Plants constantly cope with unfavourable ecosystem conditions, which often prevent them reaching their full genetic potential in terms of growth, development and productivity. This book covers plants' responses to these environmental changes, namely, the modulation of amino acids, peptides and amines to combat both biotic and abiotic stress factors. Bringing together the most recent developments, this book is an important resource for researchers and students of crop stress and plant physiology.

The early seventeenth century was a time of great literature the era of Cervantes and Shakespeare but also of international tension and heightened diplomacy. This book looks at the relations between Spain under Philip III and Philip IV and England under James I in the period 1603-1625. It examines the essential issues that established the framework for diplomatic relations between the two states, looking not only at questions of war and peace, but also of trade and piracy. Oscar Ruiz Fernandez argues that the diplomatic relationship was vital to the strategic interests of both powers and also played a highly significant role in the domestic agendas of each country. Based on Spanish and English sources and original research, this book provides, for the first time, a clear picture of diplomacy between England and Spain in the early modern era."
