In recent years there has been a growing awareness of the importance of reproductive biology to crop production and there has been a tremendous increase in research on reproductive structures of higher plants. Presented here is a wide information of different aspects of micro- and macrosporogenesis, pollen-stigma interaction and recognition, pollen tube growth, cytoskeleton, in vitro and in vivo gamete fusion, and incompatibility. The most advanced techniques employed in studies on reproductive biology of higher plants are described in detail.

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.

This book contains the proceedings of the International Symposium on the Mechanisms of Sexual Reproduction in Animals and Plants, where many plant and animal reproductive biologists gathered to discuss their recent progress in investigating the shared mechanisms and factors involved in sexual reproduction. This now is the first book that reviews recent progress in almost all fields of plant and animal fertilization. It was recently reported that the self-sterile mechanism of a hermaphroditic marine invertebrate (ascidian) is very similar to the self-incompatibility system in flowering plants. It was also found that a male factor expressed in the sperm cells of flowering plants is involved in gamete fusion not only of plants but also of animals and parasites. These discoveries have led to the consideration that the core mechanisms or factors involved in sexual reproduction may be shared by animals, plants and unicellular organisms. This valuable book is highly useful for reproductive biologists as well as for biological scientists outside this field in understanding the current progress of reproductive biology.

Comprising about one hundred plates this atlas documents and describes the processes concerning the sexual reproduction in higher plants. It is dividedinto three parts: - Anther Development - Pistil Development - Progamic Phase and Fertilization. The scanning, transmission electron and light micrographs are all of immaculate quality and - for the viewer's orientation - almost each plate is complemented by a scheme showing a larger area of the plant indicating the site of the section. Together with instructive texts, the often striking images provide a valuable introduction into plant reproductive cell structures for researchers and advanced students of genetics, plantbreeding and cell biology.

This collection of reviews by leading investigators examines plant reproduction and sexuality within a framework of evolutionary ecology, providing an up-to-date account of the field. The contributors discuss conceptual issues, showing the importance of sex allocation, sexual selection and inclusive fitness, and the dimensions of paternity and maternity in plants. The evolution, maintenance, and loss of self-incompatibility in plants, the nature of 'sex choice' in plants, and sex dimorphism are all explored in detail. Specific forms of biotic interactions shaping the evolution of plant reproductive strategy are discussed, and a taxonomically based review of the reproductive ecology of non-angiosperm plant groups, such as bryophytes, ferns, and algae, is presented. Together these studies focus on the complexities of plant life cycles and the distinctive reproductive biologies of these organisms, while showing the similarities between nonflowering plants and the more thoroughly documented flowering species.

As a part of plant science, plant reproduction is concerned with the study of production of new plants through asexual and sexual processes. It focuses on the crucial aspects of asexual reproduction, which include vegetative reproduction and apomixis and sexual reproduction, which include processes like meiosis and fertilization. This book presents the different concepts and methods related to the field of plant reproduction. Different approaches, evaluations and methodologies have been included in it. This textbook aims to serve as a resource guide for students and experts alike and contribute to the growth of the discipline.
