Efforts to increase efficient nutrient use by crops are of growing
importance as the global demand for food, fibre and fuel increases
and competition for resources intensifies. The Molecular and
Physiological Basis of Nutrient Use Efficiency in Crops
provides both a timely summary of the latest advances in the field
as well as anticipating directions for future research.
The Molecular and Physiological Basis of Nutrient Use
Efficiency in Crops bridges the gap between agronomic practice
and molecular biology by linking underpinning molecular mechanisms
to the physiological and agronomic aspects of crop yield. These
chapters provide an understanding of molecular and physiological
mechanisms that will allow researchers to continue to target and
improve complex traits for crop improvement.
Written by leading international researchers, The Molecular
and Physiological Basis of Nutrient Use Efficiency in Crops
will be an essential resource for the crop science community for
years to come.
Special Features:
* coalesces current knowledge in the areas of efficient
acquisition and utilization of nutrients by crop plants with
emphasis on modern developments
* addresses future directions in crop nutrition in the light of
changing climate patterns including temperature and water
availability
* bridges the gap between traditional agronomy and molecular
biology with focus on underpinning molecular mechanisms and their
effects on crop yield
* includes contributions from a leading team of global experts in
both research and practical settings
