Engineering the bacterial nutrition strategy to control plant diseases

Journal of Integrative Plant Biology, EarlyView.
This commentary on Wang et al. (2025) and Phan et al. (2025) highlights previously undiscovered Xanthomonas pathways for nutrition acquisition, explains how Xanthomonas bacteria hijack host molecular machinery through their effector proteins, and discusses how these studies can be used to develop new disease resistance mechanisms.

A stage‐dependent seed defense response to explain efficient seed transmission of Xanthomonas citri pv. fuscans to common bean

Plant, Cell &Environment, EarlyView.
Abstract Although seed represents an important means of plant pathogen dispersion, the seed–pathogen dialogue remains largely unexplored. A multiomic approach was performed at different seed developmental stages of common bean (Phaseolus vulgaris L.) during asymptomatic colonization by Xanthomonas citri pv.

Positive regulation of Type III secretion effectors and virulence by RyhB paralogs in Salmonella enterica serovar Enteritidis

Veterinary Research, 2021
Small non-coding RNA RyhB is a key regulator of iron homeostasis in bacteria by sensing iron availability in the environment. Although RyhB is known to influence bacterial virulence by interacting with iron metabolism related regulators, its interaction ...

Functions of the Salmonella pathogenicity island 2 (SPI-2) type III secretion system effectors.

Microbiology, 2012
Salmonella enterica serovars cause severe disease in humans, such as gastroenteritis and typhoid fever. The bacteria are able to invade and replicate within host cells, including epithelial cells and macrophages. Pathogenesis of Salmonella is facilitated

Insights Into the Role of Lysine Acetylation of Non‐Histone Proteins in Plant Immunity

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant immunity is regulated by numerous transcriptional and posttranslational mechanisms. Among these, lysine acetylation, which is controlled by lysine acetyltransferases (KATs) and lysine deacetylases (KDACs), has been extensively studied, particularly in the context of epigenetic regulation through histone acetylation.

Differential regulation of Shigella Spa47 ATPase activity by a native C-terminal product of Spa33

Frontiers in Cellular and Infection Microbiology, 2023
Shigella is a Gram-negative bacterial pathogen that relies on a single type three secretion system (T3SS) as its primary virulence factor. The T3SS includes a highly conserved needle-like apparatus that directly injects bacterial effector proteins into ...

Transcriptome Analysis Reveals Cross‐Kingdom Virulence Factors in Erwinia persicina Cp2

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Pathogenic mechanism of Erwinia persicina Cp2 across plant and animal kingdoms. ABSTRACT Erwinia persicina is a well‐documented plant pathogenic bacterium, causing soft rot in various plant hosts. There are rare previous reports that it is associated with animal diseases.

Steps for Shigella Gatekeeper MxiC Function in Hierarchical Type III Secretion Regulation [PDF]

, 2017
Type III secretion systems are complex nanomachines used for injection of proteins from Gram-negative bacteria into eukaryotic cells. Although they are assembled when the environmental conditions are appropriate, they only start secreting upon contact ...

Characterization of the Mesorhizobium loti MAFF303099 Type-Three Protein Secretion System

Molecular Plant-Microbe Interactions, 2009
Type III secretion systems (T3SS) have been found in several species of rhizobia. Proteins (termed effectors) secreted by this system are involved in host-range determination and influence nodulation efficiency.
