microscopia ottica ed elettronica, sui capillari congiuntivali prelevati mediante biopsia da soggetti diabetici in diverse condizioni di malattia. Le alterazioni riscontrate possono essere così brevemente sintetizzate: 1) microscopia ottica: ispessimento della(More)
Spondylo-epiphyseal dysplasia (SED) is a heterogeneous clinical condition covering many skeletal anomalies, particularly of the spinal column and proximal epiphysis of the long bone. It can be associated with several forms of craniofacial malformations, often with ocular pathologies and only rarely with deafness (recently described as(More)
