Description
Book SynopsisThis book provides students and researchers with a clearly written, well-structured whole plant physiology guide. Early in the text, it delivers essential information on molecular and cellular processes so readers can understand how theses processes are integrated into the development and function of the plant at whole-plant level.
Trade Review"Martin Hodson and John Bryant have written the most captivating and elementary textbook on modern plant biology. It might be read from cover to cover by anyone seeking an introduction to the subject, but seems especially suited to high school, undergraduate and vocational courses." (Expl Agric, 1 January 2013)
Named CHOICE Outstanding Title for 2012
“Students who are new to plant science will be quite well served, as will graduate students and others needing to develop fuller understandings and perspectives on their research. Summing Up: Highly recommended. Lower-division undergraduates through researchers/faculty.” (Choice, 1 November 2012)
