Induction of antimicrobial 3-deoxyflavonoids in pome fruit trees controls fire blight.

چکیده
Fire blight, a devastating bacterial disease in pome fruits, causes severe economic losses worldwide. Hitherto, an effective control could only be achieved by using antibiotics, but this implies potential risks for human health, livestock and environment. A new approach allows transient inhibition of a step in the flavonoid pathway, thereby inducing the formation of a novel antimicrobial 3-deoxyflavonoid controlling fire blight in apple and pear leaves. This compound is closely related to natural phytoalexins in sorghum. The approach does not only provide a safe method to control fire blight: Resistance against different pathogens is also induced in other crop plants.

متن کاملDevelopment of the Mason Bee, Osmia cornifrons, as a Targeted Delivery System for Biocontrol Agents in the Management of Fire Blight
Introduction This is a multi-disciplinary effort between entomologists and a plant pathologist to address three research priorities as set by the 2008 SHAP research committee. We propose developing a pollinator alternative to the honey bee which specializes in pollinating fruit trees and is not susceptible to the virus causing the Colony Collapse Disorder nor to the mite problems devastating th...
متن کاملPlant agricultural streptomycin formulations do not carry antibiotic resistance genes.
Streptomycin is used in plant agriculture for bacterial disease control, particularly against fire blight in pome fruit orchards. Concerns that this may increase environmental antibiotic resistance have led to bans or restrictions on use. Experience with antibiotic use in animal feeds raises the possible influence of formulation-delivered resistance genes. We demonstrate that agricultural strep...

Monitoring the ability of bacterial plant pathogens to survive in insects is required for elucidating unknown aspects of their epidemiology and for designing appropriate control strategies. Erwinia amylovora is a plant pathogenic bacterium that causes fire blight, a devastating disease in apple and pear commercial orchards. Studies on fire blight spread by insects have mainly focused on pollina...
