Our knowledge of the microbiology of the phyllosphere, or the aerial parts of plants, has
historically lagged behind our knowledge of the microbiology of the rhizosphere, or the …

Excessive and indiscriminate use of antibiotics to treat bacterial infections has lead to the
emergence of multiple drug resistant strains. Most infectious diseases are caused by …

The most common prokaryotic signal transduction mechanisms are the one-component
systems in which a single polypeptide contains both a sensory domain and a DNA-binding …

Microorganisms are found everywhere, and they are closely associated with plants.
Because the establishment of any plant–microbe association involves chemical …

Plants support a diverse array of bacteria, including parasites, mutualists, and commensals
on and around their roots, in the vasculature, and on aerial tissues. These microbes have a …

Bacteria use small signal molecules in order to monitor their population density and
coordinate gene regulation in a process called quorum sensing. In Gram-negative bacteria …

In many γ‐proteobacteria, the conserved GacS/GacA (BarA/UvrY) two‐component system
positively controls the expression of one to five genes specifying small RNAs (sRNAs) that …

Bacteria adhere to environmental surfaces in multicellular assemblies described as biofilms.
Plant-associated bacteria interact with host tissue surfaces during pathogenesis and …

Work over the past few years has provided evidence that quorum sensing is a generic
regulatory mechanism that allows bacteria to launch a unified, coordinated response in a …

The complete genomic sequence of Pseudomonas syringae pv. syringae B728a (Pss
B728a) has been determined and is compared with that of P. syringae pv. tomato DC3000 …
