Stress Responses of Photosynthetic Organisms Molecular Mechanisms and Molecular Regulations

About this book

Through the analysis of transgenic plants and cyanobacteria, the volume clarifies a number of molecular mechanisms by which plants acclimate to environmental variations, and the factors that govern recovery from stress-induced damage, especially with respect to the photosynthetic apparatus.
