Sex in animals has been known for at least ten thousand years, and this knowledge was put to good use during animal domestication in the Neolithic period. In stark contrast, sex in plants wasn't discovered until the late 17th century, long after the domestication of crop plants. Even after its discovery, the "sexual theory" continued to be hotly debated and lampooned for another 150 years, pitting the "sexualists" against the "asexualists". Why was the notion of sex in plants so contentious for so long? "Flora Unveiled" is a deep history of perceptions about plant gender and sexuality, beginning in the Ice Age and ending in the middle of the nineteenth century, with the elucidation of the complete plant life cycle. Linc and Lee Taiz show that a gender bias that plants are unisexual and female (a "one-sex model") prevented the discovery of plant sex and delayed its acceptance long after the theory was definitively proven. The book explores the various sources of this gender bias, beginning with women's role as gatherers, crop domesticators, and the first farmers. In the myths and religions of the Bronze and Iron Ages, female deities were strongly identified with flowers, trees, and agricultural abundance, and during Middle Ages and Renaissance, this tradition was assimilated into Christianity in the person of Mary. The one-sex model of plants continued into the Early Modern Period, and experienced a resurgence during the eighteenth century Enlightenment and again in the nineteenth century Romantic movement. Not until Wilhelm Hofmeister demonstrated the universality of sex in the plant kingdom was the controversy over plant sex finally laid to rest. Although "Flora Unveiled" focuses on the discovery of sex in plants, the history serves as a cautionary tale of how strongly and persistently cultural biases can impede the discovery and delay the acceptance of scientific advances.

The perception that civilization is crossing a period of Global Climatic Changes that can seriously threaten our lifestyle, along with energy security and the search for prosperity, are the main drivers that are pushing men to use more biomass as a source of energy. It will be crucial that such intent will include a large parcel of sustainability so that more renewable energy becomes available for populations. Because large amounts of energy are "hidden" in carbon polymers made by plants, notably carbohydrates, it is obvious that if technologies are developed to produce liquid fuels such as ethanol from carbohydrate polymers such as cellulose, men could significantly increase energy sustainability . This book reviews general aspects of biomass utilization for bioenergy production as well as strategies using biochemistry, molecular biology, chemistry and physics to disassemble plant cell walls. Recent discoveries of basic science under development in several laboratories in the world are reviewed by experts that have been intensively working with many aspects that will impact the development of the technology of production of cellulosic ethanol.

Jatropha curcas or Physic Nut is a small tree (bush plant) that produces fruits under tropical climate. The fruits contained seed that are ~40% oil rich. This oil is excellent for biodiesel. The bush is a now new coming crop because it may cope with harsh environmental conditions such as semi-aridity and poor land. It is considered as one alternative for climate mitigation that does not compete with arable land normally dedicated to food crop and can be used to regain degraded land or fight desertification. This bush has been considered seriously by the international community only recently (~2006-2008), but worldwide scientists did an outstanding job to drawn Jatropha out of its semi-wild status and bring it on the industrial scene. Problems remains, but we have now a comprehensive picture of this crop and almost every technological challenged were addressed. From now, the job will have to concentrate on breeding in order to domesticate this species. Therefore, it is the right time to sum up worldwide contributions in a comprehensive book with a breeding looking to improve the chance of this plant to stabilize as a crop and to fulfil with the expectations that humans invested in it. A book with this perspective will help international community to give a step on. The book will be a broad and comprehensive look on Jatropha until the details since the book is being contributed by international experts worldwide that have already published works in the international press of Science. Illustrations, tables geographic maps, GPS location, etc are added by each contributors according to the feeling they have concerning what they think their contribution should be.

Lupins have until recently remained wild or semi-domesticated species of minor interest to agriculture, although their value as a rotation crop was noted 2,000 years ago. However, with the advent of the science of genetics in the early twentieth century, full domestication of Lupinus species for use as crops was begun, by the combination of favourable genes such as those for low alkaloid content, non-shattering pods and soft seeds. As a result several lupin species have become an important part of temperate farming systems as a high protein crop for both animal and human consumption. This book gives an authoritative account of the history, distribution and taxonomy of Lupinus species and the current knowledge of all aspects of their agronomy and impact on agriculture, including breeding, genetics and biotechnology, nutrition, nitrogen fixation, transport physiology, toxins, stress responses, pests and diseases, agronomy and farming systems, composition and food uses, economic value and trade. Contributions are made by researchers in Australia and Europe who have had key roles in lupin research. The book is essential reading for botanists, agronomists, plant breeders and geneticists involved with lupins and other grain legumes or with an interest in crop domestication and evolution. It also provides important information for lecturers and students of agriculture and for professionals in the livestock and food industries.

An understanding of crop physiology and ecophysiology enables the horticulturist to manipulate a plant's metabolism towards the production of compounds that are beneficial for human health when that plant is part of the diet or the source of phytopharmaceutical compounds. The first part of the book introduces the concept of Controlled Environment Horticulture as a horticultural production technique used to maximize yields via the optimization of access to growing factors. The second part describes the use of this production technique in order to induce stress responses in the plant via the modulation of these growing factors and, importantly, the way that this manipulation induces defence reactions in the plant resulting in the production of compounds beneficial for human health. The third part provides guidance for the implementation of this knowledge in horticultural production.

How do plants, even if still buried underground, know that it's their time to bloom? What signals them to begin the challenging task of making flowers, and how do they make the variety of flower shapes, colours, and scents? What kind of instructions does the plant carry? Flowers enrich the beauty of meadows and gardens, but of course, they are not there simply to please us. Biologically, blossoms form a critical aspect of the reproductive cycle of many plants. In this book, the distinguished scientist Maxine Singer explains what we have pieced together about the genetics behind flowering. She describes in a clear and accessible account the key genes which, regulated by other genes, modulated by epigenetic effects, and responding to environmental cues, cause plants to flower at a particular time, and define the variety of flowers. The remarkably intricate processes involved in making flowers have evolved in nature alongside the pollinating birds and insects that the flowers must attract if there is to be another generation. The processes involved in flowering have only been unravelled in the past twenty years, and the implications for ensuring production of food, including fruits and seeds, are profound. This is cutting-edge science, and we have much still to learn, but the story being revealed that lies behind the flowers in our gardens, parks, and fields is proving astonishing.

The use of inducible gene expression systems is a rapidly developing area of plant molecular biological research. There is considerable interest in the use of these systems as research tools, not only because they allow expression of genes which may be, for example, developmentally lethal, but also because they allow for controlled experiments to be performed in a true isogenic background. They also have the potential to provide a means by which desired characters are expressed in field-based systems in the future.

Biological management of nutrient supply to plants is intrinsically more complex than the provision of nutrients as inorganic fertilizers. We need to know whether the nutrients released are retained or lost from the system, whether rates of decomposition can be manipulated to improve nutrient use efficiency, and how the various fractions of plant residues translate into pools of organic matter in soil. Only then can predictive models for nutrient release, plant uptake and soil organic matter dynamics be truly tested and validated. This book brings together contemporary ideas on the characterization and manipulation of plant quality and especially its role in soil organic matter formation and nutrient cycling. It contains work from the leading workers in both temperate and tropical systems. There are also contributions describing work outside decomposition in soil ecosystems, such as the work of plant biochemists and animal nutritionists, as research in these areas has provided many ideas and concepts used in plant quality analysis. A wide range of topics is covered from investigations at the molecular level through to management options for farmers in relation to optimising biological management of crop residues. The work presented in this volume is valuable to all those researching and managing the supply of nutrients to plants. It is important reading for soil scientists, plant physiologists and crop scientists.
