Within-host adaptation of a foliar pathogen, Xanthomonas, on pepper in presence of quantitative resistance and ozone stress

This study examines how elevated ozone stress affects the eco-evolutionary dynamics of Xanthomonas perforans on resistant and susceptible pepper cultivars, revealing increased disease severity and pathogen population heterogeneity.

Biotic and abiotic stress distinctly drive the phyllosphere microbial community structure

The paper examines how biotic and abiotic stresses affect phyllosphere microbial communities in pepper plants, finding that elevated ozone alters microbial structure in resistant cultivars but not susceptible ones, and combined stress mimics pathogen effects.

Transcriptome profiling of type VI secretion system core gene tssM mutant of Xanthomonas perforans highlights regulators controlling diverse functions ranging from virulence to metabolism

This study profiles the transcriptome of a T6SS core gene mutant in Xanthomonas perforans to identify regulators affecting virulence, metabolism, and other functions.

Genetic and functional diversity help explain pathogenic, weakly pathogenic, and commensal lifestyles in the genus Xanthomonas

This study examines the genetic and functional diversity of Xanthomonas strains to understand their pathogenic, weakly pathogenic, and commensal lifestyles through genomic analysis and phylogenetic relationships.

Influence of co-occurring weakly pathogenic bacterial species on bacterial spot disease dynamics on tomato

This study examines how co-infection with weakly pathogenic bacteria affects disease severity and population dynamics of Xanthomonas perforans on tomato.

Complete functional analysis of type IV pilus components of a reemergent plant pathogen reveals neofunctionalization of paralog genes

The paper functionally analyzes type IV pilus components in Xylella fastidiosa, revealing neofunctionalization of paralog genes and identifying FimT3 as a DNA receptor essential for natural competence.

Genome shuffling in a globalized bacterial plant pathogen: Recombination-mediated evolution in Xanthomonas euvesicatoria and X. perforans

The paper shows recombination between Xanthomonas species generates new pathogenic lineages with unique virulence factors, affecting disease management.
