American ginseng (Panax quinquefolius L.) is a highly valuable herb widely used for medicinal treatments. Its pharmacologically important compounds are the ginsenosides, which are secondary metabolites in American ginseng root. The concentrations of ginsenoside in roots can be changed by fungal infection, but it is unclear what specific root tissues are impacted and whether the change is system...

Fusarium oxysporum f. sp. ciceri and Meloidogyne javanica are important pathogens of chickpea. Interrelationships between Fusarium oxysporum f. sp. ciceri and M. javanica were investigated on 53 Fusarium wilt-resistant chickpea genotypes in pot experiments. All of the genotypes were susceptible to M. javanica. Fusarium wilt resistance in one genotype (ICC 12275) was ineffective in the presence ...

An isolate of non-pathogenic Fusarium, Fusarium oxysporum 101-2 (NPF), induces resistance in the cuttings of morning glory against Fusarium wilt caused by F. oxysporum f. sp. batatas O-17 (PF). The effect of NPF on phenylpropanoid metabolism in morning glory cuttings was studied. It was found that morning glory tissues responded to treatment with NPF bud-cell suspension (108 bud-cells/ml) with ...

Arabidopsis thaliana ecotypes differ in their susceptibility to Fusarium wilt diseases. Ecotype Taynuilt-0 (Ty-0) is susceptible to Fusarium oxysporum forma specialis (f.) matthioli whereas Columbia-0 (Col-0) is resistant. Segregation analysis of a cross between Ty-0 and Col-0 revealed six dominant RESISTANCE TO FUSARIUM OXYSPORUM (RFO) loci that significantly contribute to f. matthioli resista...
