Overview

About 150 million years ago dinosaurs were disappearing from the Earth, and flowering plants were appearing. Since that time, flowering plants (angiosperms) have flourished, rapidly diversifying and spreading into virtually every landscape on the planet. Charles Darwin referred to this abrupt origin and highly accelerated rate of diversification of angiosperms an "abominable mystery".
Another great botanical mystery over the past 100 years has to do with what induces plants to make flowers. Young angiosperms don't have flowers, they make just roots, shoots and leaves. But at some point during their lifetime, they begin to make flowers. The question is: what triggers this? A major clue in solving this mystery happened about 100 years ago when scientists discovered evidence for a flower-inducing signal, produced in the leaves, that they named florigen.
Discovering the nature of florigen has taken nearly 100 years. But recently scientists have not only identified florigen but also have pieced together how it works to induce flowering.
This book is a summary of what is currently known about the biology of florigen and flowering, written by someone who has been teaching the subject to college students for nearly 30 years. It's also a book about how and why plants tell time, because this is part of the story. And, just for fun, there's some speculation based on recent scientific evidence about the origin and diversification of flowering plants.

About the Author

The author received a Ph.D. in Plant Physiology from the University of Washington, Seattle, in 1980. Since then, he has taught biology, biochemistry, botany, and plant physiology as a faculty member at Williams College (Williamstown, MA) and Montana State University (Bozeman, MT). His research interests mainly encompass plant growth and development, but he has also done research on plants growing in geothermal environments in Yellowstone National Park. He has received research funding from NSF, NASA, USDA and DOE and has published over 25 refereed papers in scientific journals and several book chapters on plant biology. He currently resides in Bellingham, Washington, and writes the occasional weblog HowPlantsWork.com.
