Plant Pathogenic Bacteria Studies

The periplasmic substrate-binding protein ThuE is required for sucrose uptake and multiplication of Pseudomonas syringae pv. tomato DC3000 in tomato leaves

Mobile genetic elements accompany the emergence of clonal crop lineages from weed-associated populations of Xanthomonas campestris

The paper analyzes Xanthomonas campestris strains from weed and crop hosts to show that mobile genetic elements accompany the emergence of clonal crop lineages and are present in diverse weed-associated strains.

Lipopolysaccharide Precursor Mutants Disrupt Unipolar Polysaccharide Adhesin Synthesis and Cell Surface Functions in Agrobacterium tumefaciens

This study identifies rfbA and rfbD genes critical for UPPGalN biosynthesis in Agrobacterium tumefaciens, revealing their role in cell surface functions, motility, and biofilm formation.

First Report of Soft Rot Caused by Pectobacterium brasiliense on Summer Squash in Mississippi, USA

The paper identifies Pectobacterium brasiliense as a new pathogen causing soft rot in summer squash in Mississippi using phenotypic and molecular methods.

An infection assay recapitulating Xanthomonas translucens pv. translucens natural entry into barley hydathodes

This study establishes a protocol for hydathode infection by Xtt in barley, causing bacterial blight symptoms and mimicking natural infection.

Mutation in Ralstonia pseudosolanacearum F1C1 cytochrome p450 homologue impairs virulence through root but not through shoot of tomato plants

Contrasting gene gain and loss shape metabolic diversification in the Ralstonia solanacearum species complex

The paper identifies gene gain and loss mechanisms shaping metabolic diversity in Ralstonia solanacearum by analyzing genomic data and phylogenomics.
