Regulation systems for stress responses in cyanobacteria

Regulation systems for stress responses in cyanobacteria The article reviews the main systems that regulate gene expression in cyanobacteria in response to various treatments: low and high temperatures, salt, hyperosmotic and oxidative stresses. The systems for perception of light are also reviewed. Functional characteristics are presented for known two-component regulatory systems, eukaryotic-type serine-threonine protein kinases, σ-subunits of RNA-polymerase, DNA-binding transcription factors. Different mechanisms of perception of stress signals are analyzed, including changes in DNA supercoiling under different stress conditions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals

Abstract

The article reviews the main systems that regulate gene expression in cyanobacteria in response to various treatments: low and high temperatures, salt, hyperosmotic and oxidative stresses. The systems for perception of light are also reviewed. Functional characteristics are presented for known two-component regulatory systems, eukaryotic-type serine-threonine protein kinases, σ-subunits of RNA-polymerase, DNA-binding transcription factors. Different mechanisms of perception of stress signals are analyzed, including changes in DNA supercoiling under different stress conditions.
