Plant biotechnology is concerned with the application of the techniques of biotechnology to manipulate the characteristics of economically important plants for use in agriculture. Some of these characteristics are improved yield, disease and pest resistance, abiotic stress tolerance, etc. In recent years, various innovative methods of plant breeding have come into practice, like marker assisted selection, genetic modification, etc. Such techniques facilitate the introduction of new traits as well as control over a plant's genetic structure. This book is a valuable compilation of topics, ranging from the basic to the most complex advancements in the field of plant biotechnology. It brings forth some of the most innovative concepts and elucidates the unexplored aspects of this field. This book aims to serve as a reference to a broad spectrum of readers.
