Our requirement for plant breeders to be successful has never been greater. However one views the forecasted numbers for future population growth we will need, in the immediate future, to be feeding, clothing and housing many more people than we do, inadequately, at present. Plant breeding represents the most valuable strategy in increasing our productivity in a way that is sustainable and environmentally sensitive. Plant breeding can rightly be considered as one of the oldest multidisciplinary subjects that is known to humans. It was practised by people who first started to carry out a settled form of agriculture. The art, as it must have been at that stage, was applied without any formal u...
Eminent researchers provide broad coverage of plant molecular biology and genetic engineering, detailing technological advances in plant cell transformation and responses. This state-of-the-art text includes coverage of molecular action of plant growth hormone, signal transduction, light mediated expression of genes, and genetic engineering of crop plants and trees.
Advances in Genetics
This book provides a comprehensive review at the biochemical and molecular level of the processes and techniques that contribute to crop improvement. General topics include a historical perspective of the advancements in crop improvement; cultivar systematics and biochemical and molecular markers in crop improvement programs; the genetics of physiological and biochemical processes affecting crop yield; the genetics of photosynthesis, chloroplast, relevant enzymes, and mutations; osmoregulation/adjustment and the production of protective compounds in relation to drought tolerance; and the biochemistry of disease resistance, including elicitors, defense response genes, their role in the production of phytoalexins and other strategies against pathogens. Other topics include quality breeding (e.g., molecular gene structure, changing individual amino acids, enhancing nutritive value of proteins) and biotechnology/genetic engineering. Geneticists, biochemists, botanists, agricultural specialists and others involved in crop improvement and breeding should consider this volume essential reading.
The subject of this volume is the reproductive biology of plants. A steadily growing interest in this field is the result of at least two factors, as pointed out with great foresight by one of the driving forces in the field, H.E Linskens (Linskens 1964): most of the food consumed by humans takes the form of plant reproductive parts, and molecular biology now provides pow erful tools for investigating and manipulating plant reproductive systems. Molecular biology and the allied discipline of biotechnology are solidly represented in the papers in this book. The editors of Angiosperm Pollen and Ovules believe that the chapters herein contain some of the most excit ing findings of contemporary ...
Air pollutants provide environmental conditions that drastically differ in many respects from those to which forest trees are naturally adapted. Leading experts in the field here consider these questions of immediate relevance arising from the changing environment: (1) Do air pollutants introduce effects of selection that differ from those known for populations that are not subject to such stress conditions? (2) If air pollutants introduce quantitatively or even qualitatively novel selective effects, which consequences might arise from the adaptation of forest tree populations to the present conditions as well as for the preservation of adaptability to future conditions? In addition to these questions, concepts for preservation of genetic resources are discussed.
In Recognition of the Forgotten Generation D. L. MULCAHyl Pollen was long believed to serve primarily a single function, that of delivering male gametes to the egge A secondary and generally overlooked value of pollen is that it serves to block the transmission of many defective alleles and gene combinations into the next generation. This latter function comes about simply because pollen tubes carrying defective haploid genotypes frequently fail to complete growth through the entire length of the style. However, the beneficial consequences of this pollen selection are diluted by the fact that the same deleterious genotypes are often transmitted through the egg at strictly mendelian frequenci...
While working in the laboratory of Professor Dr. Jacob Reinert at the Freie Universitat Berlin (1974-1976), I had the opportunity to become deeply involved in studying the intricacies of the fascinating phenomenon of somatic embryogenesis in plant cells and protoplasts. In numerous stimu lating discussions with Professor Reinert on this subject, I was fully convinced that somatic embryogenesis would become one of the most important areas of study, not only regarding basic and fundamental aspects, but also for its application in crop improvement. During the last decade, we have witnessed tremendous interest and achievements in the use of somatic embryos for the production of synthetic seeds, ...

The revolutionary progress made in this fascinating field of sexual reproduction inspired this generously illustrated volume. It includes 21 chapters written by experts, covering all aspects of the embryology of angiosperms, ranging from development, isolation, and structure of gametes to endosperm and seed development.
