Occurrence of Dickeya and Pectobacterium in Lake Water and the Rhizosphere of Waterside Plants Collected in the French Region La Dombes [PDF]

Microorganisms
Pectinolytic bacteria of the Pectobacteriaceae family constitute an important group of plant pathogens. Apart from infected plants, they are regularly found in aquatic environments.

Integrated 16S rRNA Sequencing and Metabolomics Reveals Niche-Specific Microbiome and Metabolome Changes Associated with Toxoptera aurantii Infestation [PDF]

Microorganisms
Toxoptera aurantii is a globally distributed piercing-sucking pest that severely threatens tea production. While the direct damage caused by aphid feeding is well documented, the systemic effects of infestation on plant-associated and soil microbial ...

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.

Early Emergence of Dickeya solani Revealed by Analysis of Dickeya Diversity of Potato Blackleg and Soft Rot Causing Pathogens in Switzerland [PDF]

Microorganisms, 2021
Blackleg and soft rot in potato caused by Pectobacterium and Dickeya enterobacteral genera are among the most destructive bacterial diseases in this crop worldwide. In Europe, over the last century, Pectobacterium spp.

Tailocin-Mediated Interactions Among Soft Rot Pectobacteriaceae. [PDF]

Mol Ecol
ABSTRACT Bacteria carry phage‐derived elements within their genomes, some of which can produce phage‐like particles (tailocins) used as weapons to kill kin strains in response to environmental conditions. This study investigates the production and activity of tailocins by plant‐pathogenic bacteria: Pectobacterium, Dickeya, and Musicola genera, which ...

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

Mol Plant Pathol
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.

Crystal structure of endo-β-1,6-galactanase from Streptomyces avermitilis. [PDF]

Acta Crystallogr D Struct Biol
The crystal structure of S. avermitilis endo‐β‐1,6‐galactanase belonging to GH30 subfamily 5 reveals the first structural framework for endo‐β‐1,6‐galactanase. The β‐1,6‐galactobiose‐bound complex identifies the catalytic subsites and a distal secondary sugar‐binding site, providing insight into β‐1,6‐galactan recognition.Endo‐β‐1,6‐galactanases ...

Natural Infections of Potato Plants Grown from Minitubers with Blackleg-Causing Soft Rot Pectobacteriaceae [PDF]

Microorganisms, 2022
Information on the infection incidence of blackleg-causing soft rot Pectobacteriaceae (BL-SRP) in potato crops grown from minitubers (PB1-crop) and the distribution of BL-SRP in individual plants was collected during a two-year survey conducted at five ...

Hyperinduction of pectate lyase in Dickeya chrysanthemi EC16 by plant-derived sugars

Journal of Plant Interactions, 2018
Pectate lyase (Pel) synthesis in Dickeya chrysanthemi has been reported to be hyperinduced in planta and also in the medium containing plant extract in addition to polygalacturonate. In this study, the major components of Pel-hyperinducing fractions were

Dynamic Regulation of GacA in Type III Secretion, Pectinase Gene Expression, Pellicle Formation, and Pathogenicity of Dickeya dadantii (Erwinia chrysanthemi 3937)

Molecular Plant-Microbe Interactions, 2008
Dickeya dadantii (Erwinia chrysanthemi 3937) secretes exoenzymes, including pectin-degrading enzymes, leading to the loss of structural integrity of plant cell walls.
