Fecha de publicación: | feb-2014 | Editor: | American Chemical Society | Citación: | Journal of Agricultural and Food Chemistry 62(12): 2574-2580 (2014) | Resumen: | 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, toxin production is one of the best studied. Thus, five race 2 isolates have been investigated for toxin production in vitro and their relation to isolates' pathogenicity. All the isolates produced different amounts of fusaric and 9,10-dehydrofusaric acids. The content of the two toxins has been quantitated and correlated with the pathogenicity and aggressiveness of isolates on field pea. Results suggested that toxin production is an important determinant of Fop race 2 pathogenicity. © 2014 American Chemical Society. | Versión del editor: | http://dx.doi.org/10.1021/jf405530g | URI: | http://hdl.handle.net/10261/101101 | DOI: | 10.1021/jf405530g | Identificadores: | doi: 10.1021/jf405530g issn: 0021-8561 e-issn: 1520-5118 |
