Meristematic cells in plants become the many different types of cells found in a mature plant. This is achieved by a selective response to chemical signals both from neighbouring cells and distant tissues. It is these responses that shape the plant, its time of flowering, the sex of its flowers, its length of survival or progress to senescence and death. How do plants achieve this? This treatise addresses this question using well-chosen examples to illustrate the concept of target cells. The authors discuss how each cell has the ability to discriminate between different chemical signals,...

This book presents a completely novel approach to understanding aging: it explains both why aging exists in animals and reviews our current understanding of it at the biological level. Dr. Holliday argues that much research needs to be done on the cellular and molecular aspects of aging if the origin of age-related diseases is to be understood. In making this argument, the author draws on material from a wide range of disciplines, including extensive biomedical information about age-related disease in humans. This thought-provoking book will appeal to all students and researchers who are...

This fully revised edition of The Neural Crest contains the most current information about this unique structure that has a transient existence in early embryonic life. The ontogeny of the neural crest embodies the most important issues in developmental biology, as the neural crest is considered to have played a crucial role in evolution of the vertebrate phylum. This revised edition includes new data that analyze neural crest ontogeny in murine and zebrafish embryos. Additional features include coverage of advances in our understanding of neural crest cell subpopulation markers, cell lineage...

The chapters in this book are centered around the structure of tissues, an intermediate and neglected level between overt morphology and biochemistry, and will be of great interest to all those engaged in attempting to understand the principles behind plant development. The author's purpose is to predict what should be looked for on a molecular level so as to account for observable forms. Each chapter deals with a defined problem such as the role of hormones as correlative agents, tissue polarization, apical meristems and cell lineages. The final chapter develops an alternative approach to...
