The subject of this volume is the reproductive biology of plants. A steadily growing interest in this field is the result of at least two factors, as pointed out with great foresight by one of the driving forces in the field, H.E Linskens (Linskens 1964): most of the food consumed by humans takes the form of plant reproductive parts, and molecular biology now provides pow erful tools for investigating and manipulating plant reproductive systems. Molecular biology and the allied discipline of biotechnology are solidly represented in the papers in this book. The editors of Angiosperm Pollen and Ovules believe that the chapters herein contain some of the most excit ing findings of contemporary biology, and hope that the readers of this book will share their enthusiasm. The editors express sincere and grateful thanks for help from Carla Frova, Enrico Pe, and especially to Giorgio Binelli, all of the University of Milan. Without these three tireless and enthusiastic individuals it would not have been possible to maintain the apparently effortless proceeding of this congress. We thank also the organizing committee and the organizations that generously provided financial support (both listed below). Finally, we extend thanks to M. Cresti, D. Charlesworth, D. Hess, E Hoekstra, R. Bruce Knox, J.P. Mascarenhas, M.E. Nasrallah, P.L. Pfahler, A. Snow, and M.T.M. Willemse for chairing sessions.

Sexual reproduction is the predominant mode of perpetuation for flowering plant species. Investigating the reproductive strategies of plants has grown to become a vast area of research and, in crop plants, covers events from flowering to fruit and seed development; in wild species, it extends up to seed dispersal and seedling recruitment. Thus, reproduction determines the extent of yield in crop plants and, in wild plants, also determines the efficacy of recruiting new adults to the population, making this field important both from fundamental and applied plant biology perspectives. Moreover, in light of the growing concerns regarding food and nutritional security for the growing population and preserving biological diversity, reproductive biology of flowering plants has acquired special significance. Extensive studies on various facets of reproduction are being carried out around the world. However, these studies are scattered across research journals and reviews from diverse areas of biology. The present volume covers the whole spectrum of reproductive ecology, from phenology and floral biology, to sexuality and pollination biology/ecology including floral rewards, breeding systems, apomixis and seed dispersal. In turn, transgene flow, its biosafety and mitigation approaches, and the ‘global pollinator crisis’, which has become a major international concern in light of the urgent need to sustain crop yield and biodiversity, are discussed in detail. Given its scope, the book offers a valuable resource for students, teachers and researchers of botany, zoology, ecology, agriculture and forestry, as well as conservation biologists.

This book is designed to introduce the basics of different aspects of the biology of reproduction in a concise and coherent manner. The book aims to equip students with the fundamentals of the biology of reproduction and also update them with the most recent advances in the field of reproduction. The book has been organized into 16 chapters that introduce and explain different aspects in a stimulating manner. Each chapter is supplemented with a summary and relevant illustrations. A glossary has been added to help the students to understand some important scientific terms. The book offers comprehensive coverage of the important topics including: Flower structure and development Development and structure of male and female gametophytes Pollination biology, fertilization and self-incompatibility Endosperm, embryo and polyembryony Apomixis and seed biology A separate topic on experimental plant reproductive biology (experimental embryology) has been provided, which includes basics of cell, tissue and organ culture, anther culture, pollen culture, flower, ovary, ovule culture, embryo culture, somatic embryogenesis, synthetic seeds, protoplast culture and other aspects of plant biotechnology. The book aims to cater to the needs of the advanced undergraduate and post-graduate students in Botany, Forestry, Agriculture and related fields.

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.

Pollination Biology reviews the state of knowledge in the field of pollination biology. The book begins by tracing the historical trends in pollination research and the development of the two styles of pollination biology. This is followed by separate chapters on the evolution of the angiosperms; the evolution of plant-breeding systems; the geographical correlations between breeding habit, climate, and mode of pollen transfer; and sexual selection in plants. Subsequent chapters examine the process of sexual selection through gametic competition in Geranium maculatum; the effects of different gene movement patterns on plant population structure; the foraging behavior of pollinators; adaptive nature of floral traits; and competitive interactions among flowering plants for pollinators. The book is designed to provide useful material for advanced undergraduate and graduate students wishing to familiarize themselves with modern pollination biology and also to provide new insights into specific problems for those already engaged in pollination research. The book is intended to be used for both teaching and research.

In Recognition of the Forgotten Generation D. L. MULCAHyl Pollen was long believed to serve primarily a single function, that of delivering male gametes to the egge A secondary and generally overlooked value of pollen is that it serves to block the transmission of many defective alleles and gene combinations into the next generation. This latter function comes about simply because pollen tubes carrying defective haploid genotypes frequently fail to complete growth through the entire length of the style. However, the beneficial consequences of this pollen selection are diluted by the fact that the same deleterious genotypes are often transmitted through the egg at strictly mendelian frequencies (Khush, 1973). Gene expression in the pollen might thus at least appear to be a phenomenon of trivial consequence. Indeed, Heslop-Harrison (1979) rightly termed the gametophytic portion of the angiosperm life cycle, the "forgotten generation." This neglect, however, came about despite subtle but constant indications that pollen is the site of intense gene activity and selection. For example, Mok and Peloquin (1975) demonstrated that relatively heterozygous diploid pollen shows heterotic characteristics whereas relatively homozygous diploid pOllen does not. This was proof positive that genes are expressed (that is, transcribed and translated) in the pollen. 1 Department of Botany, University of Massachusetts Amherst, MA 01003, USA viii However, the implications for pollen biology of even this recent and well known study were not widely recognized.
