Herbicide resistance has become an important constraint on modern agricultural practices. An alarming increase in weed biotypes that are resistant to herbicides has also been reported. Opportunity exists for a novel weed management technology, which is also compatible with no-till agricultural practices. Microwave heating can kill both emerged weed plants and weed seeds in the soil. When the intensity of the microwave fields is moderate, plants, which have already emerged, are susceptible to microwave treatment. If the microwave field is intense enough, very rapid volumetric heating and some thermal runaway in the plant structures cause micro-steam explosions in the plant cells, which rupture the plant structures, leading to death. Soil treatment requires significantly more energy; however, there are secondary benefits for crops growing in microwave treated soil. These include: significant reduction of the dormant weed seed bank; significant reduction of nematode populations; significant reduction of fungal populations; better availability of indigenous nitrogen for the plants; more rapid humification; and significant increases in crop growth and yield. Microwave weed management and soil treatment is not restricted by weather conditions; therefore, the technology may offer some timeliness and environmental benefits, which are yet to be quantified in a cropping system.

Endophytes are commonly known as microorganisms, mainly bacteria and fungi, which live inside plant tissues without inducing symptoms. Considering the long-lived trees, endophytes have a fundamental role in preparing their hosts to face extreme weather conditions, drought, heat, cold, and pathogen and herbivore attacks. The current knowledge clearly demonstrates the importance of endophytes in shaping the plant diversity in a forest. Endophytes have an important capacity for biocontrol of forest diseases. Considering endophyte diversity and the range of various compounds and enzymes they can produce, endophytes can be used for various biotechnological applications.

Plants come in myriads of shapes and colors, and the beauty of plants has fascinated mankind for thousands of years. Long before Mendel discovered the laws of heritab- ity and Darwin developed his theory on evolution, the affection for ornamental plants led people to select alleles that establish novel plant forms. Today, plant developmental biology tries to discover the mechanisms that control the establishment of specialized cell types, tissues, and organs from the fertilized egg during a plant's life. Although the underlying processes of cell proliferation and differentiation are similar in plants and a- mals, plants are different because their development is usually open, and its outcome is not the faithful repetition of a general plan but is strongly in?uenced by environm- tal conditions. In the last few decades, plant developmental biology has pinpointed a large number of developmental regulators and their interactions and the mechanisms that govern plant development start to emerge. In part, this progress was enabled by the advance of powerful molecular tools for a few model species, most importantly Arabidopsis. This volume of the Methods in Molecular Biology series provides a collection of protocols for many of the common experimental approaches in plant developmental bi- ogy. All chapters are written in the same format as that used in the Methods in Molecular TM Biology series. Each chapter opens with a description of the basic theory behind the method being described.

Gregor Johann Mendel continues to fascinate the general public as well as scholars, the former for his life and the latter for his achievements. "Solitude of a Humble Genius" is a two-volume biography presenting Mendel in the context of the history of biology and philosophy, and in the context of the setting in which he lived and worked. In this first volume the authors set the stage for a new interpretation of Mendel s achievements and personality. The period of Mendel s life covered by this volume is critical to understanding why he saw what other biologists, including Charles Darwin, for example, didn t. In searching for clues to Mendel s thinking, the authors discuss at length the origin of his genes; the history of the region of his birth; they also spend a day and then the four seasons of the year with his family; and finally they examine the schooling he received, as well as the cultural and political influences he was exposed to.

An indispensible part of the work is Norman Klein s artwork. In this first volume alone, it comprises nearly 80 original drawings and includes cartoons that enliven the narration, scenes from Mendel s life, portraits, and plans and drawings of the cities and buildings in which he lived, studied, and worked."

Forests and vegetation emit biogenic volatile organic compounds (BVOCs) into the atmosphere which, once oxidized, can partition into the particle phase, forming secondary organic aerosols (SOAs). This thesis reports on a unique and comprehensive analysis of the impact of BVOC emissions on atmospheric aerosols and climate. A state-of-the-art global aerosol microphysics model is used to make the first detailed assessment of the impact of BVOC emissions on aerosol microphysical properties, improving our understanding of the role of these emissions in affecting the Earth's climate. The thesis also reports on the implications for the climate impact of forests. Accounting for the climate impacts of SOAs, taken together with the carbon cycle and surface albedo effects that have been studied in previous work, increases the total warming effect of global deforestation by roughly 20%.

