Currently, plant diseases and insect infestations are mainly controlled by the extraneous
application of pesticides. Unfortunately, the indiscriminate use of such agrochemicals can …

Bacteria of the genus Legionella are natural pathogens of amoebae that can cause a severe
pneumonia in humans called Legionnaires' Disease. Human disease results from inhalation …

Most bacterial pathogens have the remarkable ability to flourish in the external environment
and in specialized host niches. This ability requires their metabolism, physiology, and …

Small RNA regulators (sRNAs) have been identified in a wide range of bacteria and found to
play critical regulatory roles in many processes. The major families of sRNAs include true …

During stress, bacteria undergo extensive physiological transformations, many of which are
coordinated by ppGpp. Although ppGpp is best known for enhancing cellular resilience by …

The genus Legionella contains more than 50 species, of which at least 24 have been
associated with human infection. The best-characterized member of the genus, Legionella …

Like for all microbes, the goal of every pathogen is to survive and replicate. However, to
overcome the formidable defenses of their hosts, pathogens are also endowed with traits …

Legionella pneumophila is an intracellular bacterial pathogen that can cause a severe form
of pneumonia in humans, a phenotype evolved through interactions with aquatic protozoa in …

We report here the results of an analysis of the regulatory range of the GacS/GacA two‐
component system in Pseudomonas aeruginosa. Using microarrays, we identified a large …

Histone posttranslational modifications control eukaryotic gene expression and regulate
many biological processes including immunity. Pathogens alter host epigenetic control to …
