The Molecular and Physiological Basis of

To meet increasing demands to feed the world population while keeping the environment intact, improved methods of crop nutrition are at the forefront of recent literature. The Molecular Basis of Nutrient Use Efficiency in Crops bridges the gap between traditional agronomy and molecular biology by linking underpinning molecular mechanisms to the physiological and agronomic aspects of crop yield. Key issues relating to agriculture and food production in the 21st century will be discussed, in conjunction with future demands on crop nutrition, including changing temperature and water availability. Written by internationally recognized experts in the field, this is a must have references for those in academia as well as professionals working in this field.

Malcolm J. Hawkesford is Deputy Head of the Plant Sciences Department and Project Leader of the Nutrition Group at Rothamsted Research, UK. Peter Barraclough formerly a Group Leader in Crop Nutrition at Rothamsted Research, UK, now retired.
