Regulation of the desaturation of fatty acids and its role in tolerance to cold and salt stress.
The expression of cold-inducible genes is regulated by a two-component system in Synechocystis and Bacillus subtilis. The cold sensors are membrane-bound histidine kinases and it seems likely that they sense and transduce changes in the fluidity of membranes. Desaturation of fatty acids in membrane lipids has been implicated in tolerance to cold and salt stress.
