Heat-shock response in Archaea.
The Archaea are one of the three phylogenetic domains into which all organisms have been classified, and include extreme halophiles, extreme thermophiles and methanogens. Some of these organisms inhabit inhospitable environments on Earth, and thus have evolved stress responses to cope with the extremes of heat, pH and salinity that they encounter. Although the archaeal stress or heat-shock response bears some similarity to the heat-shock responses of other organisms, it possesses some unique features. A better understanding of this response would facilitate its exploitation in the biotechnological industries; for example, in engineering cells that exhibit an improved ability to withstand, or recover from, stress.
