Epidemiology of Erwinia pyrifoliae, a new pathogen on strawberry in The Netherlands

Acta Horticulturae, 2017
During the late spring of 2013 strawberry plants (Fragaria × ananassa Duch. 'Elsanta') were showing an intense blackening of their immature fruits, their fruit calyxes and the peduncule were found at several locations (greenhouses) in The Netherlands. Symptoms include brown petals, green young fruits turning brown, malformed fruits and bacterium slime (

Erwinia pyrifoliae, a Causal Endemic Pathogen of Shoot Blight of Asian Pear Tree in Korea [PDF]

Plant Pathology Journal, 2003
Bacterial strains were isolated from diseased samples of shoot blight collected from different pear growing orchards of Chuncheon, Korea from 1995 to 1998. Forty-nine strains showed their pathogenicity on immature fruit and shoot of pear. Microbiological, physiological, and biochemical tests were performed on these pathogenic strains.

Characterisation of the stbD/E toxin–antitoxin system of pEP36, a plasmid of the plant pathogen Erwinia pyrifoliae

Plasmid, 2013
pEP36 is a plasmid ubiquitously present in Erwinia pyrifoliae, a pathogen which causes black stem blight of Asian pear. pEP36 is highly stable in its host, even in the absence of selective pressure. The plasmid is closely related to pEA29, which is widespread in E. amylovora, the causative agent of fire blight of apple and pear trees.

Erwinia pyrifoliae , an Erwinia species different from Erwinia amylovora , causes a necrotic disease of Asian pear trees

Plant Pathology, 1999
Bacteria from necrotic branches of Asian pear trees ( Pyrus pyrifolia ) in Korea were consistently isolated as white colonies on nutrient agar and formed mucoid, slightly yellow colonies on a minimal medium with copper sulphate. Isolates with this colony morphology were studied in a series of

Identification of dspEF, hrpW, and hrpN loci and characterization of the hrpNEp gene in Erwinia pyrifoliae

Journal of General Plant Pathology, 2005
Erwinia pyrifoliae, the causal pathogen of shoot blight in the Asian pear tree (Pyrus pyrifolia cv. Singo), is host-specific and endemic to Korea. To identify the genes associated with the hypersensitive response (HR) and pathogenicity, a genomic library of E.

Species-specific Detection of Erwinia pyrifoliae by PCR Assay Using Enterobacterial Repetivive Intergenic Consensus (ERIC) Primers [PDF]

Plant Pathology Journal, 2010
We designed a sensitive and specific PCR-based method with enterobacterial repetitive intergenic consensus (ERIC) primer to detect Erwinia pyrifoliae, which cause shoot blight in Asian pear, from a mixed culture and infected plant materials. The primers specifically detected only E.

Erwinia isolates from the bacterial shoot blight of pear in Japan are closely related to Erwinia pyrifoliae based on phylogenetic analyses of gyrB and rpoD genes

Journal of General Plant Pathology, 2007
The phylogenetic relationships among Erwinia amylovora biovar 4 (the pathogen of bacterial shoot blight of pear in Japan), other biovars of E. amylovora, and Erwinia pyrifoliae were investigated using the sequences of 16S rRNA, gyrB, and rpoD genes. The tested isolates formed two distinct monophyletic groups in the phylogenetic trees constructed based ...

Erwinia pyrifoliae, a new pathogen on strawberry in the Netherlands

2015
BACKGROUND: During the late spring of 2013 strawberry plants grown under protection (Fragaria x ananassa cv. Elsanta) were found at several locations in the Netherlands showing an intense brown to black discoloration of their immature fruits, their fruit calyx and the attached stems.
