Book Description
As with nearly all living creatures, humans have always been attracted and intrigued by floral scents. Yet, while we have been manufacturing perfumes for at least 5000 years to serve a myriad of religious, sexual, and medicinal purposes, until very recently, the limitation of our olfactory faculty has greatly hindered our capacity to clearly and ob

Book Description
The flowering plants now dominate the terrestrial ecosystems of theplanet, and there are good reasons for supposing that the floweritself has been a major contributing factor to the spread of theAngiosperms. The flowers of higher plants not only contain theorgans of plant reproduction but are of fundamental importance ingiving rise to fruits and seeds which constitute a major componentof the human diet. This volume opens with a chapter describing a model for theevolution of the Angiosperm flower. Chapters 2 to 5 describe thecore development of the flower and include floral induction, floralpattering and organ initiation, floral shape and size, andinflorescence architecture. Chapters 6 to 8 focus on morespecialised aspects of floral development: monoecy, cytoplasmicmale sterility and flowering in perennials. Chapters 9 and 10address more functional aspects: flower colour and scent. The bookconcludes, appropriately, with a chapter on flowersenescence. Applied aspects are stressed wherever appropriate, and the book isdirected at researchers and professionals in plant genetics,developmental and molecular biology. The volume has been designed to complement an earlier volume in ourAnnual Plant Reviews series, O'Neill, S. D. and Roberts, J. A.(2002) Plant Reproduction.

Book Description
Studies in floral biology are largely concerned with how flowers function to promote pollination and mating. The role of pollination in governing mating patterns in plant populations inextricably links the evolution of pollination and mating systems. Despite the close functional link between pollination and mating, research conducted for most of this century on these two fundamental aspects of plant reproduction has taken quite separate courses. This has resulted in suprisingly little cross-fertilization between the fields of pollination biology on the one hand and plant mating-system studies on the other. The separation of the two areas has largely resulted from the different backgrounds and approaches adopted by workers in these fields. Most pollination studies have been ecological in nature with a strong emphasis on field research and until recently few workers considered how the mechanics of pollen dispersal might influence mating patterns and individual plant fitness. In contrast, work on plant mating patterns has often been conducted in an ecological vacuum largely devoid of information on the environmental and demographic context in which mating occurs. Mating-system research has been dominated by population genetic and theoretical perspectives with surprisingly little consideration given to the proximate ecological factors responsible for causing a particular pattern of mating to occur.

Book Description
The Damask rose (Rosa damascena Mill.) is the most important species used to produce rose water, attar of rose, and essential oils in the perfume and medicinal industry. However, despite the importance of Damask rose scent, the molecular and biochemical investigations of flower fragrance of this species are still in its primary stage. This book provides molecular, chemical diversities and physiological characterizations of floral scent production in R. damascena that were investigated by different experiments.

Book Description
Mimicry is a classic example of adaptation through natural selection. The traditional focus of mimicry research has been on defence in animals, but there is now also a highly-developed and rapidly-growing body of research on floral mimicry in plants. This has coincided with a revolution in genomic tools, making it possible to explore which genetic and developmental processes underlie the sometimes astonishing changes that give rise to floral mimicry. Being literally rooted to one spot, plants have to cajole animals into acting as couriers for their pollen. Floral mimicry encompasses a set of evolutionary strategies whereby plants imitate the food sources, oviposition sites, or mating partners of animals in order to exploit them as pollinators. This first definitive book on floral mimicry discusses the functions of visual, olfactory, and tactile signals, integrating them into a broader theory of organismal mimicry that will help guide future research in the field. It addresses the fundamental question of whether the evolutionary and ecological principles that were developed for protective mimicry in animals can also be applied to floral mimicry in plants. The book also deals with the functions of floral rewardlessness, a condition which often serves as a precursor to the evolution of mimicry in plant lineages. The authors pay particular attention to the increasing body of research on chemical cues: their molecular basis, their role in cognitive misclassification of flowers by pollinators, and their implications for plant speciation. Comprehensive in scope and conceptual in focus, Floral Mimicry is primarily aimed at senior undergraduates, graduate students, and researchers in plant science and evolutionary biology.

Book Description
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.

Book Description
The recent discovery of a large number of excellently preserved fossil flowers, studied with new techniques, and the comparative study of the flowers of extant basal clades of the angiosperms revolutionized the conception of early flower evolution. This volume brings together contributions of 17 palaeo- and neobotanists including critical reviews on the origin of flowers and the homologies of angiosperm floral organs, on the relationships of floral traits of magnoliids to those of lower eudicots (ranunculids, hamamelidids, dilleniids) and monocots, and articles on particular new Cretaceous fossils and new results on extant groups. These studies also influence the notion of early angiosperm evolution and of the macrosystematics of flowering plants.
