Description / Table of Contents:
Since photosynthetic performance is a fundamental determinant of yield in the vast majority of crops, an understanding of the factors limiting photosynthetic productivity has a crucial role to play in crop improvement programmes. Photosynthesis, unlike the majority of physiological processes in plants, has been the subject of extensive studies at the molecular level for many years. This reductionist approach has resulted in the development of an impressive and detailed understanding of the mechanisms of light capture, energy transduction and carbohydrate biosynthesis, processes that are clearly central to the success of the plant and the productivity of crops. This volume examines in the widest context the factors determining the photosynthetic performance of crops. The emphasis throughout the book is on the setting for photosynthesis rather than the fundamental process itself. The book will prove useful to a wide range of plant scientists, and will encourage a more rapid integration of disciplines in the quest to understand and improve the productivity of crops by the procedures of classical breeding and genetic manipulation.
