Characterization of Erwinia amylovora Strains from Croatia [PDF]

European Journal of Plant Pathology, 2006
Erwinia amylovora is the causative agent of fire blight, a destructive disease of rosaceous plants. The European population can be divided into several subtypes according to differences in restriction fragment length polymorphism of the XbaI genomic DNA digest analysed with pulsed-field gel electrophoresis. This technique was also used to determine the

Systems level analysis of two-component signal transduction systems in Erwinia amylovora: Role in virulence, regulation of amylovoran biosynthesis and swarming motility

BMC Genomics, 2009
Background Two-component signal transduction systems (TCSTs), consisting of a histidine kinase (HK) and a response regulator (RR), represent a major paradigm for signal transduction in prokaryotes.

ECONOMIC IMPORTANCE AND PHYTOSANITARY MONITORING OF FIRE BLIGHT [PDF]

Scientific Papers Series : Management, Economic Engineering in Agriculture and Rural Development, 2023
Fire blight (FB) caused by Erwinia amylovora, is a bacterial plant disease that poses a significant threat to pome fruit production worldwide. It can cause extensive losses in fruit yields, damage orchards and lead to trade restrictions on fruit exports.

Erwinia species identification using matrix-assisted laser desorption ionization-time of flight mass spectrometry [PDF]

, 2017
Rapid and reliable identification of plant pathogenic bacteria is critical for effective implementation of phytosanitary measures. The genus Erwinia includes a number of economically important plant pathogens such as fire blight agent Erwinia amylovora ...

The MarR Family Transcriptional Regulator EmrR Negatively Regulates the Type III Secretion System (T3SS) and Positively Modulates Pathogenicity in Dickeya oryzae

Molecular Plant Pathology, Volume 27, Issue 4, April 2026.
This study revealed that the transcriptional regulator EmrR in Dickeya oryzae modulates virulence by regulating hrpL expression and c‐di‐GMP levels. It affects motility, biofilm formation, cellulase production and pathogenicity. EMSA and footprinting confirmed EmrR binds directly to the promoter of its target operon.

Testing of pear trees on their own roots in comparison with important used rootstocks under organic farming conditions with special regard to fire blight (E. amylovora) [PDF]

, 2008
Pear trees on their own roots are tested in comparison to grafted trees in growth and yield characteristics and with special regard to the tolerance to diseases, above all fire blight (Erwinia amylovora).

Haplotype‐phased ‘Ottawa 3’ genome unravels differential reaction of apple rootstock roots to mixed viral infection

The Plant Journal, Volume 126, Issue 1, April 2026.
SUMMARY Viral diseases pose a significant threat to global apple (Malus spp.) production. While selecting appropriate rootstocks is a crucial strategy to mitigate their effects, the underlying mechanisms governing rootstock tolerance or sensitivity to viral infection at the root level remain underexplored.
