This book presents a review of some recent developments in various areas of plant biotechnology impinging on their application to improving crop productivity and product diversification. It covers genetic manipulation of major products such as carbohydrates, fatty acids, sesquiterpenes, and floriculture crops as well as discusses aspects related to biosafety, environmental release and commercial exploitation of transgenics. The progress made in developing pest-resistant transgenic plants and production of human therapeutics in plants are presented. Utility of molecular biology techniques in plant breeding, for protection of intellectual property rights/Plant Breeders' Rights, biosystematics etc. is also discussed. Research managers may find it useful in gaining a clear perspective of plant biotechnology. For teachers and students of biotechnology the book will be a useful reference.
