The present study aimed at the molecular characterization of pathogenic and non pathogenic F. oxysporum f. sp. lycopersici strains isolated from tomato. The causal agent isolated from symptomatic plants and soil samples was identified based on morphological and molecular analyses. Pathogenicity testing of 69 strains on five susceptible tomato varieties showed 45% of the strains were highly viru...

We investigated the diversity of endophytic fungi found on grape (Vitis labrusca cv. Niagara Rosada) leaves collected from Salesópolis, SP, Brazil. The fungi were isolated and characterized by amplified ribosomal DNA restriction analysis, followed by sequencing of the ITS1-5.8S-ITS2 rDNA. In addition, the ability of these endophytic fungi to inhibit the grapevine pathogen Fusarium oxysporum f. ...

Forty-five fungal isolates from moldy supermarket foods were tested for toxicity to brine shrimp, and twenty-two of these isolates were subsequently tested for toxicity to chicken embryos. Highly toxigenic fungi were Cladosporium sphaerospermum from a bakery product, Fusarium oxysporum from carrots, F. solani from cabbage, Aspergillus niger and Penicillium corylophilum from bread, P. cyclopium ...

Effects of four fungi and six rhizobacteria isolates from the rhizosphere of vegetable crops was studied for suppression of root knot nematode, Meloidogyne incognita and wilt fungus, Fusarium oxysporum f. sp. lycopersici on tomato in laboratory and pot culture experiment. All the isolates were isolated by serial dilution and cultured in liquid protein supplemented broth medium and culture filtr...

The ability of Fusarium species isolated from bananas to produce mycotoxins was studied with 66 isolates of the following species: F. semitectum var. majus (8 isolates), F. camptoceras (3 isolates), a Fusarium sp. (3 isolates), F. moniliforme (16 isolates), F. proliferatum (9 isolates), F. subglutinans (3 isolates), F. solani (3 isolates), F. oxysporum (5 isolates), F. graminearum (7 isolates),...

Fusarium wilt of spinach, caused by oxysporum f. sp. spinaciae, is an important disease during warm conditions in production regions with acid soils, yet little known about what confers pathogenicity to spinach F. spinaciae genetically. To identify candidate fungal genes that contribute wilt, each 69 geographically diverse isolates was tested for on three inbreds. Thirty-nine identified as quan...

Due to the restricted genetic diversity among current asparagus cultivars, wild relatives are of particular interest as a source resistance. In this study, seventeen cultivars and were tested for their resistance Fusarium oxysporum in seedling test. Two isolates differing virulence (single spore lines with high low virulence) used testing. Most genotypes showed infestation, whereby Asparagus ae...

Chickpea (Cicer arietinum L.) is one of the most important legume crops in Iran. Wilt disease caused by Fusarium oxysporum f. sp. ciceri, is the most important soil-borne disease of chickpea in the world. This disease caused high losses in different regions during recent years. Simple sequence repeat (SSR) were used to estimate genetic diversity in 114 of F. oxysporum isolates from six counties...

background and purpose: fusarium species are avid producers of secondary toxic and carcinogenic metabolites such as fumonisin. contamination of food and feed products with fumonisin can be hazardous to the health of humans and animals and may lead to agricultural loss. accordingly, in this study, we aimed to evaluate the effects of candida parapsilosis on the growth and fumonisin production of ...
