Expression analysis of selected potato genes connected to cell wall architecture changes in the potato tuber in response to hypoxic stress during infection with the soft rot-causing agent (Dickeya solani)

Tomasz Maciąg, Dorota M. Krzyżanowska, Robert Czajkowski, Edmund Kozieł et autres

The study aimed to investigate the effects of hypoxia stress and infection with pectinolytic bacteria on changes in the cell wall architecture of potato tubers. Hypoxia stress increases the susceptibility of potato tubers to soft rot, a disease caused by pectinolytic bacteria. …

Beyond kin killing: Dickeya -derived phage-tail-like bacteriocin P2D1 targets phylogenetically distant Pseudomonas spp.

Marcin Borowicz, Jan Styn, Kacper Tomasik, Łukasz Rąbalski et autres

Abstract Tailocins, phage-tail-derived bacteriocins, are increasingly recognized as potent mediators of microbial antagonism, yet their ecological scope beyond kin-targeting remains poorly understood. Here, we investigated whether P2D1, a tailocin produced by the plant pathogen Dickeya dadantii 3937, can act against environmental bacteria …

Stress-driven temporal production of phage tail-like particles (tailocins) in Dickeya dadantii strain 3937

M Sobolewska, Dorota M. Krzyżanowska, Marcin Borowicz, Robert Czajkowski

Tailocins are bacteriocins resembling bacteriophage tails. Previously, we reported the production of tailocins in the plant pathogen Dickeya dadantii 3937, the synthesis of which was upregulated upon treatment with mitomycin C. In this study, we investigated how mitomycin treatment over time influences …

Antagonistic Interactions Between Dickeya solani and Bacillus subtilis

Roberta Gatta, Adam Iwanicki, Robert Czajkowski, Michał Obuchowski

Microorganisms in their natural ecological niches are constantly challenged by other inhabitants. Antagonisms exhibited by interacting microbial species are directed towards survival and increasing of their fitness. The Soft Rot Pectobacteriaceae (SRP) is a good model to study these complex microbial interactions. …

An inner membrane protein is covalently attached to peptidoglycan in the γ-proteobacterium Dickeya dadantii

Xavier Nicolai, Yucheng Liang, Florence Ruaudel, Magdalena Narajczyk et autres

Gram-negative (diderm) bacteria possess a multilayered envelope comprising an inner membrane, a thin peptidoglycan (PG) layer and an outer membrane. In Escherichia coli and certain other γ-proteobacteria, including Dickeya dadantii, Braun lipoprotein, Lpp, covalently tethers the outer membrane to PG. Here, we …

Tailocin‐Mediated Interactions Among Soft Rot Pectobacteriaceae

Marcin Borowicz, Dorota M. Krzyżanowska, M Sobolewska, Magdalena Narajczyk et autres

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 …
