Book Description
The number of currently known, described and accepted plant species is ca 374,000, of which approximately 295,00 (79%) are angiosperms. Almost 90% of this huge number of flowering plants is pollinated by animals (mostly insects) via nectar-mediated interactions. Notably, three-fourths of the leading global crop plants produce nectar and are animal pollinated, which is estimated to account for one-third of human food resources. Nectar can also be produced on tissues outside of flowers, by so-called extrafloral nectaries, and commonly mediate interactions with ‘body-guard’ ants and other pugnacious insects that defend the plant from herbivores. Extrafloral nectar is present in almost 4,000 plant species, a majority of them in the angiosperms. This brief summary on the occurrence of nectar in the plant kingdom is just to highlight that nectar has a fundamental role in two basal functions that allow the maintenance of our ecosystems: sexual plant reproduction and protection of plants from herbivory. Despite playing essential ecological and evolutionary functions, our current knowledge about nectar is largely incomplete; however, new research directions and perspectives on nectaries and nectars have arisen in recent years. In the last two decades, there were only a few ‘moments’ in which nectar was the main character in international meetings or in published books. In 2002, the first (and only) international meeting “Nectar and nectary: from biology to biotechnology” dedicated exclusively to nectar and nectaries was held in Italy (Montalcino, Siena) and in 2003 the proceedings were published in a special volume of Plant Systematics and Evolution (238, issue 1-4). In 2007, the book Nectar and Nectaries was published (Springer) with most of the contributions provided by authors that attended the meeting in Italy. Another book dedicated to nectar was published in 2015 (Nectar: Production, Chemical Composition and Benefits to Animals and Plants, Nova Science Publishers) covering aspects mainly related to nectar chemical composition and plant-pollinator interactions. Similarly, symposia focused on nectar have been organized within the International Botanical Congress in 2011 and 2017. Considering that the last few years has yielded essential developments in the understanding of nectar biology, we thought now is the moment to further stimulate research on this important topic. This aim has been met through 18 papers published in our Research Topic New Perspectives on the Biology of Nectaries and Nectars, with subjects spanning evolution and ecology to nectar chemistry and nectary structure.

Book Description
Nectar is the most important reward offered by plants to pollinating animals. This book is a modern and interdisciplinary text on nectar and nectaries, prompted by the expansion of knowledge in ecological and molecular fields, and the strong recent interest in pollination biology. The topics covered vary widely: they include historical aspects, the structure and ultrastructure of nectaries and relationships to plant systematics, the dynamics of nectar secretion, nectar chemistry and the molecular biology of defence proteins, and more.

Book Description
These volumes are an exhaustive source of information on the control and regulation of flowering. They present data on the factors controlling flower induction and how they may be affected by climate and chemical treatments. For each plant, specific information is provided on all aspects of flower development, including sex expression, requirements for flowering initiation and development, photoperiod, light density, vernalization, and other temperature effects and interactions. Individual species are described from the standpoint of juvenility and maturation, morphology, induction and morphogenesis to anthesis. All information is presented alphabetically for easy reference

Book Description
Floral Biology attempts to show how floral biologists conduct their experiments and what techniques they employ in floral biology. The techniques employed include those of physics, chemistry, physiology, psychology, genetics, and ecology, and so constitute a broad training in biology that may be useful and acceptable in other fields. Organized into 11 chapters, this book begins with a discussion on sex in flowers; the biology of the floral parts; agencies of pollination; and the pollen, nectar, and nectaries. Some chapters follow on pollination by birds, bats, and insects. The features of entomophilous flowers and isolating mechanisms in flowers are also described. Some hints for students, such as the tools required, how to make them, and a schedule of procedure for examining the floral biology of a species, are given in the last chapter. This book will attract workers, who, armed with the techniques and stimulated by the findings of the investigators, can introduce the floral biology to other fields.

Book Description
Floral nectar is a sweet, aqueous secretion that mainly consists of sugars and to a lesser extent amino acids. It is offered by plants to entice pollinators and to ensure pollination and thus sexual reproduction. This book discusses several benefits of plant nectar. It also discusses the production and chemical composition of nectar.

Book Description
This book has a wider approach not strictly focused on crop production compared to other books that are strictly oriented towards bees, but has a generalist approach to pollination biology. It also highlights relationships between introduced and wild pollinators and consequences of such introductions on communities of wild pollinating insects. The chapters on biochemical basis of plant-pollination interaction, pollination energetics, climate change and pollinators and pollinators as bioindicators of ecosystem functioning provide a base for future insights into pollination biology. The role of honeybees and wild bees on crop pollination, value of bee pollination, planned honeybee pollination, non-bee pollinators, safety of pollinators, pollination in cages, pollination for hybrid seed production, the problem of diseases, genetically modified plants and bees, the role of bees in improving food security and livelihoods, capacity building and awareness for pollinators are also discussed.

Book Description
The recent application of molecular genetics to problems of developmental biology has provided us with greater insight into the molecular mechanisms by which cells determine their developmental fate. This is particularly evident in the recent progress in understanding of developmental processes in model animal systems such as Drosophila melanogaster and Caenorhabditis elegans. De spite the use of plants in some of the earliest genetics experiments, the elucida tion of the molecular bases of plant development has lagged behind that of animal development. However, the emergence of model systems such as Arabi dopsis thaliana, amenable to developmental genetics, has led to the beginning of the unraveling of the mysteries behind plant morphogenesis. This atlas of the morphology and development of the weed Arabidopsis is in tended to be a reference book, both for scientists already familiar with plant anatomy and for those utilizing Arabidopsis who have come from other fields. The primary concentration is on descriptions rather than interpretations, as interpretations evolve and change relatively rapidly, whereas the evolution of plant form takes place on a much longer time scale. Molecular genetics and the use of mutants to probe wild-type gene function rely on the wild-type being well characterized. With this in mind, an attempt was made to present detailed descriptions of wild-type structure and development, to provide a foundation for comparison with the selected mutants in the atlas. More importantly, it is hoped that the atlas will serve as a valuable resource in the characterization of new mutants.
