Fusarium oxysporum f. sp. ginseng, a new forma specialis causing Fusarium root rot of Panax ginseng

نویسندگان

چکیده

Panax ginseng is a valuable medicinal plant which affected by many diseases during its long cultivation period. Ginseng root rot, caused Fusarium oxysporum, has become severe in China. This soilborne pathogen comprises formae speciales based on host specificity. Ten representative isolates from diseased rot showed pathogenicity ginseng. To identify the forma specialis of F. oxysporum strains, range tests three were carried out nine species. All symptoms only ginseng, but slight or no visual other eight hosts, indicating that strains host-specific to Phylogenetic trees constructed sequences translation elongation factor 1-α (EF-1α) gene, two endopolygalacturonase genes (Pg1, Pg5) and exopolygalacturonase (Pgx1 Pgx4). The ten clustered into unique group clearly separated already described. Based phylogenetic analyses, derived have been identified as new specialis, designated f. sp. first report

Differential Responses of Vanilla Accessions to Root Rot and Colonization by Fusarium oxysporum f. sp. radicis-vanillae

Root and stem rot (RSR) disease caused by Fusarium oxysporum f. sp. radicis-vanillae (Forv) is the most damaging disease of vanilla (Vanilla planifolia and V. × tahitensis, Orchidaceae). Breeding programs aimed at developing resistant vanilla varieties are hampered by the scarcity of sources of resistance to RSR and insufficient knowledge about the histopathology of Forv. In this work we have (...
