The fields of organelle biology and plant biotechnology have now been inter-related for a century. Plant organelles have intrigued biologists since their defiance of Mendelian inheritance and their endosymbiont origins became apparent. In modern times, plant organelles are again leading the way for the creation of genetically modified crops. Several thousand proteins are imported into chloroplasts that participate in biosynthesis of fatty acids, amino acids, pigments, nucleotides and numerous metabolic pathways including photosynthesis. Thus, from green revolution to golden rice, plant organelles have played a critical role in revolutionizing agriculture. This book details not only the basic concepts and current understanding of plant organelle genetics and molecular biology but also focuses on the synergy between basic biology and biotechnology.
Biotechnology commonly abbreviated as biotech is the broad area of biology involving living systems and organisms to develop or make products, or "any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use" UN Convention on Biological Diversity , Art. For thousands of years, humankind has used biotechnology in agriculture , food production , and medicine. In the late 20th and early 21st centuries, biotechnology has expanded to include new and diverse sciences such as genomics , recombinant gene techniques, applied immunology , and development of pharmaceutical therapies and diagnostic tests. The wide concept of "biotech" or "biotechnology" encompasses a wide range of procedures for modifying living organisms according to human purposes, going back to domestication of animals, cultivation of the plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. Modern usage also includes genetic engineering as well as cell and tissue culture technologies. The American Chemical Society defines biotechnology as the application of biological organisms, systems, or processes by various industries to learning about the science of life and the improvement of the value of materials and organisms such as pharmaceuticals, crops, and livestock.
As a textbook, Molecular Biology and Biotechnology has always been immensely popular. Now in its fourth edition, it has been completely revised and updated to provide a comprehensive overview and to reflect all the latest developments in this rapidly expanding area. Written by recognised experts, the book aims to identify the impact that molecular biology has had on the development of biotechnology, with each of the nineteen chapters describing a specific subject area relevant to the subject. The impressive breadth of coverage includes areas such as plant biotechnology; food technology; vaccine development; the production of transgenic plants and animals; and the addition of an appropriate and timely new chapter devoted to bioinformatics. Presenting information in an easily assimilated form, Molecular Biology and Biotechnology makes an ideal undergraduate text. It will be of particular interest to students of biology and chemistry, as well as to scientists from outside the field requiring a rapid introduction to the subject. Jump to main content.
