This book provides an important collection of new research that sheds light on many aspects of the evolutionary patterns of gymnosperms, angiosperms, and pteridophtes. The book includes a complete chloroplast genome sequence study and describes a method that induces the systemic silencing of target genes in the Ceratopteris gametophyte. It presents a study of how herbicide treatments reduce fern densities and create the establishment of regeneration. It also analyzes an EST dataset from G. biloba that reveals genes potentially unique to gymnosperms and includes a study of episodic rate acceleration in the ancestral grasses.
This third edition of the Handbook of Poisonous and Injurious Plants is designed to assist the clinician in the initial response to the needs of a child or adult exposed to a poisonous or injurious plant. It highlights common and important plants that lead to the adverse effects upon exposure, and it describes the mechanisms of action of the implicated toxin, clinical manifestations, and specific therapeutics, as available, for each. This truly comprehensive resource is botanically rigorous with insights from both the pharmacognosy and medical literature. At the same time, it is also for those who are interested in growing and enjoying the plants in their environment, filling in a not-often-...
Kaplan's Principles of Plant Morphology defines the field of plant morphology, providing resources, examples, and theoretical constructs that illuminate the foundations of plant morphology and clearly outline the importance of integrating a fundamental understanding of plant morphology into modern research in plant genetics, development, and physiology. As research on developmental genetics and plant evolution emerges, an understanding of plant morphology is essential to interpret developmental and morphological data. The principles of plant morphology are being brought into studies of crop development, biodiversity, and evolution during climate change, and increasingly such researchers are ...
The main aim of this book is to provide a developmental perspective to plant anatomy. Authors Steeves and Sawhney provide fundamental information on plant structure and development to students at the introductory level, and as a resource material to researchers working in nearly all areas of plant biology i.e., plant physiology, systematics, ecology, developmental genetics and molecular biology. The book is focused on angiosperm species with some examples from different groups of plants. "Essentials of Developmental Plant Anatomy" starts with an introductory chapter and a brief introduction to plant cell structure, which is followed by the structure of the flower, plant reproduction (vegetative and sexual) and the development and structure of embryo - the precursor to the plant body. Each chapter then deals with essential information on the shoot system, diversity of plant cells and tissues, the structure and development of the stem, leaf, root, and the secondary body.
How herbaria illuminate the past and future of plant science Collections of preserved plant specimens, known as herbaria, have existed for nearly five centuries. These pressed and labeled plants have been essential resources for scientists, allowing them to describe and differentiate species and to document and research plant changes and biodiversity over time—including changes related to climate. Maura C. Flannery tells the history of herbaria, from the earliest collections belonging to such advocates of the technique as sixteenth-century botanist Luca Ghini, to the collections of poets, politicians, and painters, and to the digitization of these precious specimens today. She charts the g...
The volume presents current ideas about the systematics and evolution of the Ranunculiflorae and most of its constituent families. A strong effort has been made to integrate DNA and morphological, anatomical, etc. evidence, and new ideas about the origin and phylogeny of the entire group as well as the Berberidaceae, Lardizabalaceae, Ranunculaceae, and Papaveraceae are arrived at.
This study analyzes the establishment of an iron foundry in the interior 18th-century of Angola. It was a fruit of the Portuguese Enlightenment, which encouraged investment in manufacturing, particularly of iron, a metal indispensable for military and technological purposes. However, the plans faced the resistance of African blacksmiths and founders who refused to learn foreign techniques and work processes. By emphasizing Central African agency, the book highlights the successful strategies of historical actors who scholars have largely ignored. Based upon a wide variety of sources from Brazilian, Portuguese, and Angolan archives, the book reconstructs how Africans were taken to work at the...
The Evolution of Plant Form is an exceptional new volume in Wiley-Blackwell’s highly successful and well established Annual Plant Reviews. Written by recognised and respected researchers, this book delivers a comprehensive guide to the diverse range of scientific perspectives in land plant evolution, from morphological evolution to the studies of the mechanisms of evolutionary change and the tools with which they can be studied. This title distinguishes itself from others in plant evolution through its synthesis of these ideas, which then provides a framework for future studies and exciting new developments in this field. The first chapter explores the origins of the major morphological in...
