Krishna district which derives its name from the famous river Krishna, is one of the nine districts of Coastal Andhra Pradesh and harbours a rich and varied flora. A total of 805 species of angiosperms and Pteridophytes belonging to 479 genera and 128 families have been enumerated. Introduction, past and present work on the flora of the district, general vegetation types, floristic analysis and artificial key to families are provided in the first part. The second part includes systematic enumeration.
This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.
This book provides a comprehensive and in-depth discussion on the development of herbicide resistance during the past 50 years, emphasizing the biochemical pathways of herbicide resistance in weeds. It discusses the principles of plant genetics, different methods of genetic engineering, makingof transgenic plants, various transgenic crops conferred with herbicide resistance, evolution of weed, problems subsequent to growing of transgenic crops, benefits and risks of growing transgenic crops, and management of transgenic crops. Packed with up-to-date information, the book includes relevant references, data, figures, and illustrations.
Plants have been a source of medicines and have played crucial role for human health. Despite tremendous advances in the field of synthetic drugs and antibiotics, plants continue to play a vital role in modern as well as traditional medicine across the globe. In even today, one-third of the world’s population depends on traditional medicine because of its safety features and ability to effectively cure diseases. This book presents a comprehensive guide to medicinal plants, their utility, diversity and conversation, as well as biotechnology. It is divided into four main sections, covering all aspects of research in medicinal plants: biodiversity and conservation; ethnobotany and ethnomedicine; bioactive compounds from plants and microbes; and biotechnology. All sections cover the latest advances. The book offers a valuable asset for researchers and graduate students of biotechnology, botany, microbiology and the pharmaceutical sciences. It is an equally important resource for doctors (especially those engaged in Ayurveda and allopathy); the pharmaceutical industry (for drug design and synthesis); and the agricultural sciences.
Early anthropological evidence for plant use as medicine is 60,000 years old as reported from the Neanderthal grave in Iraq. The importance of plants as medicine is further supported by archeological evidence from Asia and the Middle East. Today, around 1.4 billion people in South Asia alone have no access to modern health care, and rely instead on traditional medicine to alleviate various symptoms. On a global basis, approximately 50 to 80 thousand plant species are used either natively or as pharmaceutical derivatives for life-threatening conditions that include diabetes, hypertension and cancers. As the demand for plant-based medicine rises, there is an unmet need to investigate the quality, safety and efficacy of these herbals by the “scientific methods”. Current research on drug discovery from medicinal plants involves a multifaceted approach combining botanical, phytochemical, analytical, and molecular techniques. For instance, high throughput robotic screens have been developed by industry; it is now possible to carry out 50,000 tests per day in the search for compounds, which act on a key enzyme or a subset of receptors. This and other bioassays thus offer hope that one may eventually identify compounds for treating a variety of diseases or conditions. However, drug development from natural products is not without its problems. Frequent challenges encountered include the procurement of raw materials, the selection and implementation of appropriate high-throughput bioassays, and the scaling-up of preparative procedures. Research scientists should therefore arm themselves with the right tools and knowledge in order to harness the vast potentials of plant-based therapeutics. The main objective of Plant and Human Health is to serve as a comprehensive guide for this endeavor. Volume 1 highlights how humans from specific areas or cultures use indigenous plants. Despite technological developments, herbal drugs still occupy a preferential place in a majority of the population in the third world and have slowly taken roots as alternative medicine in the West. The integration of modern science with traditional uses of herbal drugs is important for our understanding of this ethnobotanical relationship. Volume 2 deals with the phytochemical and molecular characterization of herbal medicine. Specifically, it focuess on the secondary metabolic compounds, which afford protection against diseases. Lastly, Volume 3 discusses the physiological mechanisms by which the active ingredients of medicinal plants serve to improve human health. Together this three-volume collection intends to bridge the gap for herbalists, traditional and modern medical practitioners, and students and researchers in botany and horticulture.
Currently ethnobotany has been a subject of wide interest for research in developing and developed countries. The book has been dedicated to the doyen of Indian ethnobiology, Dr. S.K. Jain, FNA, popularly known as 'Father of Indian Ethnobotany'. The book comprises very important articles written by notable ethnobiologists/ botanists on different aspects of ethnobotany. The book would certainly be useful to the students, researchers and teachers working on various aspects of ethnobotany and helpful to various pharmaceutical industries in exploring plants for preparation of new drugs.
