Molecular design and synthesis of novel salicyl glycoconjugates as elicitors against plant diseases.

A new series of salicyl glycoconjugates containing hydrazide and hydrazone moieties were designed and synthesized. The bioassay indicated that the novel compounds had no in vitro fungicidal activity but showed significant in vivo antifungal activity against the tested fungal pathogens. Some compounds even had superior activity than the commercial fungicides in greenhouse trial.

Biological Control Efficiency of Fusarium Wilt of Tomato by Nonpathogenic Fusarium oxysporum Fo-B2 in Different Environments.

ABSTRACT Efficiency of nonpathogenic Fusarium oxysporum Fo-B2 for the biological control of Fusarium wilt of tomato, caused by F. oxysporum f. sp.

Cerebroside elicitor confers resistance to fusarium disease in various plant species.

ABSTRACT In the rice blast fungus pathosystem, cerebroside, a compound categorized as a sphingolipid, was found in our previous study to be a non-racespecific elicitor, which elicits defense responses in rice. Here we describe that cerebroside C is produced in diverse strains of Fusarium oxysporum, a common soilborne agent of wilt disease affecting a wide range of plant species. In addition, some type of cerebroside elicitor involving cerebroside A, B, or C was detected in other soilborne phytopathogens, such as Pythium and Botrytis.

Generation and characterization of reduced virulence Fusarium oxysporum f. sp. lycopersici mutants through plasmid-vector insertion.

Pathogenicity-impaired mutants, B02 and H15, of Fusarium oxysporum f. sp. lycorpersici (FOL) were obtained using restriction enzyme-mediated integration.
