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.

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.

"Double Fertilization" provides a comprehensive overview of all aspects of this central event in the reproduction and development of flowering plants. Written by Val Raghavan, The Ohio State University, an acknowledged expert in plant developmental biology, the book vividly describes the molecular and cellular steps of the unique and complex fertilization process that culminates in the formation of embryo and endosperm, focusing on the latest results from the model plant Arabidopsis. The text is complemented by excellent illustrations, including 16 color plates. Since embryo and endosperm constitute the edible parts of many seeds and grains widely used in human and animal nutrition, an understanding of the fertilization process has great relevance for genetic engineering aimed at improving the nutritional quality of crop plants. This book is ideally suited to researchers and graduate students seeking a coherent view of current perspectives on embryogenesis and endosperm development in flowering plants.

Drawing on the combined efforts of embryologists, geneticists, and molecular biologists, this third volume studies the variability of morphogenesis and phenotype in population. It pays particular attention to ecological embryology, revealing the critical periods in early ontogenesis as well as plasticity and tolerance of reproductive systems at the level of species and population. Highlighting the preservation of species diversity under conditions of ecological stress, it examines problems connected with morphogenesis, such as differentiation, specialization, and evaluation of features and considers the definition of the notions of "gene and feature" and "genotype and phenotype".

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

With the advent of transgene technology, plant physiology, over the last ten years, has undergone a 'sea-change' and there is a need to 'rewrite'. Molecular Physiology and Biotechnology of Flowering Plants attempts to provide an uptodate account. The first chapter Seed Germination and Seedling: Beginning of an Establishment discusses light and hormonal control of these processes followed by chapters on vegetative and reproductive phases of plants. In Vegetative Phase novel concepts such as 'Stem-cell' and 'Determination of Cell-fate' and conceptual changes concerning apical dominance and stomatal physiology, followed by Reproductive Phase where floral evocation, floral stimulus and gene expression during flowering are discussed.

Apomixis is the consequence of a concerted mechanism that harnesses the sexual machinery and coordinates developmental steps in the ovule to produce an asexual (clonal) seed. Altered sexual developments involve widely characterized functional and anatomical changes in meiosis, gametogenesis, and embryo and endosperm formation. The ovules of apomictic plants skip meiosis and form unreduced female gametophytes whose egg cells develop into a parthenogenetic embryo, and the central cells may or may not fuse to a sperm to develop the seed endosperm. Thus, functional apomixis involves at least three components, apomeiosis, parthenogenesis, and endosperm development, modified from sexual reproduction that must be coordinated at the molecular level to progress through the developmental steps and form a clonal seed. Despite recent progress uncovering specific genes related to apomixis-like phenotypes and the formation of clonal seeds, the molecular basis and regulatory network of apomixis is still unknown. This is a central problem underlying the current limitations of apomixis breeding. This book collates twelve publications addressing different topics around the molecular basis of apomixis, illustrating recent discoveries and advances toward understanding the genetic regulation of the trait, discussing the possible origins of apomixis and the remaining challenges for its commercial deployment in plants.
