Agricultural Biotechnology is a branch of agricultural science that uses scientific tools and methods to change plants, animals, and microorganisms, such as genetic engi- neering,molecular markers, molecular diagnostics, vac- cines and tissue culture. The field of crop biotechnology is one area of agricultural biotechnology that has seen signifi- cant advancements in recent years. These transgenic plants are superior in taste, bloom colour, growth rate, harvest size, and resistance to pests and diseases. Molecular biology, genetics, biochemistry, microbiology, and even chemical and process engineering have all been included in the relatively new field of agriculture biotech- nology. Major advancements in biotechnology over the last decade have led to the development of several efficient techniques for harnessing the potential of various bio- logical entities for the production of goods that improve people & health, the environment, and social well-being. This book provides an in-depth survey of the most recent advancements in plant tissue culture, cell and molecular biology, genetics and applied breeding, biochemistry, food processing, and other omics & technologies, all of which have contributed to the rapid growth of biotechnology. The applications of biotechnology are extensively covered in this book. In vitro propagation, encapsulation,secondary metabolite synthesis in vitro, somaclonal varia- tion and doubled haploid applications in agriculture, mo- lecular breeding, and agricultural uses of nanobiotech- nology are among topics that have been discussed.
