1. Black holes, antivirulence genes, and gene inactivation in the evolution of bacterial pathogens

Author:
Maurelli, Anthony T.

Subject:
ancestry; bacteria; evolution; gene deletion; gene expression; genetic traits; horizontal gene transfer; lifestyle; multigene family; pathogenicity islands; pathogens; plasmids; point mutation; virulence
Abstract:
... The evolution of bacterial pathogens from nonpathogenic ancestors is marked principally by the acquisition of virulence gene clusters on plasmids and pathogenicity islands via horizontal gene transfer. The flip side of this evolutionary force is the equally important adaptation of the newly minted pathogen to its new host niche. Pathoadaptive mutations take the form of modification of gene express ...

Abstract:
... Dermatophytes are the most common infectious agents responsible for superficial mycosis in humans and animals. Various species in this group of fungi show overlapping characteristics. We investigated the possibility that closely related dermatophyte species with different behaviours secrete distinct proteins when grown in the same culture medium. Protein patterns from culture filtrates of several ...

3. The role of the omega subunit of RNA polymerase in expression of the relA gene in Escherichia coli

FEMS microbiology letters 2007 v.267 no.1 pp. 51-55
ISSN:

Subject:
messenger RNA; starvation; stress response; DNA microarrays; gene expression; ribosomal proteins; operon; DNA-directed RNA polymerase; Escherichia coli
Abstract:
... The rpoZ gene for the omega subunit of Escherichia coli RNA polymerase constitutes single operon with the spoT gene, which is responsible for the maintenance of stringent response under nutrient starvation conditions. To identify the physiological role of the omega subunit, we compared the gene expression profile of wild-type Escherichia coli with that of an rpoZ deleted strain by microarray analy ...
