Description: This book presents a synthesis of the extensive information available on the biology of Bromeliacea, a largely neotropical family of about 2700 described species. The author emphasizes reproductive and vegetative structure, related physiology, ecology, and evolution, rather than floristics and taxonomy. Guiding questions include: Why is this family inordinately successful in arboreal (epiphytic) and other typically stressful habitats and why is this family so important to extensive fauna beyond pollinators and frugivores in the forest canopy? Extraordinary and sometimes novel mechanisms that mediate water balance, tolerance for high and low exposures, and mutualisms with ants have received much study and allow interesting comparisons among plant taxa and help explain why members of this taxon exhibit more adaptive and ecological variety than most other families of flowering plants. This volume concentrates on function and underlying mechanisms, thus it will round out a literature that otherwise mostly ignores basic biology in favor of taxonomy and horticulture.
Description: Plant cell and tissue culture is a relevant area of experimental biology that has been developed for some decades to become an indispensable tool of plant biotechnology. Progress in this area, sometimes tumultuous, has been regularly recorded by the proceedings of the congresses of the International Association for Plant Tissue Culture which have been held every four years in several continents. This book reports plenary lectures, keynote lectures and invited oral presentations given at the last congress held in Florence. It is a useful reference guide both for established scientists and students on both traditional and emerging fields of plant biology. The following topics are covered: In vitro Culture and Plant Regeneration; Plant Propagation; Haploids; Somatic Hybridisation; Reproductive Systems; Genetic Variability; Gene Transfer; Organelles; Biotechnology of Tropical and Subtropical Species; Agronomic Traits; Somatic Embryogenesis; Meristems; Cell Surface; Growth Regulators; Reception and Transduction of Signals; Gene Expression under Extreme Conditions; Primary Metabolism; Secondary Metabolism; Transport; Large Scale Production.
Description: The chapters in this Proceedings are divided into six areas of interest, reflecting the six sessions of the symposium: (1) Global patterns of carbon allocation and partitioning; (2) Managed and unmanaged ecosystems; (3) Sustainable agroecosystems; (4) Groundwater quality; (5) Genetics, physiology, and molecular biology; and (6) Contemporary methods for measuring root dynamics. The sponsoring society has made a particular effort in these symposia to include root scientists from the former Soviet Union and Warsaw Pact countries. Therefore, when combined with manuscripts from the U.S.A., western Europe, Australia, New Zealand, P.R. China and Asia, a good sampling of world root research is presented in the sixty-seven chapters. This volume should prove valuable as a reference and source of communication for root scientists.
Description: Written by the leading experts in the field, this book examines the evolutionary advantages of gender dimorphism the occurence of two sexual forms - and sexual dimorphism dimorphism in secondary sex characters - in flowering plants. Gender dimorphism is found in approximately 10% of flowering plant species and has been an active topic of research. By contrast, sexual dimorphism in plants is much less widely appreciated. The book consists of three sections: The first introduces readers to the tremendous variety of breeding systems and their evolution in plants and sets the stage for a consideration of the evolution of dimorphism in reproductive and non-reproductive characters. The second section deals with the evolution of secondary sexual characters, including the theory related to the evolution of sexual dimorphism and its empirical patterns. The last section deals with the genetics of gender expression and of secondary sexual characters.
