The Embryology of Angiosperms, 6th Edition by S.S Bhojwani, S.P. Bhatnagar & P.K. Dantu Pdf

For the last 40 years this book has served well the students of Botany, Agriculture and Forestry for their regular courses like BSc. (General and Hons) and MSc., as well as competitive examinations. It has stood the test of time due to the authors’ zeal to update it regularly with inputs from latest developments in the field. Since the last revision of the book, the methods used to study plant embryology have changed radically. Powerful modern biological techniques are now being applied to understand the developmental aspects and genetic and molecular bases of embryological processes. It has become possible to generate tissue specific mutants by T-DNA insertional mutagenesis, use of green fluorescent protein probes for live imaging of growing cells and tissues and to analyze gene expression in few-celled structures, such as early stages of embryo, and constituent cells of the male and female gametophytes. These techniques, combined with the development of high resolution confocal laser scanning microscopy, have provided non-invasive methods to view live processes, such as pollen tube growth in the pistil and double fertilization under in situ conditions. The book has been translated into Japanese and Korean languages. KEY FEATURES • Well established text with content rigorous enough for both UG and PG studies • Covers important topics like development and structure of male and female gametophytes, pollination, fertilization, sexual incompatibility, development of endosperm and embryo, polyembryony, apomixis and seed development • Describes embryology in relation to taxonomy and experimental and applied embryology Use of tables and figures to depict important data and information • Updated as per the new developments in the study of plant embryology

Embryology of Angiosperms by B. M. Johri Pdf

Thirty-four years have elapsed since the publication of the late Professor P. Maheshwari's text, An Introduction to the Embryology of Angiosperms, a work which for many years served as an invaluable guide for students and a rich source book for research workerso Various texts dealing with sections of the braad spectrum oftopics encompassed by Maheshwari in his book have appeared in the interim, but a compendious modem work dealing with the whole field has been lacking. This present volume splendidly meets the need, and it is altogether fitting that Professor B. M. lohri, long an associate and close colleague of Professor Maheshwari and himself a prolific contributor to the subject, should have undertaken the task of editing it. When Maheshwari wrote, it was stiIl feasible for one author to handIe the subject, but today even someone with his fine bread th of vision and depth of understanding could not, alone, do it justice. So the effort has to be a collaborative one; and Professor lohri's achievement has been to bring together a team of authoritative collaborators, assign them their responsibilities, and put them to work to produce a text as integrated in its treatment as the diversity of the subject would allow. The product vividly illustrates the advances that have been made in the study of angiosperm reproductive systems in the last 30 years, and the book is surely destined to become the new standard for student and researcher 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.

An Introduction to the Embryology of Angiosperms by Panchanan Maheshwari Pdf

First 3 paragraphs of Preface: In these days of intense activity, when hundreds of papers are being published in every field of botany in a steadily increasing number of periodicals and in a multitude of languages, no apology is needed for an attempt to summarize the existing state of our knowledge in any branch of the subject and to point out the future possibilities in it. Since the publication of Coulter and Chamberlain's "Morphology of Angiosperms" in 1903, no comprehensive account of this aspect of botany has appeared in the English language. The original impetus for writing this work resulted from a course of lectures which I gave on the subject in 1930 when I was teaching at the Agra College. Several colleagues and pupils then suggested that I should produce a book on the embryology of angiosperms. This suggestion was repeated by Professor G. Tischler of the University of Kiel, whom I visited in 1936. Teaching and administrative dutes and other difficulties made it impossible for me to carry on this work in India at the speed I should have liked. Soon after the war was over in 1945, therefore, I took the manuscript to the United States in order to revise it and put it in shape for publication. In a strict sense, embryology is confined to a study of the embryo, but most botanists also include under it the events which lead on to fertilization. I am in agreement with this wider comprehension of the subject and have therfore included in this volume not only an account of the embryo and endosperm, but also an account of the development of the male and female gametophytes and fertilization. To emphasize the recent trends of research in the subject, two chapters of a general nature have been added, one dealing with embryology in relation to taxonomy, and the other with experimental embryology. In the former, an attemt has been made to indicate the possibilities of the embryological method in the solution of problems of systematic botany. In the latter, emphasis has been placed on the contacts between embryology, cytology, genetics, and plant physiology.

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.

Flowering Plant Embryology by Nels R. Lersten Pdf

Drawing from a lifetime of teaching botany, Dr. Nels Lersten presents the study of the structures and processes involved in the reproduction of plants in his text Flowering Plant Embryology. This richly illustrated reference text, with more than 350 figures and illustrations, presents general angiosperm embryology as it applies to economically important plants. The unique focus on economically important species increases the relevance of this book to today’s students and researchers in the plant sciences. Lersten emphasizes the plant species that affect human livelihood, including weeds and other cultivated plants that are used for commercial products. Selected from the thousands of economically important plants, the examples chosen for illustration and discussion are familiar, especially to students from North America, Northern Europe, and Japan. Although the emphasis of this book is economically important plants, the information within applies to almost all flowering plants. Extremely readable and well-written, this book is neither dense nor academic in tone. Lersten treats topics with a uniformity of style and organization that enhances comprehension. Terms are well-defined and the derivation of each is explained to further facilitate student learning. The book presents research results, hypotheses, and speculations about why things are as they are, with supporting facts and specific examples that provide a firm foundation for students’ understanding of embryological diversity among economic plants.

Embryology of Flowering Plants: Terminology and Concepts, Vol. 3 by T B Batygina Pdf

Plant embryology, dealing with the regularities of initiation and the first stages of development of an organism, is now flourishing because of the overall progress being made in natural sciences. Such discoveries of the 20th century as production of plants from a single somatic cell, experimental haploidy, and parasexual hybridization were of general biological significance. The combined efforts of embryologists, geneticists and molecular biologists yielded the discovery of specific genes that control meiosis, egg cell development and early stages of embryogenesis. The tendency to synthesize data of embryology and genetics has become increasingly noticeable. It is connected with the fact that the majority of problems connected with morphogenesis, such as differentiation, specialization, the evaluation of features and the definition of the notionsgene and feature andgenotype and phenotype concern embryology and genetics (embryogenetics) in one way or another. Evolutionary embryology has given rise to a new approach to the study of problems of adaptation in plants. In connection with the problem of preserving biological diversity under conditions of ecological stress, special attention is paid to ecological embryology, revealing the critical periods in early ontogenesis and plasticity and tolerance of reproductive systems at the level of species and population. The study of variability of morphogenesis and phenotype in population (life cycle variations and the diversity of reproductive systems) is the most important point in the population embryology of plants.
