Cryptococcus neoformans encounters a low oxygen environment when it enters the human
host. Here, we show that the conserved Ras1 (a small GTPase) and Cdc24 (the guanine …

The environmental pathogen Cryptococcus neoformans claims over 180,000 lives each
year. Survival of this basidiomycete at host CO2 concentrations has only recently been …

Bacterial stress responses provide them the opportunity to survive hostile environments,
proliferate and potentially cause diseases in humans and animals. The way in which …

Burkholderia cenocepacia J2315 is a highly virulent and epidemic clinical isolate of the B.
cepacia complex (Bcc), a group of bacteria that have emerged as important pathogens to …

In the gammaproteobacteria the RpoH regulon is often equated with the stress response, as
the regulon contains many of the genes that encode what have been termed heat shock …

Oenococcus oeni is a lactic acid bacterium responsible for malolactic fermentation of wine.
While many stress response mechanisms implemented by O. oeni during wine adaptation …

Across lower eukaryotes, the transcription factor Crz1 is dephosphorylated by calcineurin,
which facilitates Crz1 translocation to the nucleus to regulate gene expression. In the fungal …

The unicellular cyanobacterium Synechococcus sp. strains PCC6301 and PCC7942 have
two homologous genes, rbp1 and rbp2, encoding small RNA-binding proteins, Rbp1 and …

MrpC, a member of the CRP/Fnr superfamily of transcriptional regulators, plays a key role in
coordination of the multicellular developmental program in Myxococcus xanthus. Previous …

Erwinia amylovora is a plant-pathogenic bacterium that causes fire blight disease in many
economically important plants, including apples and pears. This bacterium produces three …
