Biotechnology can be broadly defined as "using organisms or their products for commercial purposes." As such, (traditional) biotechnology has been practices since he beginning of records history. It has been used to bake bread, brew alcoholic beverages, and breed food crops or domestic animals. But recent developments in molecular biology have given biotechnology new meaning, new prominence, and new potential. It is (modern) biotechnology that has captured the attention of the public. Modern biotechnology can have a dramatic effect on the world economy and society. Biotechnology is the culmination of more than 8,000 years of human experience using live organisms and the process of fermentation to make useful products. It can be viewed as a group of useful, enabling technologies with wide and diverse applications in the industry, commerce and environment. The present book "Biotechnological Applications in Environment and Agricultural" incorporates review and research articles on various aspects of plant biotechnology. This book will be useful to biotechnologists, agriculture, scientists, botanists, plant breeders, researchers, teachers and students of plant sciences.
