Preface This book covers analytical methods and approaches, which have led to significant advances in our understanding of seed dormancy and germination and have the potential to lead to new avenues of research. The methods detailed in this book are of value for both applied and fundamental seed research, and range from whole seed batch treatments to the analysis of tissues or even single seeds at the DNA, protein, and metabolite levels. Methods are described in detail and critical steps explained so that several of the chapters of this book can serve both as a protocol and a guideline for their adaptation and optimization to new applications or species. The viability and vigor of seeds are the very basis for sustainable agriculture and forestry, and understanding the molecular and cellular events underlying these processes will become increasingly important to many economical sectors and for species that provide the world’s food supply. Seeds are also the focus of environmental conservation efforts aimed at preserving the floral biodiversity of vanishing habitats. Understanding seedrelated processes is thus of major social, environmental, and economical concern. The main foci of seed-related research are the regulation of lifecycle transitions, such as the dormancy-to-germination and germination-to-growth transitions; seed viability, quality, and vigor are central as well, and are influenced by events that take place during seed development.
