The Phytochemical Society of North America (PSNA) is a nonprofit scientific organization with membership open to those interested in plant biochemistry, phytochemistry, and the role of plant substances in related disciplines. The PSNA exists to encourage and stimulate research in the chemistry and biochemistry of plant constituents, their effects upon plant and animal physiology and pathology, and their industrial importance and utilization. Annual meetings featuring symposium topics of current general interest and contributed papers by conference participants are held throughout Canada, the United States, and Mexico. PSNA meetings provide participants with exposure to cutting-edge research presented by prominent international scientists, but remain intimate enough to allow interaction and collegiality. Recent meetings were previously held jointly with the American Society of Pharmacognasy in St. Pete Beach, FL USA (2010), or held at Towson University, Maryland, USA (2009) and the 50th Anniversary Meeting of the PSNA at the Fairmont Orchid, Waikaloa, Hawai’i USA (2011). Information about the PSNA, can be found at www.psna-online.org.

The major function of chloroplasts in green plants and algae is oxygenic photosynthesis. Further, chloroplasts manufacture essential metabolites and phytohormones. Because of the extensive interconnection with cellular metabolic and regulatory networks, development of the organelle and the organism are coordinately regulated. Conversion of proplastids to chloroplasts is associated with the development of the entire organism, and dismantling of chloroplasts during the chloroplast-to-gerontoplast transition is coupled to senescence, the terminal phase of development. The availability of genomic tools of model plants, especially those of Arabidopsis, have allowed us to understand many complex problems associated with organelle biogenesis and senescence. Twenty-eight chapters in this book provide updated information on chloroplast development. The dynamic nature of plastid genome expression, regulation, and stability during development have been critically reviewed. In addition, authors describe how the development of emerging techniques and tools of bioinformatics, as well as rapid progress in plant molecular biology, have significantly expanded our knowledge in the area of biogenesis of the chloroplast. The book reviews the current literature on the coordinated synthesis of lipids, pigments and proteins, trafficking of the essential components, the assembly and the regulation of the protein complexes in the thylakoids as well as of the CO2-fixing enzyme Rubisco. The book provides information on genetically programmed leaf senescence and regulated disassembly of the organellar complexes during chloroplast to gerontoplast transformation. The book also deals with the response of the developing chloroplast to environmental signals through modifications and adaptation. This book was designed for those interested in plastid biology, plant development and photosynthesis, but will also be of general interest to plant biologists. dy>.

Allelopathy is an ecological phenomenon by which plants release organic chemicals (allelochemicals) into the environment influencing the growth and survival of other organisms. In this book, leading scientists in the field synthesize latest developments in allelopathy research with a special emphasis on its application in sustainable agriculture. The following topics are highlighted: Ecological implications, such as the role of allelopathy during the invasion of alien plant species; regional experiences with the application of allelopathy in agricultural systems and pest management; the use of microscopy for modeling allelopathy; allelopathy and abiotic stress tolerance; host allelopathy and arbuscular mycorrhizal fungi; allelopathic interaction with plant nutrition; and the molecular mechanisms of allelopathy. This book is an invaluable source of information for scientists, teachers and advanced students in the fields of plant physiology, agriculture, ecology, environmental sciences, and molecular biology.  .

The importance of the plant growth regulator auxin for plant growth has long been recognized, even before the discovery of its chemical structures in the early 20th century. Physiological studies in the decades since have demonstrated that auxin is unidirectionally transported in plants, a process dubbed polar auxin transport. It is the polar auxin transport process that generates a local auxin concentration gradient and regulates a broad array of physiological and developmental processes. The discoveries of auxin transport carrier proteins that mediate auxin influx into and efflux out of transport-competent cells and auxin receptor proteins for auxin signaling in the last few decades represent significant milestones in auxin research and open up opportunities to probe the cellular and molecular processes that regulate auxin transport and integrate environmental cues with signaling processes. Remarkably, components of the polar auxin transport machinery are present in both lower plants such as mosses and higher plants including monocots and eudicots, illustrating the key role of polar auxin transport in plant evolution.  This book highlights topics ranging from physiological and genetic studies of polar auxin transport in plant development, to growth responses to the environment and plant-microbe interactions, to hormonal cross-talks with various cellular and molecular regulatory processes essential for polar auxin transport.

This reference work provides a wealth of information regarding medicinal plants and phytochemicals. It is addressed both to researchers and teachers. The handbook describes phytochemicals, which, by the strictest definition, are chemicals that are produced by plants. During the last decades, more and more groups became actively involved in exploring plants for useful metabolites that lead to the identification of several useful curative agents and many promising molecules to fight and/or prevent diseases, including carcinogenesis and stroke. But when we talk about phytochemicals, there are also medicinal plants where not a single molecule is responsible for the observed properties. This reference work therefore reviews and compiles the information on both these aspects. The volumes contain contributions on phytochemicals and herbal extracts. A large number of natural products obtained from plants and microorganisms is used in cosmetic, drug, flavor and fragrance industries. For this compilation, a range of the most important medicinal herbs and phytochemicals were selected and are described by the recognized authors in the field. The present reference work encompasses the information about well established phytochemicals, biology and biotechnology of medicinal plants or their products, their biosynthesis, novel production strategies, demand and uses, metabolism and bioavailability. There is a surge of information published in recent years on herbal medicine and their pharmacologic effects with single books available on varied subjects. However, all this information is widespread and difficult to overview. Researchers who wish to keep a pace with the rapidly developing field of natural products can now consult this newly compiled handbook to find all information about bioactive molecules and medicinal plants thoroughly compiled in one place!
