Early Flowers and Angiosperm Evolution by Else Marie Friis,Peter R. Crane,Kaj Raunsgaard Pedersen Pdf

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 Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of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.

The Dawn Angiosperms by Xin Wang Pdf

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.

Phylogeny and Evolution of the Angiosperms by Douglas Soltis,Pamela Soltis,Peter Endress,Mark Chase,Steven Manchester,Walter Judd,Lucas Majure,Evgeny Mavrodiev Pdf

Although they are relative latecomers on the evolutionary scene, having emerged only 135?170 million years ago, angiosperms—or flowering plants—are the most diverse and species-rich group of seed-producing land plants, comprising more than 15,000 genera and over 350,000 species. Not only are they a model group for studying the patterns and processes of evolutionary diversification, they also play major roles in our economy, diet, and courtship rituals, producing our fruits, legumes, and grains, not to mention the flowers in our Valentine’s bouquets. They are also crucial ecologically, dominating most terrestrial and some aquatic landscapes. This fully revised edition of Phylogeny and Evolution of the Angiosperms provides an up-to-date, comprehensive overview of the evolution of and relationships among these vital plants. Incorporating molecular phylogenetics with morphological, chemical, developmental, and paleobotanical data, as well as presenting a more detailed account of early angiosperm fossils and important fossil information for each evolutionary branch of the angiosperms, the new edition integrates fossil evidence into a robust phylogenetic framework. Featuring a wealth of new color images, this highly synthetic work further reevaluates long-held evolutionary hypotheses related to flowering plants and will be an essential reference for botanists, plant systematists, and evolutionary biologists alike.

Comparative Embryology of Angiosperms Vol. 1/2 by Brij M. Johri,Kunda B. Ambegaokar,Prem S. Srivastava Pdf

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.

Botany- Taxonomy Of Angiosperms by Dr. Manoj Kumar Sharma,Dr. Anil Kumar,Dr. Rajesh S. Deshmukh,Dr. Vinayaka K.S Pdf

Plant taxonomists seek to learn as much as they can about the earth's plant knowledge and gather them into systematic plants. Due to the vastness of Earth's vegetation, knowledge cannot be gathered without first being organised. To begin, we must take an exhaustive tally of all plant life in a given region and, eventually, the whole planet. The initial step in taxonomy is the gathering and preparation of herbarium specimens for future research. Identification is the next step, and it requires identification descriptions, drawing pictures, and creating keys. Taxonomy's main aim is to accurately identify all plant plants, and its secondary goal is to order them according to a universally agreed categorization system. The process of identification entails deciding whether or not a taxon (plural taxa) is the same as or closely related to a previously known taxon. A plant may only be properly identified if it is placed in the correct taxonomic family, and only then can it be properly classified as a species. This may be done with the aid of Floras, monographs, and herbaria, all of which are now in circulation. A plant is considered to be a new species when all attempts to identify it as a member of an existing species have been fruitless. Assembling plants into taxonomic groups based on their shared characteristics is known as classification. The result is a well-thought-out classification system in which any number of species may be placed in any given category. Strongly linked groups are grouped together in accordance with the principles underlying any current system of classification, which are based on their genetic link.

Embryogenesis in Angiosperms by Valayamghat Raghavan Pdf

For the first time in synoptic form, this book presents a clear account of the most recent knowledge of embryogenesis in flowering plants. A multidisciplinary approach is adopted bringing together the foundations of tissue culture, biochemistry, and cell and molecular biology which have supported the rapid progress of research in angiosperm development. In the first part of the book, the author draws a broad picture of the processes involved in embryogenesis. A brief introduction to procedures is followed by chapters on developmental, cellular, biochemical and experimental aspects of embryogenesis, and on somatic and pollen embryogenesis. Later sections on the regulation of gene expression and mechanisms of programming developmental information precede a treatment of some practical applications resulting from the study of embryos. Two techniques discussed which are aimed towards the goal of enhancing crop productivity in a dynamic and expanding field are embryo rescue from inviable crosses and preservation of germ plasm.