This volume provides a general overview of the therapeutic potential of the essential oils in cancer and highlights some promising future directions. It integrates chemistry, pharmacology, and medicine while discussing bioactive essential oils in experimental models and clinical studies of cancer. The book is a valuable resource for all engaged in the study of natural products and their synthetic derivatives, particularly for those interested in academic research and pharmaceutical and food industries dedicated in the discovery of useful agents for the therapy or prevention of cancer.

Plant molecular biology has produced an ever-increasing flood of data about genes and genomes. Evolutionary biology and systematics provides the context for synthesizing this information. This book brings together contributions from evolutionary biologists, systematists, developmental geneticists, biochemists, and others working on diverse aspects of plant biology whose work touches to varying degrees on plant molecular evolution. The book is organized in three parts, the first of which introduces broad topics in evolutionary biology and summarizes advances in plant molecular phylogenetics, with emphasis on model plant systems. The second segment presents a series of case studies of gene family evolution, while the third gives overviews of the evolution of important plant processes such as disease resistance, nodulation, hybridization, transposable elements and genome evolution, and polyploidy.

With one volume each year, this series keeps scientists and advanced students informed of the latest developments and results in all areas of the plant sciences. The present volume includes reviews on genetics, cell biology, physiology, comparative morphology, systematics, ecology, and vegetation science.

Originally published in 1913, the aim is to illustrate and describe every species, from the fern upwards, recognised as distinct by botanists and growing wild within the area adopted, and to complete the work within such moderate limits of size and cost as shall make it accessible to the public generally, so that it may serve as an independent handbook of our Northern Flora and as a work of general reference. This is a fascinating read for any botanist with much of the information still practical and useful today. Many of the earliest books, particularly those dating back to the 1900's and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

This new book shows the work done by researchers dedicated to the study of different mycorrhizas types, the fungal species associated and their distribution influenced by geographical and environmental factors among the different South American biogeographic regions. The exclusive biotic and abiotic characteristics delimit natural ecosystems with uniques biological communities, where mycorrhizologists have investigated plant symbioses in those ecosystems for decades, providing data from Venezuelan Great Savannah, Andes, Puna, Chaco, Caatinga, Monte, Atlantic Forest, Marginal Forest, Cerrado, Patagonia, Yungas, Rainforest, Andean-Patagonian Forests, and Antarctic section. In these environments, different mycorrhizal associations (arbuscular / ericoid / orchidoid / ectomycorrhizal / mycoheterotrophic) are present in herbaceous plants, shrubs, and trees. Mycorrhizal associations were studied from different researching points of view (biodiversity, biological invasions, biotic / abiotic disturbances, altitudinal variations, seasonal changes, land uses). The aim of this Book is to compile research on mycorrhizal fungi and their associations in environments of South America, throughout the synthesis of information from natural and anthropogenic related environments. The book focuses in different bioregions of South America from tropical areas to the southern cone, and it will be useful to those who work on plant-fungal interactions in different vegetation types and in agricultural lands from South America and worldwide.

Thorough and intuitive, Transgenic Plants: Methods and Protocols, Second Edition aids scientists in the continuous improvements being made for the production and analysis of transgenic plants.

Health care delivery has become institutionalized. As a result, health care organizations now have the power to determine who has access to what kind of health care and under what circumstances. They shape as well the ethics of the various health care professions. These developments have provoked controversies about what kind of obligations such health care organizations have to patients, caregivers, and society at large. In order to respond to these controversies, an account of health care organizational ethics has become necessary.
The essays in this volume:

-are drawn from an interdisciplinary group of leading scholars in this growing field;

-address the nature of health care organizational ethics, including such issues as corporate fraud and institutional moral integrity;

-cover the broad range of issues that must be addressed for a coherent discussion of organizational moral responsibility;

-cover the range of theoretical and practical issues like no other volume;

-are of interest to researchers, students and professionals working in the fields of bioethics, health care administration and management, organizational science, and business ethics.

