Abstract Fusarium is one of the most important genera phytopathogenic fungi, causing potato wilt in field and tuber dry rot during storage. The objectives this study were to identify species associated with both diseases different growing regions Algeria, assess their pathogenicity. Among 152 isolates collected from symptomatic plants tubers provinces 13 Neocosmospora identified. these three is...

Fifty fungal isolates were sampled from diseased tomato plants as result of a survey conducted in seven tomato crop areas in Algeria from 2012 to 2015. Morphological criteria and PCR-based identification, using the primers PF02 and PF03, assigned 29 out of 50 isolates to Fusarium oxysporum (Fo). The banding patterns amplified for genes SIX1, SIX3 and SIX4 served to identify races 2 and 3 of Fo ...

CdSe quantum dots are often used in industry as fluorescent materials. In this study, CdSe quantum dots were synthesized using Fusarium oxysporum. The cadmium and selenium concentration, pH, and temperature for the culture of F. oxysporum (Fusarium oxysporum) were optimized for the synthesis, and the CdSe quantum dots obtained from the mycelial cells of F. oxysporum were observed by transmissio...

Fusarium oxysporum f. sp. pisi (Fop) is a pathogen of field pea inducing severe vascular wilt worldwide. Plant resistance to races 1, 5, and 6, producing wilt symptoms, is conferred by a single dominant gene, while resistance to race 2, which gives near-wilt symptoms, have been recently showed to be quantitative. Among the virulence factors reported to play a role in the infection process, toxi...

broomrape (orobanche spp.) is one of the most serious weed pathogen on many dicotyledonous plants such as tomato, cucumber, melon, tobacco and others. this weed parasite caused serious problem in tomato cultivation fields, especially in north west iran. some isolates of fusarium spp. and pseudomonas fluorescens are known as effective biological agents in biocontrol of this weed. in order to fin...

Introduction: Tomato production in Ethiopia is challenged by many pests and diseases. Fusarium wilt one of the most important diseases tomato affecting its productivity. Methods: tissue soil samples were collected from farmlands around Aksum town to isolate identify pathogenic species Trichoderma with biocontrol efficacy. Samples processed University Biotechnology laboratory following standard ...

Many studies have shown that several Greek ecosystems inhabit very interesting bacteria with biotechnological properties. Therefore Streptomyces isolates from diverse Greek habitats were selected for their antifungal activity against the common phytopathogenic fungus Fusarium oxysporum. The isolate encoded ACTA1551, member of Streptomyces genus, could strongly suppress the fungal growth when ex...

Natural contamination by zearalenone, a toxic metabolite of Fusarium fungi, was surveyed in 160 samples of sorghum imported from 2001 to 2006 into Japan for feed. Of these 160 samples, 84 (52.5%) were contaminated with zearalenone, ranging in concentration from 60 to 7.260 microg/kg. In the contaminated sorghum samples, F. semitectum, F. verticillioides, F. oxysporum, and other Fusarium spp. we...
