Cotton (Gossypium hirsutum) wilt caused by Fusarium oxysporum f. sp. vasinfectum (Fov) is considered as a major threat for commercial cotton production worldwide. Relative expression ratios of two key pathogenesis-related (PR) genes (PR-3 and PR-10) and a detoxification gene (GST18) were compared between a fully susceptible (“LACTA”) and a partially(More)
Agrobacterium tumefaciens-mediated transformation (AMT) was used in order to create fluorescent conidia of Beauveria bassiana (Balsamo) Vuillemin (Ascomycota: Hypocreales). From the fungal transformants, one Enhanced Green Fluorescent Protein B. bassiana strain indicated stability (maintained the GFP characteristics) in fluorescent signal, while its(More)
In the present study, the efficiency of the biocontrol agent Paenibacillus alvei (strain K165) to suppress Verticillium wilt of olive tree was evaluated in greenhouse and field experiments. In planta bioassays were conducted under greenhouse conditions and revealed that K165 significantly decreased symptoms on the susceptible cultivar ‘Amfissis’ by 44.5 and(More)
Fusarium oxysporum f.sp. melonis (FOM) is a plant pathogen affecting melon production worldwide. An environmental friendly disease management strategy is the use of biocontrol agents (BCAs). Towards this direction, two BCA release strategies, seed coating and amendment of the transplant soil plug with the BCA strain Paenibacillus alvei K165 at various(More)
A boll rot of cotton (Gossypium hirsutum L.) was observed for the first time in Greece in August 1993 in Larissa and Volos counties, and in August and September 1995 in Trikala and Phthiotis counties. Fungi of the genusPhytophthora were isolated from diseased plants. Morphological characteristics of the pathogen were recorded on mounts made directly from(More)
A severe crown rot of pear trees of cultivar ‘Kondoula’ grafted on quince rootstock was observed in Greece. Isolations from the affected tissues repeatadly yielded aPhytophthora sp. that was determined by morphological and physiological characteristics to beP. citrophthora. The pathogenicity of two of theP. citrophthora isolates was tested by inoculating(More)
The volatile profile of four different groups of dried pistachios namely: H: healthy, NC: naturally contaminated with aflatoxin, AC: artificially contaminated with aflatoxigenic strains of the fungi Aspergillus flavus and ANT: artificially contaminated with non-toxigenic strains of the fungi A. flavus, was determined. The volatiles were isolated by the(More)
