Book excerpt: Angiosperms are the most diversi ed plant group in the world, being represented by ca 300,000 species in about 400 families. Like all of Life, including ourselves, they have had their own history and gone through many evolutionary stages before they arrived at their current forms. The origin of Angiospermae ( owering plants) has been the subject of much dispute because this is a key event in the history of life, and has a far-reaching in uence on our understanding of relationships among seed plants as a whole as well as within the angiosperms. Until recently most of palae- otanists recognized angiosperms only from the Cretaceous and younger strata. This contradicts the results of molecular analyses. I have been working on Mesozoic fossil plants for the past two decades, during which time I have studied a number of fossil plants. Some of these fossil plants have been published as Jurassic angiosperms, and, unsurprisingly, many questions and doubts have been raised about them. These questions need to be addressed se- ously and journal papers do not provide suf cient space to compare and relate these early angiosperms. In this book these pioneer angiosperms are documented in detail, sometimes with new specimens not studied before. Also, I propose a de nition of angiosperms that could be adopted in palaeobotany. My aim is to improve clarity and objectivity of judgment about what constitutes a fossil angiosperm.

Available in PDF, EPUB and Kindle. Book excerpt: Mr Hughes argues that approaches (previous to 1976) to the evolutionary origin and early history of or flowering plants have been inadequate and misleading. He suggests that the date is in the Cretaceous period and there is a good chance of ancestors being found if other fossil plants of that period are studied.

Download or read book The Origins of Angiosperms and their Biological Consequences written by Else Marie Friis and published by Cambridge University Press. This book was released on 1989-05-18 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was originally published in 1989. The dramatic radiation of the angiosperms towards the end of the Early Cretaceous initiated major changes in terrestrial ecosystems throughout the world. Dramatic changes in the flora and fauna were exemplified by the development of angiosperm-dominated plant communities and the rapid diversification of mammals, birds and insects. Written specifically for use by advanced undergraduate and graduate students, the book presents an overview of works on the origins of angiosperms and the ecological effects upon terrestrial life of their rapid radiation. It will be of particular value to students of palaeobiology and ecology, as well as to those studying evolutionary biology and systematics.

Download or read book Comparative and Evolutionary Genomics of Angiosperm Trees written by Andrew Groover and published by Springer. This book was released on 2017-11-21 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marking the change in focus of tree genomics from single species to comparative approaches, this book covers biological, genomic, and evolutionary aspects of angiosperm trees that provide information and perspectives to support researchers broadening the focus of their research. The diversity of angiosperm trees in morphology, anatomy, physiology and biochemistry has been described and cataloged by various scientific disciplines, but the molecular, genetic, and evolutionary mechanisms underlying this diversity have only recently been explored. Excitingly, advances in genomic and sequencing technologies are ushering a new era of research broadly termed comparative genomics, which simultaneously exploits and describes the evolutionary origins and genetic regulation of traits of interest. Within tree genomics, this research is already underway, as the number of complete genome sequences available for angiosperm trees is increasing at an impressive pace and the number of species for which RNAseq data are available is rapidly expanding. Because they are extensively covered by other literature and are rapidly changing, technical and computational approaches—such as the latest sequencing technologies—are not a main focus of this book. Instead, this comprehensive volume provides a valuable, broader view of tree genomics whose relevance will outlive the particulars of current-day technical approaches. The first section of the book discusses background on the evolution and diversification of angiosperm trees, as well as offers description of the salient features and diversity of the unique physiology and wood anatomy of angiosperm trees. The second section explores the two most advanced model angiosperm tree species (poplars and eucalypts) as well as species that are soon to emerge as new models. The third section describes the structural features and evolutionary histories of angiosperm tree genomes, followed by a fourth section focusing on the genomics of traits of biological, ecological, and economic interest. In summary, this book is a timely and well-referenced foundational resource for the forest tree community looking to embrace comparative approaches for the study of angiosperm trees.
Download or read book Early Flowers and Angiosperm Evolution written by Else Marie Friis and published by Cambridge University Press. This book was released on 2011-08-18 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent discovery of diverse fossil flowers and floral organs in Cretaceous strata has revealed astonishing details about the structural and systematic diversity of early angiosperms. Exploring the rich fossil record that has accumulated over the last three decades, this is a unique study of the evolutionary history of flowering plants from their earliest phases in obscurity to their dominance in modern vegetation. The discussion provides comprehensive biological and geological background information, before moving on to summarise the fossil record in detail. Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of the pattern of angiosperm evolution through time. Synthesising palaeobotanical data with information from living plants, this unique book explores the latest research in the field, highlighting connections with phylogenetic systematics, structure and the biology of extant angiosperms.

Available in PDF, EPUB and Kindle. Book excerpt: COMPARATIVE EMBRYOLOGY OF ANGIOSPERMS is a review of the developmental processes leading to sexual reproduction in flowering plants. On the basis of embryological data and certain evidences from other areas of study, it lays special emphasis on the relationship among and within the families and orders of angiosperms. Occasionally, inaccuracies in observation and interpretation are pointed out, alternative interpretations offered, gaps in our knowledge highlighted, and prospects outlined. The text is documented with 36 tables, 376 figures, and about 5000 literature citations, which contribute to making this book comprehensive. Besides students and research workers interested in angiosperm embyology, taxonomists, plant breeders, agriculturists, and horticulturists will also find much useful information in this treatise.
