occurrence of fire blight caused by erwinia amylovora on quince in kerman province*
fire blight is one of the most destructive diseases of stone and pome fruits. the causal pathogen is erwiniaamylovora, species in the family enterobacteriaceae. pears are the most susceptible, but apples, quinces and some other rosaceous plants are also vulnerable. in iran, the disease has been reported for the first time in baraghan in alborz province (zakeri & sharifnabi 1991). fire blight pr...
متن کاملFire Blight Disease Caused by Erwinia amylovora on Rosaceae Plants in Kyrgyzstan and Biological Agents to Control This Disease
Erwinia amylovora species were isolated from the blossoms, exudates, infected fruits, leaves and bent branches of diseased apple, pear and hawthorn trees, selected in the Chy, Osh and Jalal Abad regions. Biochemical and pathogenicity tests, alongside PCR analyses, were conducted to identify the local isolates of Erwinia amylovora. The alternative antagonistic microorganisms which combat bacteri...
متن کاملthe study of biological control of pear fire blight caused by erwinia amylovora by some antagonistic bacteria
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...
متن کاملIdentification of the fire blight pathogen, Erwinia amylovora, by PCR assays with chromosomal DNA.
Erwinia amylovora, the causative agent of fire blight, was identified independently from the common plasmid pEA29 by three different PCR assays with chromosomal DNA. PCR with two primers was performed with isolated DNA and with whole cells, which were directly added to the assay mixture. The oligonucleotide primers were derived from the ams region, and the PCR product comprised the amsB gene, w...
متن کاملAutoinduction in Erwinia amylovora: evidence of an acyl-homoserine lactone signal in the fire blight pathogen.
Erwinia amylovora causes fire blight disease of apple, pear, and other members of the Rosaceae. Here we present the first evidence for autoinduction in E. amylovora and a role for an N-acyl-homoserine lactone (AHL)-type signal. Two major plant virulence traits, production of extracellular polysaccharides (amylovoran and levan) and tolerance to free oxygen radicals, were controlled in a bacteria...
