For centuries, humankind has made improvements to crop plants through selective breeding and hybridization - the controlled pollination of plants. Unlike traditional plant breeding, which involves the crossing of hundreds or thousands of genes, plant biotechnology allows for the transfer of only one or a few desirable genes. This more precise science allows plant breeders to develop crops with specific beneficial traits and without undesirable traits. All over the world, plant biotechnology has largely been acknowledged as a key strategy for achieving food security and sustainable agriculture. Because new agricultural technologies are increasingly complex, knowledge intensive, expensive, and location specific, clear priorities need to be established. This book is an attempt to deal with all the topics in-depth and to find out the molecular aspects of different processes in cultured plant cells, so as to exploit them for the benefit of plant biotechnology. This book will be highly beneficial to students, teachers and research workers in the field of plant biotechnology, agriculture and plant science.
