An Israeli breeding line, BIZ, resistant to all four races of Fusarium oxysporum f.sp. melonis (FOM), has been characterized regarding its response to FOM race 1.2. The infection process of a FOM 1.2 strain that expresses the GFP reporter protein was monitored, suggesting the timing and sites in which fungal progression differs between a resistant and a susceptible genotype. A mapping populatio...

The soil-borne fungus Fusarium oxysporum causes vascular wilts of a wide variety of plant species by directly penetrating roots and colonizing the vascular tissue. The pathogenicity mutant B60 of the melon wilt pathogen F. oxysporum f. sp. melonis was isolated previously by restriction enzyme-mediated DNA integration mutagenesis. Molecular analysis of B60 identified the affected gene, designate...

during 2003-2004, a number of rhizospheric soil samples were collected of either healthy or symptomatic field grown melon plants infected with fusarium oxysporum f. sp. melonis race1/2 (fom). twenty one bacterial strains capable of inhibiting fom including burkholderia sp., bacillus sp., streptomyces sp. and pseudomonas fluorescens were isolated. the strains colonized roots of “long melon” cult...

Formae speciales (ff.spp.) of the fungus Fusarium oxysporum are often polyphyletic within the species complex, making it impossible to identify them on the basis of conserved genes. However, sequences that determine host-specific pathogenicity may be expected to be similar between strains within the same forma specialis. Whole genome sequencing was performed on strains from five different ff.sp...

Here, we present the genome sequence of an isolate (14004) of Fusarium oxysporum f. sp. melongenae, an eggplant pathogen. The final assembly consists of 1,631 scaffolds with 53,986,354 bp (G+C content, 46.4%) and 16,485 predicted genes.

3'-Hydroxylation of isoflavones by Fusarium oxysporum f. lycopersici mainly proceeds with 4'-methoxy-7-hydroxyderivatives; this reaction is used for quantitative conversion of 14C-labelled isoflavones.

fusarium wilt of melon is a destructive fungal disease throughout the world. in this study, the evolutionary relationships among isolates of different formae speciales of fusarium oxysporum was examined, with a special emphasis on the forma specialis melonis. bootstrapped maximum likelihood analysis of the elongation factor-1α (ef-1α) sequence was conducted on 16 iranian and 11 foreign isolates...
