fire blight is an important worldwide disease of pome fruits that control of which through antibiotics is particularly critical. in this case and in absence of another chemical methods, the biocontrol methods can be considered as the best alternative for control of fire blight. in this study efficacy of 5 isolates of antagonistic bacteria belongs to pseudomonas fluorescens and pantoea agglomera...
Fire blight, caused by Erwinia amylovora (Ea), is a destructive disease of Malus (apple), Pyrus (pear) and some woody ornamentals in the rose family (Rosaceae). The goal of this project is to use a functional genomics approach to develop tools to breed fire blight resistant apples. Suppression subtractive hybridization (SSH) and cDNA-AFLP analysis were used to identify 650 expressed sequence ta...
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-deox...

Erwinia amylovora is the causative agent of fire blight, a serious disease of some Rosaceae plants. The newly isolated bacteriophage PhiEaH2 is able to lyse E. amylovora in the laboratory and has reduced the occurrence of fire blight cases in field experiments. This study presents the sequenced complete genome and analysis of phage PhiEaH2.
Management of fire blight is complicated by limitations on use of antibiotics in agriculture, antibiotic resistance development, and limited efficacy of alternative control agents. Even though successful in control, preventive antibiotic sprays also affect non-target bacteria, aiding the selection for resistance which could ultimately be transferred to the pathogen Erwinia amylovora. Trunk inje...
in the current study, molecular typing of 50 erwinia amylovora strains related to different regions in iran was evaluated using multi-locus sequence analysis and variable number of tandem repeats. in the first assay, phylogenetic tree based on partial sequences of recombinase a, sigma factor s and a heat shock protein groel showed significant identity in studied gene sequences. a single nucleot...
Since several Asian pear species are considered to be potential source of fire blight resistance, we crossed ‘Doyenné du Comice’, the susceptible European cultivar, with four Asian pear species. The aim of the study was to establish the level of resistance of each genotype and the mode of transmission of fire blight resistance to each F1 full-sib progeny. The best sources of resistance were P. ...
Erwinia amylovora is a Gram-negative bacterial plant pathogen in the family Enterobacteriaceae and is the causal agent of fire blight, a devastating disease of apple and pear. Fire blight is traditionally managed by the application of the antibiotic streptomycin during bloom, but this strategy has been challenged by the development and spread of streptomycin resistance. Thus, there is an urgent...
The molecular basis of resistance and susceptibility of host plants to fire blight, a major disease threat to pome fruit production globally, is largely unknown. RNA-sequencing data from challenged and mock-inoculated flowers were analyzed to assess the susceptible response of apple to the fire blight pathogen Erwinia amylovora. In presence of the pathogen 1,080 transcripts were differentially ...
