Functional Characterisation of the Quorum-Sensing Regulator ExpR_Ecz in Modulation of Dickeya oryzae Motility and Virulence. [PDF]

Mol Plant Pathol
In the absence of OHHL synthase ExpIEcz, ExpREcz represses self‐expression via EDDR region and regulates Dickeya oryzae virulence traits. OHHL synthesised via ExpIEcz abolishes ExpREcz function but promotes OHHL production and D. oryzae virulence.

Plant Immunity-Activating Endophytic Bacteria Induce Dynamic Metabolic Changes in Cultured Plant Cells Without Inhibiting Their Growth. [PDF]

Microb Biotechnol
‘Plant immunity–activating endophytic bacteria’ induce dynamic metabolic changes in cultured plant cells without inhibiting their growth. Co‐culture of plant cells with these bacteria has great potential for the production of valuable phytochemicals.

Regulation of the expression of prtW::gusA fusions in Erwinia carotovora subsp. carotovora [PDF]

Microbiology (United Kingdom), 2002
Erwinia carotovora subsp. carotovora, a Gram-negative phytopathogenic bacterium, secretes an extracellular metalloprotease, PrtW. Previous results demonstrated that protease activity is necessary for the normal progression of disease symptoms caused by this bacterium.

Comparison of pectic enzymes produced by Erwinia chrysanthemi, Erwinia carotovora subsp. carotovora, and Erwinia carotovora subsp. atroseptica [PDF]

Applied and Environmental Microbiology, 1986
Erwinia spp. that cause soft-rot diseases in plants produce a variety of extracellular pectic enzymes. To assess the correlation between patterns of pectic enzyme production and taxonomic classification, we compared the enzymes from representative strains.

Comparative Study of Regulatory Mechanisms for Pectinase Production by Erwinia carotovora subsp. carotovora and Erwinia chrysanthemi [PDF]

Molecular Plant-Microbe Interactions, 2003
The production of pectinase, the major virulence determinant of soft-rot Erwinia species, is controlled by many regulatory factors. We focused on the major regulatory proteins, KdgR, CRP, Pir, and PecS, characterized mainly in E. chrysanthemi, and tested

Elicitation of salicylic acid and methyl jasmonate provides molecular and physiological evidence for potato susceptibility to infection by Erwinia carotovora subsp. carotovora [PDF]

Heliyon
Among the range of severe plant diseases, bacterial soft rot caused by Erwinia carotovora is a significant threat to crops. This study aimed to examine the varying response patterns of distinct potato cultivars to the influence of E.

Genomic diversity of Erwinia carotovora subsp. carotovora and its correlation with virulence. [PDF]

Appl Environ Microbiol, 2004
ABSTRACT We used genetic and biochemical methods to examine the genomic diversity of the enterobacterial plant pathogen Erwinia carotovora subsp. carotovora . The results obtained with each method showed that E. carotovora subsp. carotovora

Biological control of potato soft rot caused by Erwinia carotovora subsp. carotovora

Egyptian Journal of Biological Pest Control, 2018
Four bioagents, Bacillus subtilis, Pseudomonas fluorescence, P. aeruginosa, and Streptomyces spp., were used in vitro and in vivo against two pathogenic isolates of Erwinia carotovora subsp. carotovora (Ecc1 and Ecc2), the causal agent of potato soft rot.
