Summary

Intended for undergraduate and graduate courses in plant development, this book explains how the cells of a plant acquire and maintain their specific fates. Plant development is a continuous process occurring throughout the life cycle, with similar regulatory mechanisms acting at different stages and in different parts of the plant. Rather than focussing on the life cycle, the book is structured around these underlying mechanisms, using case studies to provide students with a framework to understand the many factors, both environmental and endogenous, that combine to regulate development and generate the enormous diversity of plant forms. New approach to the study of plant development and a refreshing look at this fast-moving area. Authors focus their discussion on the basic mechanisms which underpin plant development, tackling the fundamental question of how a single cell becomes a complex flowering plant from a cellular perspective. An up-to-date, modern text in plant development for advanced level undergraduates and postgraduates in plant science. Thought-provoking treatment of a difficult subject, the text will satisfy the needs of advanced level undergraduates and postgraduates in plant science. Experimental case studies throughout.
