This book contains the proceedings of the International Symposium on the Mechanisms of Sexual Reproduction in Animals and Plants, where many plant and animal reproductive biologists gathered to discuss their recent progress in investigating the shared mechanisms and factors involved in sexual reproduction. This now is the first book that reviews recent progress in almost all fields of plant and animal fertilization. It was recently reported that the self-sterile mechanism of a hermaphroditic marine invertebrate (ascidian) is very similar to the self-incompatibility system in flowering plants. It was also found that a male factor expressed in the sperm cells of flowering plants is involved in gamete fusion not only of plants but also of animals and parasites. These discoveries have led to the consideration that the core mechanisms or factors involved in sexual reproduction may be shared by animals, plants and unicellular organisms. This valuable book is highly useful for reproductive biologists as well as for biological scientists outside this field in understanding the current progress of reproductive biology.
Many exciting discoveries in recent decades have contributed new knowledge to our understanding of the mechanisms that regulate various stages of plant growth and development. Such information, coupled with advances in cell and molecular biology, is fundamental to crop improvement using biotechnological approaches. Two volumes constitute the present work. The ?rst, comprising 22 chapters, commences with introductions relating to gene regulatory models for plant dev- opment and crop improvement, particularly the use of Arabidopsis as a model plant. These chapters are followed by speci?c topics that focus on different developmental aspects associated with vegetative and reproductive phases of ...
Geneticists contribute on a wide range of topics in this book, from classical genetics to the most advanced research on sequencing of the rice genome and functional genomics. They review advances in rice research and discuss molecular markers, genome organization and gene isolation.
Experts in herbicide research and development - chemists and plant physiologists -, have written 15 chapters that review all aspects pertinent to peroxidizing herbicides, compounds of topical interest since extremely low use rates ensure high environmental safety. Topics covered include structure-activity relationships, relevant patent literature, preparative methods, modes of action, greenhouse screening, laboratory assays, plant pigment biochemistry, and enzymology of the decisive target enzyme of this class of herbicides. This comprehensive review will be welcomed as a unique and timely compilation of the current status of peroxidizing herbicide research and development. It will be of interest to professional chemists and biologists in agrochemical companies, universities and agricultural colleges.
Based on their extensive experience with teaching R and statistics to applied scientists, the authors provide a beginner's guide to R. To avoid the difficulty of teaching R and statistics at the same time, statistical methods are kept to a minimum. The text covers how to download and install R, import and manage data, elementary plotting, an introduction to functions, advanced plotting, and common beginner mistakes. This book contains everything you need to know to get started with R.
Pollen grains are everywhere - in the air, in the water, in soil and in the food we eat. Pollen has direct relevance in agriculture, horticulture, plant breeding, crop improvement and biotechnology. They are further of use for montioring cytotoxic effects - by herbicides, pesticides and pollutants - testing for allergic reactions, and for basic studies on gene expression, research on differentiation and polarity. Detailed instructions of the standard techniques, which have all been tested and improvised by the authors, are given, such as collection and storage of pollen, pollen culture, germination, tests for viability, incompatibility and isolation of protoplasts. Introduced by an explanation of the principles involved, the step-by step protocols are complemented by personal notes and precautions, specifying the reagents used and various appendices on basic and specific requirements for laboratory exercises on pollen.
Advances in plant cell molecular biology have considerably increased our understanding of pollen-pistil barriers, particularly those operated by incompatibility mechanisms, and, at the same time, demonstrated the complexity and diversity of rejection systems once considered to be relatively simple. This book reviews the impressive knowledge acquired in the last century on the biology, particularly the inheritance and population genetics of self-incompatibility, and presents the new approaches to the study of the structure, function and evolution of incompatibility alleles and the analysis of cell-cell recognition and pollen rejection. The different methods now available for transforming the breeding behaviour of higher plants are also discussed.
