Acquisition and Evolution of Plant Pathogenesis-Associated Gene Clusters and Candidate Determinants of Tissue-Specificity in Xanthomonas
Background: Xanthomonas is a large genus of plant-associated and plant-pathogenic bacteria. Collectively, members cause diseases on over 392 plant species. Individually, they exhibit marked host- a...
Bacterial pathogenesis of plants: future challenges from a microbial perspective: Challenges in Bacterial Molecular Plant Pathology
Plant infection is a complicated process. On encountering a plant, pathogenic microorganisms must first adapt to life on the epiphytic surface, and survive long enough to initiate an infection. Res...
Comparative genomics of two Leptospira interrogans serovars reveals novel insights into physiology and pathogenesis
Leptospira species colonize a significant proportion of rodent populations worldwide and produce life-threatening infections in accidental hosts, including humans. Complete genome sequencing of Lep...
Drought Stress Predominantly Endures Arabidopsis thaliana to Pseudomonas syringae Infection
Plant responses to a combination of drought and bacterial pathogen infection, an agronomically important and altogether a new stress, are not well-studied. While occurring concurrently, these two s...
Expanding Role of Type II Secretion in Bacterial Pathogenesis and Beyond
Type II secretion (T2S) is one means by which Gram-negative pathogens secrete proteins into the extracellular milieu and/or host organisms. Based upon recent genome sequencing, it is clear that T2S...
Leaf scorch symptoms are not correlated with bacterial populations during Pierce's disease
Xylella fastidiosa (Xf) is a xylem-limited bacterium that lives as a harmless endophyte in most plant species but is pathogenic in several agriculturally important crops such as coffee, citrus, and...
Quorum-sensing regulation governs bacterial adhesion, biofilm development, and host colonization in Pantoea stewartii subspecies stewartii
The phytopathogenic bacterium Pantoea stewartii subsp. stewartii synthesizes stewartan exo/capsular polysaccharide (EPS) in a cell density-dependent manner governed by the Esal/EsaR quorum-sensing ...
Sample sequencing of a selected region of the genome of Erwinia carotovora subsp atroseptica reveals candidate phytopathogenicity genes and allows comparison with Escherichia coli
Genome sequencing is making a profound impact on microbiology. Currently, however, only one plant pathogen genome sequence is publicly available and 2 no genome-sequencing project has been initiate...
Sequence/structural analysis of xylem proteome emphasizes pathogenesis related proteins, chitinases and beta-1, 3-glucanases as key players in grapevine defense against Xylella fastidiosa
Xylella fastidiosa, the causative agent of various plant diseases including Pierce's disease in the US, and Citrus Variegated Chlorosis in Brazil, remains a continual source of concern and economic...
The Type II Secreted Lipase/Esterase LesA is a Key Virulence Factor Required for Xylella fastidiosa Pathogenesis in Grapevines
Pierce's disease (PD) of grapevines is caused by Xylella fastidiosa (Xf), a xylem-limited gamma-proteobacterium that is responsible for several economically important crop diseases. The occlusion o...
