Every cell has developed mechanisms to respond to changes in its environment and to adapt its growth and metabolism to unfavorable conditions. The unicellular eukaryote yeast has long proven as a particularly useful model system for the analysis of cellular stress responses, and the completion of the yeast genome sequence has only added to its power This volume comprehensively reviews both the basic features of the yeast genral stress response and the specific adapations to different stress types (nutrient depletion, osmotic and heat shock as well as salt and oxidative stress). It includes the latest findings in the field and discusses the implications for the analysis of stress response mechanisms in higher eukaryotes as well.

Arvustused

From the reviews:









"This book is focused on the stress responses of yeasts . Each chapter is written in the form of a comprehensive review, that provides up-to-date, current status knowledge. The text of the Chapters is supported with excellent diagrams and figures that illustrate metabolic and gene regulatory pathways, and there is detailed referencing to the literature. The book is clearly targeted to those interested in fundamental understanding of cell stress ." (Graham H. Fleet, Mycopathologia, Issue 159, 2005)
