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.

Fungal Extracts as Biocontrol of Growth, Biofilm Formation, and Motility of Xanthomonas citri subsp. Citri [PDF]
Global Journal of Agricultural Innovation, Research & Development, 2019 For the present work, Metarhizium rileyi, a common entomopathogenic fungus, was grown in batch conditions in the absence and presence of its host, Spodoptera frugiperda, to obtain secondary metabolites with potential antimicrobial effect. The extraction of secondary metabolites was carried out by using two solvent systems for the biomass (ethyl ...

Microbiology, 2013 Xanthomonas citri subsp. citri (Xcc) develops a biofilm structure both in vitro and in vivo. Despite all the progress achieved by studies regarding biofilm formation, many of its mechanisms remain poorly understood. This work focuses on the identification of new genes involved in biofilm formation and how they are related to motility, virulence and ...

Actinomycin Derivatives: Structural Diversification and Biological Activities
ChemMedChem, Volume 21, Issue 15, 14 August 2026.Actinomycins are chromopeptide antibiotics exhibiting remarkable structural diversity and broad bioactivity. This review traces their development from naturally occurring D‐, X‐, A‐, G‐, Y‐, and Z‐type analogs to precursor‐directed, synthetic, and semisynthetic derivatives.

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 ...

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

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 ...
