Dickeya Manipulates Multiple Quorum Sensing Systems to Control Virulence and Collective Behaviors

Frontiers in Plant Science, 2022
Soft rot Pectobacteriaceae (SRP), typical of Pectobacterium and Dickeya, are a class of Gram-negative bacterial pathogens that cause devastating diseases on a wide range of crops and ornamental plants worldwide.

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.

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.

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.

Genome Sequence of Dickeya solani, a New soft Rot Pathogen of Potato, Suggests its Emergence May Be Related to a Novel Combination of Non-Ribosomal Peptide/Polyketide Synthetase Clusters

Diversity, 2013
Soft rot Enterobacteria in the genera Pectobacterium and Dickeya cause rotting of many crop plants. A new Dickeya isolate has been suggested to form a separate species, given the name Dickeya solani.

Skin Commensal Microbiota Does Not Influence the Clinical Course of Dermatophyte Infection in Persian Cats. [PDF]

Vet Dermatol
Dermatophytes can be isolated from both symptomatic and asymptomatic cats, yet the role of skin commensals in modulating disease expression remains unclear. This study investigates whether microbial skin communities influence the clinical presentation (symptomatic or asymptomatic) of dermatophyte infection in Persian cats.

Five Plant Natural Products Are Potential Type III Secretion System Inhibitors to Effectively Control Soft-Rot Disease Caused by Dickeya

Frontiers in Microbiology, 2022
Dickeya zeae, a plant soft-rot pathogen, possesses a type III secretion system (T3SS) as one of the major virulence factors, infecting a wide variety of monocotyledonous and dicotyledonous plants and causing serious losses to the production of economic ...
