Genetic Organization of the hrp Gene Cluster and dspAE/BF Operon in Erwinia herbicola pv. gypsophilae

Molecular Plant-Microbe Interactions, 2001
Erwinia herbicola pv. gypsophilae induces gall formation in gypsophila that is dependent on the existence of a pathogenicity plasmid (pPATHEhg). We previously demonstrated the presence of several hrp genes on this plasmid.

Conservation challenges and opportunities for native apple (Malus) species in Canada

PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 134-156, January 2026.
Apple, one of the world's most widely cultivated and economically important fruit crops, has two wild relatives native to Canada. In this review, we describe the importance of these native apple species to Indigenous heritage and the current threats the species faces due to pests, diseases, and habitat loss.

Evaluation of pathogenicity variation between two Erwinia species in apples and their population using a duplex real-time PCR method

Frontiers in Microbiology
Fire blight and black shoot blight diseases, caused by Erwinia amylovora and Erwinia pyrifoliae, respectively, continue to spread several areas in Korea, despite intensive efforts by the government to control diseases.

Secreted Glycoside Hydrolase BcGH61 From Botrytis cinerea Induces Cell Death by the Apoplastic Location and Triggers Intracellular Immune Perception

Molecular Plant Pathology, Volume 27, Issue 1, January 2026.
We present a dual‐action virulence paradigm for BcGH61: Extracellularly, BcGH61 glycoside hydrolase degrades cell walls, releasing DAMPs that activate PRR‐mediated cell death. Intracellularly, it targets chloroplasts via NbHrBP1 interaction at plastoglobule‐thylakoid interfaces, paradoxically activating defence signalling while priming immunity‐related

Phenotypic Diversity of Erwinia amylovora in Bulgaria

Zeitschrift für Naturforschung C, 2007
Fifty-one strains of Erwinia amylovora isolated from nine host plants in Bulgaria were characterized phenotypically and identified by the API 20E and BIOLOG system. The identification was confirmed by PCR amplification of a specific region of the plasmid pEA29 and the genome ams region.

Effects of Lipopolysaccharide Core Modulation on Outer Membrane Protein Function and Virulence in Pectobacterium carotovorum

Molecular Plant Pathology, Volume 27, Issue 1, January 2026.
The LPS core is critical for virulence in Pectobacterium carotovorum, as its truncation disrupts outer membrane protein assembly, reducing protease secretion, motility, and soft rot symptoms. ABSTRACT Lipopolysaccharide (LPS) is a critical component of the bacterial outer membrane, which serves as a permeability barrier and site for sensing ...

Erwinia amylovora in the genomics era : from genomes to pathogen virulence, regulation, and disease control strategies [PDF]

, 2017
The publication of the first Erwinia amylovora genome has greatly accelerated and advanced our understanding of the fire blight organism. With the availability of multiple genomes, it quickly became clear that chromosomal diversity is relatively small ...

EUROPEAN PROTOCOL FOR DIAGNOSIS OF ERWINIA AMYLOVORA

Acta Horticulturae, 2006
The EU-funded project DIAGPRO has developed diagnostic protocols for 18 quarantine pests including Erwinia amylovora. The protocol for this organism includes a diagnosis scheme for detection of the bacterium in symptomatic and asymptomatic plants with details of the different techniques as isolation in three media, direct tissue print-ELISA, enrichment
