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.