Since the concept of allelopathy was introduced almost 100 years ago, research has led to an understanding that plants are involved in complex communicative interactions. They use a battery of different signals that convey plant-relevant information within plant individuals as well as between plants of the same species or different species. The 13 chapters of this volume discuss all these topics from an ecological perspective. Communication between plants allows them to share physiological and ecological information relevant for their survival and ?tness. It is obvious that in these very early days of ecological plant communication research we are illuminating only the 'tip of iceberg' of the communicative nature of higher plants. Nevertheless, knowledge on the identity and informative value of volatiles used by plants for communication is increasing with breath-taking speed. Among the most spectacular examples are sit- tions where plant emitters warn neighbours about a danger, increasing their innate immunity, or when herbivore-attacked plants attract the enemies of the herbivores ('cry for help' and 'plant bodyguards' concepts). It is becoming obvious that plants use not only volatile signals but also diverse water soluble molecules, in the case of plant roots, to safeguard their evolutionary success and accomplish self/non-self kin rec- nition. Importantly, as with all the examples of biocommunication, irrespective of whether signals and signs are transmitted via physical or chemical pathways, plant communication is a rule-governed and sign-mediated process.

Humans face the challenge of producing enough food to meet the demands imposed by economic, biological and agricultural factors: rising population; rising income; and an expectation of higher quality food and a more diverse diet; decreasing amount of land available for food production; lowering environmental impact of agricultural practices and preserving biodiversity.
Biotechnology is one of the most exciting and dynamic industries of our day. It offers us the possibility of reducing our dependence on intensive farming. Plant biotechnology is central to the search for effective, environmentally safe and economically sound alternatives to the use of chemical pesticides and the exhaustion of natural resources. Today, applied plant science has four overall goals: increased crop yield, improved crop quality, reducing production costs and reducing negative environmental impact. Biotechnology is proving its value in meeting these goals. It offers farmers higher yielding crops with lower costs of production and new outlets such as nutraceuticals and crop-based bio-factories. It offers the European economy the potential of high quality, knowledge based job creation and the European consumer better quality, tastier and more nutritious food. Though there is public concern of genetic engineering, those who are close to the science understand that this is the next big frontier to be crossed. The potential and opportunities offered by plant biotechnology must not be missed. We must go forward on that basis rather than turning our backs on the science.
"Phytosfere'99" provides a comprehensive overview for plant biotechnology. It combines specific scientific articles, review articles and comments from outside people on it, which is unique in European Literature.

As a member of the working group (WG) on "Temperate Zone Fruit Trees in the Tropics and Subtropics" of the International Society for Horticulture, I was aware of the lack of readily available information needed in many warm-climate locations where temperate fruit crops are grown. The founder of this WG, Frank Dennis, Jr. , was motivated to encourage knowledge transfer by sharing knowledge with many developing countries. We shared his drive and in presenting this book we believe we are doing a service to all persons interested in temperate fruits, but especially to those in tropical and subtropical countries, many of which are developing countries interested in growing these crops and lacking the knowledge needed. In this book, we have collected information covering a variety of different aspects of growing temperate fruit crops in warm climates. As this is the first time such an evaluation of these species has been done, interesting and novel aspects of tree development and fruiting are presented, with stress on elements like dormancy and irrigation that are not of such basic concern in the natural of the temperate zones. We are living in a transition age; horticultural studies habitat are changing and expertise such as can be found in the array of participants in this book is probably not going to be easily found in the future. I hope that this book will broaden our understanding of the fruiting Temperate Zone tree in general and of its adaptation to warm climates, in particular.

In the 1970s, Rolla and Alice Tryon of Harvard organized an annual fern conference at Harvard Forest every spring. The mission of the conference was to bring together researchers from across a broad spectrum of biology whose common link was that they either studied ferns per se or utilized ferns in their experiments. Talks ranged from classical pteridological subjects such as taxonomy, paleobotany and morp- logy, to experimental areas such as ecology, physiology, development, genetics, and biochemistry. For the participants, of whom I was lucky to be one, it was an int- lectually exhilarating experience. We all learned new things, and the cross fertili- tion of different subjects and research approaches led to new ideas and a better understanding of ferns as organisms. The present volume, Working with Ferns: Issues and Applications, edited by Helena Fernandez, Ashwani Kumar and Maria Angeles Revilla, carries the Harvard Forest Fern Conference philosophy into the twenty-first century. The editors have assembled a truly remarkable array of contributions dealing with fern biology. Starting with researches utilizing Ceratopteris, a fern whose speedy life cycle I discovered during my doctoral research at the Royal Botanic Gardens, Kew more than 40 years ago, and ending with a study of Pteridium aq- linum, a cosmopolitan species taxonomically revised by Professor Rolla Tryon, the papers in Working with Ferns: Issues and Applications offer a look at what is new in pteridology.
