ABSTRACT Development of 108 epidemics of Fusarium wilt of chickpea caused by Fusarium oxysporum f. sp. ciceris were studied on cvs. P-2245 and PV-61 in field microplots artificially infested with races 0 and 5 of F. oxysporum f. sp. ciceris in 1986 to 1989. Disease progression data were fitted to the Richards model using nonlinear regression. The shape parameter was influenced primarily by date...

MicroRNAs (miRNAs) suppress the transcriptional and post-transcriptional expression of genes in plants. Several miRNA families target genes encoding nucleotide-binding site-leucine-rich repeat (NB-LRR) plant innate immune receptors. The fungus Fusarium oxysporum f. sp. lycopersici causes vascular wilt disease in tomato. We explored a role for miRNAs in tomato defense against F. oxysporum using ...

in this study, trichoderma harzianum bi was evaluated for its capability to reduce the incidence and severity of the root-knot nematode, meloidogyne javanica, and fusarium wilt, f. oxysporum f. sp. lycopersici, as causal agents of a complex disease of tomato in the laboratory and greenhouse conditions. initial in vitro studies revealed that the parasitism of m. javanica eggs by t. harzianum bi ...

Characterization of plant resistance genes is an important step in understanding plant defense mechanisms. Fusarium oxysporum f sp lycopersici is the causal agent of a vascular wilt disease in tomato. Genes conferring resistance to plant vascular diseases have yet to be described molecularly. Members of a new multigene family, complex I2C, were isolated by map-based cloning from the I2 F. o. ly...

Horizontal chromosome transfer introduces host-specific pathogenicity among members of the Fusarium oxysporum species complex and is responsible for some of the most destructive and intractable plant diseases. This paper reports the genome sequence of F. oxysporum f. sp. melonis (NRRL 26406), a causal agent of Fusarium wilt disease on melon.

Fusarium head blight caused by oxysporum f. sp. Radicis-lycopersici (FORL) is a constraint to tomato cultivation in Korhogo, Côte dIvoire. To control this disease, the antifungal activity of essential oils extracted from certain plants was evaluated comparison with that synthetic fungicide for use. In vitro tests were performed on different life stages FORL. The vivo evaluations consisted ca...

ABSTRACT Fusarium oxysporum f. sp. ciceris and the root-lesion nematode Pratylenchus thornei coinfect chickpeas in southern Spain. The influence of root infection by P. thornei on the reaction of Fusarium wilt-susceptible (CPS 1 and PV 61) and wilt-resistant (UC 27) chickpea cultivars to F. oxysporum f. sp. ciceris race 5 was investigated under controlled and field conditions. Severity of Fusar...
