Book Description
Advances in plant cell molecular biology have considerably increased our understanding of pollen-pistil barriers, particularly those operated by incompatibility mechanisms, and, at the same time, demonstrated the complexity and diversity of rejection systems once considered to be relatively simple. This book reviews the impressive knowledge acquired in the last century on the biology, particularly the inheritance and population genetics of self-incompatibility, and presents the new approaches to the study of the structure, function and evolution of incompatibility alleles and the analysis of cell-cell recognition and pollen rejection. The different methods now available for transforming the breeding behaviour of higher plants are also discussed.

Book Description
Great progress has been made in our understanding of pollen-pistil interactions and self-incompatibility (SI) in flowering plants in the last few decades. This book covers a broad spectrum of research into SI, with accounts by internationally renowned scientists. It comprises two sections: Evolution and Population Genetics of SI, Molecular and Cell Biology of SI Systems. The reader will gain an insight into the diversity and complexity of these polymorphic cell-cell recognition and rejection systems. Heteromorphic and homomorphic SI systems and our current understanding of the evolution and phylogeny of these systems, based on the most recent molecular sequence data, are covered. Further, the book presents major advances in our knowledge of the pistil and pollen S-determinants and other unlinked components involved in SI, as well as the apparently diverse cellular regulatory mechanisms utilised to ensure inhibition of “self” pollen.

Book Description
In 1960 Sir Frank Macfarlane Burnet received the Noble Prize in Physiology and Medicine. He titled his Nobel Lecture “Immunological Recognition of Self” emphasizing the central argument of immunological tolerance in “How does the vertebrate organism recognize self from nonself in this the immunological sense—and how did the capacity evolve.” The concept of self is linked to the concept of biological self identity. All organisms, from bacteria to higher animals, possess recognition systems to defend themselves from nonself. Even in the context of the limited number of metazoan phyla that have been studied in detail, we can now describe many of the alternative mechanism of immune recognition that have emerged at varying points in phylogeny. Two different arms—the innate and adaptive immune system—have emerged at different moments in evolution, and they are conceptually different. The ultimate goals of immune biology include reconstructing the molecular networks underlying immune processes.

Book Description
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.

Book Description
Many exciting discoveries in recent decades have contributed new knowledge to our understanding of the mechanisms that regulate various stages of plant growth and development. Such information, coupled with advances in cell and molecular biology, is fundamental to crop improvement using biotechnological approaches. Two volumes constitute the present work. The ?rst, comprising 22 chapters, commences with introductions relating to gene regulatory models for plant dev- opment and crop improvement, particularly the use of Arabidopsis as a model plant. These chapters are followed by speci?c topics that focus on different developmental aspects associated with vegetative and reproductive phases of the life cycle of a plant. Six chapters discuss vegetative growth and development. Their contents consider topics such as shoot branching, bud dormancy and growth, the devel- ment of roots, nodules and tubers, and senescence. The reproductive phase of plant development is in 14 chapters that present topics such as ?oral organ init- tion and the regulation of ?owering, the development of male and female gametes, pollen germination and tube growth, fertilization, fruit development and ripening, seed development, dormancy, germination, and apomixis. Male sterility and self-incompatibility are also discussed.

Book Description
This book reviews the current status of P. mume research, highlighting how the new data coming from the release of the P. mume genomes can advance science and help to solve a number of problems facing the P. mume industry. Prunus mume, which was domesticated in China more than 3,000 years ago as an ornamental plant and for its fruit, is one of the first genomes among the Prunus subfamilies of the Rosaceae family that has been sequenced. Combining the P. mume genome with available data, scientists have succeeded in reconstructing nine ancestral chromosomes of the Rosaceae family, as well as the chromosome fusion, fission and duplication history of three major subfamilies. The P. mume genome sequence adds to our understanding of Rosaceae evolution and provides an important basis for the improvement of fruit trees. This book offers an essential a guide for all those who are interested in gene discovery, comparative genomics, molecular breeding and new breeding techniques; and will be particularly useful for scientists, breeders, university students, and public sector institutes that are involved in the P. mume industry and/or Rosaceae research.

Book Description
The Genetics and Genomics of the Brassicaceae provides a review of this important family (commonly termed the mustard family, or Cruciferae). The family contains several cultivated species, including radish, rocket, watercress, wasabi and horseradish, in addition to the vegetable and oil crops of the Brassica genus. There are numerous further species with great potential for exploitation in 21st century agriculture, particularly as sources of bioactive chemicals. These opportunities are reviewed, in the context of the Brassicaceae in agriculture. More detailed descriptions are provided of the genetics of the cultivated Brassica crops, including both the species producing most of the brassica vegetable crops (B. rapa and B. oleracea) and the principal species producing oilseed crops (B. napus and B. juncea). The Brassicaceae also include important “model” plant species. Most prominent is Arabidopsis thaliana, the first plant species to have its genome sequenced. Natural genetic variation is reviewed for A. thaliana, as are the genetics of the closely related A. lyrata and of the genus Capsella. Self incompatibility is widespread in the Brassicaceae, and this subject is reviewed. Interest arising from both the commercial value of crop species of the Brassicaceae and the importance of Arabidopsis thaliana as a model species, has led to the development of numerous resources to support research. These are reviewed, including germplasm and genomic library resources, and resources for reverse genetics, metabolomics, bioinformatics and transformation. Molecular studies of the genomes of species of the Brassicaceae revealed extensive genome duplication, indicative of multiple polyploidy events during evolution. In some species, such as Brassica napus, there is evidence of multiple rounds of polyploidy during its relatively recent evolution, thus the Brassicaceae represent an excellent model system for the study of the impacts of polyploidy and the subsequent process of diploidisation, whereby the genome stabilises. Sequence-level characterization of the genomes of Arabidopsis thaliana and Brassica rapa are presented, along with summaries of comparative studies conducted at both linkage map and sequence level, and analysis of the structural and functional evolution of resynthesised polyploids, along with a description of the phylogeny and karyotype evolution of the Brassicaceae. Finally, some perspectives of the editors are presented. These focus upon the Brassicaceae species as models for studying genome evolution following polyploidy, the impact of advances in genome sequencing technology, prospects for future transcriptome analysis and upcoming model systems.

Book Description
Successful reproduction is the basis not only for the stability of the species in their natural habitat but also for productivity of our crop plants. Therefore, knowledge on reproductive ecology of wild and cultivated plants is important for effective management of our dwindling biodiversity and for the sustainability and improvement of the yield in crop species. Conservation and management of our plant diversity is going to be a major challenge in the coming decades, particularly in the tropical countries which are rich in biodiversity. Reproductive failure is the main driver for pushing a large number of tropical species to vulnerable category. Available data on reproductive ecology on tropical species is very limited and there is an urgent need to initiate research on these lines. A major limitation for the beginners to take up research is the absence of simple concise work manuals that provide step-wise procedures to study all aspects of reproductive ecology. The Manual fills this void. Over 60 protocols described in the manual cover the whole spectrum of reproductive ecology - study sites and species, phenology, floral morphology and sexuality, pollen and pistil biology, pollination ecology, breeding system, seed biology, seed dispersal and seedling recruitment. Each chapter gives a concise conceptual account of the topic before describing the protocols. The Manual caters to researchers, teachers and students who are interested in any aspect of reproductive ecology of flowering plants -- botanists, ecologists, agri-horticulturists, foresters, entomologists, plant breeders and conservation biologists.
