Book Description
The IUCN/SSC Cycad ACtion Plan brings together the best available information on this ancient and fascinating group of plants. Cycads were a dominant part of the earth's flora during the age of the dinosaurs and many species were common even in more recent times. However, many of the 297 species and subspecies dealt with in the Cycad Action Plan have been badly affected by habitat destruction and plant collecting within the last century. As a result, more than half the known species are now classified as threatened, and the cycads stand out as one of the most threatened groups of plants in this world.The Action Plan provides an overview of all the cycads and the threats to their survival. This is followed by separate assessments for the four broad regions where cycads now occur, namely Africa and the Indian Ocean Islands, Australia, Asia, and the New World. Trade in cycads has had a substantial impact on wild cycad populations and there is a separate chapter on trade and the effectiveness of control measures such as CITES. In addition, with so many species facing extinction in the wild, garden collections have become increasingly important and we have assessed the global status of cycad collections.Finally, the Cycad Action Plan presents a set of objectives and actions to reduce the threat to cycads in the wild and to provide ex situ conservation for those that almost certainly will become extinct in the wild. Wherever possible, we have tried to identify and build on innovative projects, such as community-based nurseries, and to link cycad consideration with other global and local initiatives such as the conservation of biodiversity hotspots.

Book Description
This volume presents the current state of our knowledge of the classification of the approximately 300 species of cycads. It includes contributions from leading researchers from Australia, China, Italy, Mexico, South Africa, Thailand and the USA. It has been developed from papers presented at a workshop held in 2002 at the Montgomery Botanical Center. The book provides guidelines for the designation of species, species boundaries and species groupings, thus clarifying what has been a confused area of research.

Book Description
Use of and trade in wildlife is a fact of life for human society around the globe. Article IV of the CITES Convention requires that exporting countries restrict trade in Appendix II species to levels that are not detrimental either to species? survival, or to their role within the ecosystems in which they occur (known as the ?non-detriment finding?). Based on two workshops convened by IUCN to develop some pragmatic assistance for Scientific Authorities, this publication presents the background to the development of the non-detriment finding checklist and explains how the checklist itself is designed to work, in the hope that Scientific Authority staff will take and develop the parts of the approach that they find useful.

Book Description
This book highlights the rapidly expanding horizons of Plant Sciences. The conventional aspects of Botany remain the backbone of this subject, but the growing population and environmental compulsions urge man to explore new avenues to tackle the problems of society. Most of these areas, which are interdisciplinary in nature and provide new and better solutions, are pursued vigourously by researchers in Plant Sciences. Medicinal plants including Nutraceuticals, Biofuels, Natural Dyes, Biofertilisers, Biopesticides, Plant propagation methods including Tissue culture, Plant Genomics, Proteomics, Climate change and Remote sensing techniques inclusive of GIS are some of the such emerging areas focused in this book. The present book contains a good number of scien-tific articles penned by expert researchers in all these fields. Since researches in these areas are pursued in many of the Research centres and Universities, this book will be a valuable and essential reference book for one and all who are interested in these subjects.

Book Description
This volume offers a much-needed compilation of essential reviews on diverse aspects of plant biology, written by eminent botanists. These reviews effectively cover a wide range of aspects of plant biology that have contemporary relevance. At the same time they integrate classical morphology with molecular biology, physiology with pattern formation, growth with genomics, development with morphogenesis, and classical crop-improvement techniques with modern breeding methodologies. Classical botany has been transformed into cutting-edge plant biology, thus providing the theoretical basis for plant biotechnology. It goes without saying that biotechnology has emerged as a powerful discipline of Biology in the last three decades. Biotechnological tools, techniques and information, used in combination with appropriate planning and execution, have already contributed significantly to economic growth and development. It is estimated that in the next decade or two, products and processes made possible by biotechnology will account for over 60% of worldwide commerce and output. There is, therefore, a need to arrive at a general understanding and common approach to issues related to the nature, possession, conservation and use of biodiversity, as it provides the raw material for biotechnology. More than 90% of the total requirements for the biotechnology industry are contributed by plants and microbes, in terms of goods and services. There are however substantial plant and microbial resources that are waiting for biotechnological exploitation in the near future through effective bioprospection. In order to exploit plants and microbes for their useful products and processes, we need to first understand their basic structure, organization, growth and development, cellular process and overall biology. We also need to identify and develop strategies to improve the productivity of plants. In view of the above, in this two-volume book on plant biology and biotechnology, the first volume is devoted to various aspects of plant biology and crop improvement. It includes 33 chapters contributed by 50 researchers, each of which is an expert in his/her own field of research. The book begins with an introductory chapter that gives a lucid account on the past, present and future of plant biology, thereby providing a perfect historical foundation for the chapters that follow. Four chapters are devoted to details on the structural and developmental aspects of the structures of plants and their principal organs. These chapters provide the molecular biological basis for the regulation of morphogenesis of the form of plants and their organs, involving control at the cellular and tissue levels. Details on biodiversity, the basic raw material for biotechnology, are discussed in a separate chapter, in which emphasis is placed on the genetic, species and ecosystem diversities and their conservation. Since fungi and other microbes form an important component of the overall biodiversity, special attention is paid to the treatment of fungi and other microbes in this volume. Four chapters respectively deal with an overview of fungi, arbuscularmycorrhizae and their relation to the sustenance of plant wealth, diversity and practical applications of mushrooms, and lichens (associated with a photobiont). Microbial endosymbionts associated with plants and phosphate solubilizing microbes in the rhizosphere of plants are exhaustively treated in two separate chapters. The reproductive strategies of bryophytes and an overview on Cycads form the subject matter of another two chapters, thus fulfilling the need to deal with the non-flowering Embryophyte group of plants. Angiosperms, the most important group of plants from a biotechnological perspective, are examined exhaustively in this volume. The chapters on angiosperms provide an overview and cover the genetic basis of flowers development, pre-and post-fertilization reproductive growth and development, seed biology and technology, plant secondary metabolism, photosynthesis, and plant volatile chemicals. A special effort has been made to include important topics on crop improvement in this volume. The importance of pollination services, apomixes, male sterility, induced mutations, polyploidy and climate changes is discussed, each in a separate chapter. Microalgalnutra-pharmaceuticals, vegetable-oil-based nutraceuticals and the importance of alien crop resources and underutilized crops for food and nutritional security form the topics of three other chapters in this volume. There is also a special chapter on the applications of remote sensing in the plant sciences, which also provides information on biodiversity distribution. The editors of this volume believe the wide range of basic topics on plant biology that have great relevance in biotechnology covered will be of great interest to students, researchers and teachers of botany and plant biotechnology alike.
