For 150 years scientists at the Rothamsted Experimental Station have studied aspects of plant nitrogen nutrition and amino acid biosynthesis. This book is the result of a meeting held to mark this century and a half of work there. The papers look at the significant progress in understanding the biochemistry of amino acids recently achieved, in the light of this history of research. Leading researchers from around the world have contributed authoritative chapters on protein amino acids, non-protein amino acids, betaines, glutathione, polyamines and other secondary metabolites derived from amino acids. As well as being essential in some animals' nutrition, these compounds can have important roles in defending against herbivores, insects and disease. An understanding of these compounds can help in devising better crop protection and production methods.

Plants convert inorganic nitrogen into amino acids, the building blocks for proteins. They also make a wide range of other nitrogen compounds to help protect themselves from pests and diseases. An understanding of these compounds can therefore help in devising better crop protection and production methods. This volume contains essays by scientists who have studied aspects of plant nitrogen nutrition and amino acid biosynthesis. There are chapters on protein amino acids, nonprotein amino acids, betaines, glutathione, polyamines, and other secondary metabolites derived from amino acids. The results of these studies will be of interest to graduate students and professionals in biochemistry and botany.
