Enterobacter Species: Opportunistic Human and Plant Pathogens With Plant‐Beneficial Traits

Molecular Plant Pathology, Volume 27, Issue 3, March 2026.
The pathogen profile on Enterobacter species synthesises current knowledge on host range, disease symptoms, plant‐beneficial traits and compares genomic features within the genus. ABSTRACT Enterobacter species occur across diverse habitats and are best known for causing opportunistic and nosocomial infections in humans.

Structure of the T6SS lipoprotein TssJ1 fromPseudomonas aeruginosa [PDF]

Acta Crystallographica Section F Structural Biology and Crystallization Communications, 2013
The type VI secretion system of Pseudomonas aeruginosa has been shown to be responsible for the translocation of bacteriolytic effectors into competing bacteria. A mechanistic understanding of this widely distributed secretion system is developing and structural studies of its components are ongoing.

Characterization of the RpoN Regulon Reveals Differential Regulation of T6SS and New Flagellar Operons in Vibrio cholerae O37 Strain V52 [PDF]

, 2012
The alternative sigma factor RpoN is an essential colonization factor of Vibrio cholerae and controls important cellular functions including motility and type VI secretion (T6SS). The RpoN regulon has yet to be clearly defined in T6SS-active V.

Virulence Regulation and Lifestyle Transitions: The Role of c‐di‐GMP and Two‐Component Systems in Erwinia amylovora and Their Evolutionary Context Within Enterobacterales

Molecular Plant Pathology, Volume 27, Issue 2, February 2026.
Erwinia amylovora infects apple blossoms by activating the T3SS, then spreads systemically via amylovoran‐mediated biofilms. Transitions between motile and sessile states are regulated by key two‐component systems and c‐di‐GMP. This review summarises infection biology, virulence factors, regulatory networks and evolutionary insights underlying fire ...

Virulence of a T6SS Campylobacter jejuni chicken isolate from North Romania [PDF]

BMC Research Notes, 2019
In this study we have investigated the in vitro and in vivo virulence characteristics of a new T6SS positive Campylobacter jejuni chicken isolate (SV12) originating from a poultry population in North Romania. A detailed phenotypic characterization was performed and compared to the T6SS negative C. jejuni 81-176 wild strain.Our results indicate that the

OmpA_C‐Like Domain of PorE Is Essential for PorE Function in the Type IX Secretion System (T9SS) of Porphyromonas gingivalis and Some T9SS Cargo Proteins Are Secreted in a PorE‐Independent Manner

Microbiology and Immunology, Volume 70, Issue 1, Page 15-26, January 2026.
ABSTRACT The periodontal pathogen Porphyromonas gingivalis secretes gingipains, highly hydrolytic proteases, to the cell surface or external environment via a type IX secretion system (T9SS). PorE is one of the T9SS component proteins essential for gingipain secretion. It consists of four domains: TPR, WD40, CRD, and OmpA_C‐like.

Twists, turns and jumps: T6SS evolution within species

Trends in Microbiology
The type VI secretion system mediates interbacterial antagonism between Gram-negative bacteria through delivery of toxic effector proteins. A recent comprehensive genomic analysis by Habich et al. reveals interesting features of the evolution of T6SSs and their corresponding effectors in Pseudomonas aeruginosa, raising questions about functional ...

Post-phagocytosis activation of NLRP3 inflammasome by two novel T6SS effectors

eLife, 2022
The type VI secretion system (T6SS) is used by bacteria to deliver toxic effectors directly into target cells. Most T6SSs mediate antibacterial activities, whereas the potential anti-eukaryotic role of T6SS remains understudied. Here, we found a Vibrio T6SS that delivers two novel effectors ...

Rhizobium rhizogenes A4‐derived strains mediate hyper‐efficient transient gene expression in Nicotiana benthamiana and other solanaceous plants

Plant Biotechnology Journal, Volume 24, Issue 1, Page 131-144, January 2026.
Summary Agroinfiltration, a method utilizing agrobacteria to transfer DNA into plant cells, is widely used for transient gene expression in plants. Besides the commonly used Agrobacterium strains, Rhizobium rhizogenes can also introduce foreign DNA into host plants for gene expression. While many R. rhizogenes strains have been known for inducing hairy
