MBRl'OLOGl' studies the succession of transformations undergone by the fertilized E egg in the formation of a new individual. Development of the embryo is directed by morphogenetic mechanisms ruled by a strict chronology. Survival of the egg, its -transport in the genital tract, and the adaptation of the maternal organism to its presence are controlled by hormonal actions. Knowledge of these subjects is proving to be increasingly important for the medical practitioner. Such information helps to explain anatomic correlations; organ relation ships also illuminate the etiology of numerous pathologic conditions. Disturbances of prenatal development engender congenital malformations and constitute an important cause of perinatal mortality and postnatal morbidity. We are gratef'ul to numerous student.~ and colleagues whose cooperation has aided preparation of this book. THE AUTHORS. TRANSLATOR'S PREFACE Translation of this work was undertaken in order to make available in English this excellent and unusual aid for the teaching arid study of mammalian, primarily human, embryology. This hook emphasizes visual presentations. It combines the use of exceptionally clear and instructive drawings with photomicrographs and concise but complete text 111 an exposition of the dynamic aspects of development. Thus, the three volumes of this book will be of help in preparation and review for students, research workers, medical practitioners such as obstetricians and pedia tricians, and-others who are concerned with embryology. Analysis of the precise timing of various stages of human development makes it especially useful for all who are interested in the study and prevention of congenital malformations.

Under the vast umbrella of Plant Sciences resides a plethora of highly specialized fields. Botanists, agronomists, horticulturists, geneticists, and physiologists each employ a different approach to the study of plants and each for a different end goal. Yet all will find themselves in the laboratory engaging in what can broadly be termed biotechnology. Addressing a wide variety of related topics, Plant Tissue Culture, Development, and Biotechnology gives the practical and technical knowledge needed to train the next generation of plant scientists regardless of their ultimate specialization. With the detailed perspectives and hands-on training signature to the authors’ previous bestselling books, Plant Development and Biotechnology and Plant Tissue Culture Concepts and Laboratory Exercises, this book discusses relevant concepts supported by demonstrative laboratory experiments. It provides critical thinking questions, concept boxes highlighting important ideas, and procedure boxes giving precise instruction for experiments, including step-by-step procedures, such as the proper microscope use with digital photography, along with anticipated results, and a list of materials needed to perform them. Integrating traditional plant sciences with recent advances in plant tissue culture, development, and biotechnology, chapters address germplasm preservation, plant growth regulators, embryo rescue, micropropagation of roses, haploid cultures, and transformation of meristems. Going beyond the scope of a simple laboratory manual, this book also considers special topics such as copyrights, patents, legalities, trade secrets, and the business of biotechnology. Focusing on plant culture development and its applications in biotechnology across a myriad of plant science specialties, this text uses a broad range of species and practical laboratory exercises to make it useful for anyone engaged in the plant sciences.

The status of crop biotechnology before 2001 was reviewed in Transgenic Crops I-III, but recent advances in plant cell and molecular biology have prompted the need for new volumes. This volume is devoted to fruit, trees and beverage crops. It presents the current knowledge of plant biotechnology as an important tool for crop improvement and includes up-to-date methodologies.

Among the many applications of stem cell research are nervous system diseases, diabetes, heart disease, auto-immune diseases as well as Parkinson's disease, end-stage kidney disease, liver failure, cancer, spinal cord injury, multiple sclerosis and Alzheimer's disease. Stem cells are self-renewing, unspecialised cells that can give rise to multiple types all of specialised cells of the body. Stem cell research also involves complex ethical and legal considerations since they involve adult, foetal tissue and embryonic sources. This new book brings together leading research from throughout the world in this frontier field.

This book has been written to meet the needs of students for biotechnology courses at various levels of undergraduate and graduate studies. This book covers all the important aspects of plant tissue culture viz. nutrition media, micropropagation, organ culture, cell suspension culture, haploid culture, protoplast isolation and fusion, secondary metabolite production, somaclonal variation and cryopreservation. For good understanding of recombinant DNA technology, chapters on genetic material, organization of DNA in the genome and basic techniques involved in recombinant DNA technology have been added. Different aspects on rDNA technology covered gene cloning, isolation of plant genes, transposons and gene tagging, in vitro mutagenesis, PCR, molecular markers and marker assisted selection, gene transfer methods, chloroplast and mitochondrion DNA transformation, genomics and bioinformatics. Genomics covers functional and structural genomics, proteomics, metabolomics, sequencing status of different organisms and DNA chip technology. Application of biotechnology has been discussed as transgenics in crop improvement and impact of recombinant DNA technology mainly in relation to biotech crops.
