Book excerpt: The purpose of this book is to present classical plant development in modern, molecular-genetic terms. The study of plant development is rapidly changing as plant genome projects uncover a multitude of new genes. This book provides a framework for integrating gene discovery and genome analysis into the context of plant development. Molecular Genetics of Plant Development is designed to be used as a text-book for upper-division or graduate courses in plant development. The book will also serve as a reference book for scientists in the field of plant molecular biology or plant molecular genetics. The book is also useful for general development courses in which both animal and plant development are presented.
