Beneath the Bark: Molecular Determinants of Adaptation and Infection in Bacterial Pathogens of Woody Hosts

Molecular Plant Pathology, Volume 27, Issue 8, August 2026.
Bacterial pathogens colonise woody hosts by integrating metabolic adaptation, effector‐mediated immune suppression, cell wall remodelling and EPS‐ and toxin‐supported persistence. ABSTRACT Bacterial pathogens of woody plants represent a pervasive yet underexplored threat to global agriculture and forestry, causing devastating diseases in fruit trees ...

GpaR Drives Type III Secretion and Virulence Through Direct Activation of the HrpG‐HrpX Cascade in Xanthomonas oryzae pv. oryzicola

Molecular Plant Pathology, Volume 27, Issue 8, August 2026.
GpaR directly activates hrpG and hrpX, triggering the HrpG–HrpX cascade to promote virulence in rice and induce the hypersensitive response in nonhost plants, revealing a key upstream regulator of type III secretion and pathogenicity in Xanthomonas oryzae pv. oryzicola. ABSTRACT Xanthomonas oryzae pv. oryzicola (Xoc), the causal agent of bacterial leaf

Epidemiological Markers for Citrus Canker caused by Xanthomonas citri pv. citri

International Journal of Phytopathology, 2023
Climatic factors have a significant impact on the growth and development of citrus canker disease, which is one of the biggest threats to the citrus industry caused by the bacterium Xanthomonas citri pv. citri (Xcc). The growth stage, host sensitivity, succulence, vigour, survival, rate of multiplication, pathogen dispersal direction, rate of spore ...

CitPH4 Confers Resistance to Citrus Canker by Activating Papain‐Like Cysteine Protease

Plant Biotechnology Journal, Volume 24, Issue 7, Page 4561-4576, July 2026.
ABSTRACT Citrus canker, a devastating disease caused by Xanthomonas citri subsp. citri (Xcc), poses a significant threat to global citrus production due to the high susceptibility of nearly all commercial citrus cultivars to it. Although transcription factor Citrus PH4 (CitPH4) is well known for regulating fruit acidity, its potential role in plant ...

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

Plant, Cell &Environment, Volume 49, Issue 7, Page 3500-3517, July 2026.
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.

Recombinant expression and characterization of a cysteine peptidase from Xanthomonas citri subsp citri

Genetics and Molecular Research, 2012
Xanthomonas citri subsp citri (Xac) is the bacterium responsible for citrus canker disease in citrus plants. The aim of this study was to describe the recombinant expression, purification, and characterization of a cysteine peptidase from Xac strain 306, which is a candidate for involvement in the pathogenicity of this bacterium.

CRISPR/Cas‐Mediated Gene Editing in Plant Immunity and Its Potential for the Future Development of Fungal, Oomycete, and Bacterial Pathogen‐Resistant Pulse Crops

Plant, Cell &Environment, Volume 49, Issue 7, Page 3573-3585, July 2026.
ABSTRACT Pulses provide myriad health benefits and are advantageous in an environmental context as a result of their leguminous nature. However, phytopathogenic fungi, oomycetes and bacteria pose a substantial threat to pulse production, at times leading to crop failure.
