Understanding Flowers and Flowering Second Edition by Beverley Glover Pdf
Flowers are the beautiful and complex reproductive structures of the angiosperms, one of the most diverse and successful groups of living organisms. The underlying thesis of this book is that to fully understand plant development (and why flowers differ in shape, structure and colour), it is necessary to understand why it is advantageous for them to look like they do. Conversely, in order to fully understand plant ecology, it is necessary to appreciate how floral structures have developed and evolved. Uniquely, this book addresses flowers and flowering from both a molecular genetic perspective (considering flower induction, development and self-incompatibility) and an ecological perspective (looking at the selective pressures placed on plants by pollinators, and the consequences for animal-plant co-evolution). Understanding Flowers and Flowering, the first edition of which won BES Marsh Book of the Year in 2009, begins by considering the evolution of flowers and the history of research into their development. This is followed by a detailed description of the processes which lead to flower production in model plants. The book then examines how flowers differ in shape, structure and colour, and how these differences are generated. Finally it assesses the role of these various aspects of floral biology in attracting pollinators and ensuring successful reproduction. This new edition has been completely revised and updated to reflect the latest advances in the field, especially an increased understanding of the evolution of floral traits. New chapters consider the genetic basis of the floral transition in diverse species, as well as the evolutionary lability of floral form. There is a new focus throughout on both phylogenetic position and morphological diversity across the angiosperm phylogeny. Understanding Flowers and Flowering continues to provide the first truly integrated study of the topic - one that discusses both the how and why of flowering plant reproductive biology.
Floral morphology remains the cornerstone for plant identification and studies of plant evolution. This guide gives a global overview of the floral diversity of the angiosperms through the use of detailed floral diagrams. These schematic diagrams replace long descriptions or complicated drawings as a tool for understanding floral structure and evolution. They show important features of flowers, such as the relative positions of the different organs, their fusion, symmetry, and structural details. The relevance of the diagrams is discussed, and pertinent evolutionary trends are illustrated. The range of plant species represented reflects the most recent classification of flowering plants based mainly on molecular data, which is expected to remain stable in the future. This book is invaluable for researchers and students working on plant structure, development and systematics, as well as being an important resource for plant ecologists, evolutionary botanists and horticulturists.

Floral Biology by Professor & Canada Research Chair Department of Botany Spencer C H Barrett Pdf
This volume highlights the new synthesis of pollination biology and plant mating systems which is rejuvenating the two-hundred-year-old discipline of floral biology. It provides a current examination of the evolution and functional significance of floral traits in animal-pollinated plants, combining ecological and genetic studies with natural history approaches and theoretical modeling. Divided into three sections, the book begins with the first English translation of Christian Konrad. Sprengel's introduction to his classic work and a historical analysis of his observations. The second section addresses current conceptual problems in floral biology, concentrating on floral diversification, floral longevity, pollen dispersal and mating patterns, the ecology of geitonogamous pollination, and flower size dimorphism in plants with unisexual flowers. The final chapters of the book examine model systems and include the evolution of floral morphology and function, deceit pollination, reproductive success and gender variation, stylar polymorphisms, and the evolution of flowers in relation to insect pollinators on islands. With its a detailed treatment of the selective forces shaping floral diversification in animal-pollinated plants, Floral Biology provides ecologists, evolutionary biologists, and botanists with a wealth of current information. Everyone interested in the evolution of flowering plants will benefit from this timely, authoritative resource on the interactions between insects and plants.
The Molecular Biology and Biotechnology of Flowering by Brian R. Jordan Pdf
Containing contributions from experts from the USA, Europe and New Zealand, this book provides an overview of the molecular mechanisms associated with flowering. The first edition was published in 1993 as The Molecular Biology of Flowering. The second edition has been thoroughly revised and updated to cover the major advances that have been made in the area in the last thirteen years.

Introduction to Floriculture provides an introduction to commercial floriculture, containing information on major and minor greenhouse and field crops, and includes potted plants and cut flowers. The book is organized into two parts. Part I on cut flowers discusses the history and propagation of chrysanthemums, carnations, roses, snapdragons, orchids, gladiolus, and minor cut crops. Part II on potted plants includes bulbous plants, azaleas, pot mums, African violets, poinsettias, and Easter lilies. This book was written for students who have been exposed to a sufficient number of biology courses to acquaint them with many of the terms and plant processes discussed in the text. It would be beneficial if they have also taken a course in greenhouse management or are taking one concurrently with their floriculture course. The book can be used by commercial growers who constantly seek more information to enable them to realize maximum gain from the investments of labor, time, and capitol they have placed in this challenging field.
Petunia belongs to the family of the Solanaceae and as such is closely related to important crop species like tomato, potato, eggplant, pepper and tobacco. With around 35 species described it is one of the smaller genera and among those there are two groups of species that make up the majority of them: the purple flowered P.integrifolia group and the white flowered P.axillaris group. It is assumed that interspecific hybrids between members of these two groups have laid the foundation for the huge variation in cultivars as selected from the 1830’s onwards. Petunia thus has been a commercially important ornamental since the early days of horticulture. Despite that, Petunia was in use as a research model only parsimoniously until the late fifties of the last century. By then seed companies started to fund academic research, initially with the main aim to develop new color varieties. Besides a moment of glory around 1980 (being elected a promising model system, just prior to the Arabidopsis boom), Petunia has long been a system in the shadow. Up to the early eighties no more then five groups developed classical and biochemical genetics, almost exclusively on flower color genes. Then from the early eighties onward, interest has slowly been growing and nowadays some 20-25 academic groups around the world are using Petunia as their main model system for a variety of research purposes, while a number of smaller and larger companies are developing further new varieties. At present the system is gaining credibility for a number of reasons, a very important one being that it is now generally realized that only comparative biology will reveal the real roots of evolutionary development of processes like pollination syndromes, floral development, scent emission, seed survival strategies and the like. As a system to work with, Petunia combines advantages from several other model species: it is easy to grow, sets abundant seeds, while self- and cross pollination is easy; its lifecycle is four months from seed to seed; plants can be grown very densely, in 1 cm2 plugs and can be rescued easily upon flowering, which makes even huge selection plots easy to handle. Its flowers (and indeed leaves) are relatively large and thus obtaining biochemical samples is no problem. Moreover, transformation and regeneration from leaf disc or protoplast are long established and easy-to-perform procedures. On top of this easiness in culture, Petunia harbors an endogenous, very active transposable element system, which is being used to great advantage in both forward and reverse genetics screens. The virtues of Petunia as a model system have only partly been highlighted. In a first monograph, edited by K. Sink and published in 1984, the emphasis was mainly on taxonomy, morphology, classical and biochemical genetics, cytogenetics, physiology and a number of topical subjects. At that time, little molecular data was available. Taking into account that that first monograph will be offered electronically as a supplement in this upcoming edition, we would like to put the overall emphasis for the second edition on molecular developments and on comparative issues. To this end we propose the underneath set up, where chapters will be brief and topical. Each chapter will present the historical setting of its subject, the comparison with other systems (if available) and the unique progress as made in Petunia. We expect that the second edition of the Petunia monograph will draw a broad readership both in academia and industry and hope that it will contribute to a further expansion in research on this wonderful Solanaceae.
