Available in PDF, EPUB and Kindle. Book excerpt: A -Study of pre-fertilization ovule ontogeny in Pisum sativum was made using improved microtechnical methods. Reexamination of megasporogenesis and megagametogenesis confirms earlier observations; the megasporocyte divides meiotically to produce a chalazal functional megaspore and three degenerative megaspores. Non-functional megaspore degradation is staggered; two chalazal megaspores are the first to degenerate while the third degenerative megaspore persists during initial expansion of the functional megaspore. An eight-nucleate, seven-celled embryo sac is produced by the functional megaspore after three sets of mitotic divisions. Ephemeral antipodals in the chalazal end of the embryo sac degenerate well before fertilization. The presence of wall ingrowths in the synergids is documented for Pisum.Nucellar degradation is closely correlated with megagametcphyte expansion and follows a sequential pattern of cytological changes involving cell wall thickening, starch mobilization, wall degradation, alteration of cytoplasm, and obliteration of nucellar cell structural integrity. The possibility of gametophytic regulation of nucellar cell breakdov7n is discussed. P is urn ovules are bitegmic. Both integuments are initiated in epidermal cells, but subsequent differentiation is radically different. A single vascular strand enters the ovule and terminates in the outer integument. Procambium is already organized when a megasporocyte is present. Vascular differentiation is correlated with the onset of megagametogenesis, but maturation of xylem and phloem by the time an embryo sac has organized is minimal. The relationships of integument and vascular ontogeny to embryo sac nutrition are discussed. A scheme of megagametophyte nutrition is proposed whereby the megagametophyte obtains all necessary nutrients from degenerate nucellus, in contrast to classical schemes of direct involvement by the parent sporophyte in embryo sac nutrition.

This book was released on 2012-12-06 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: view than its own proper males should fecundate each blossom." ANDREW KNIGHT Philosophical Transactions, 1799 Pollination mechanisms and reproduction have a decisive bearing upon rational procedures in plant breeding and crop production. This book intends to furnish' under one cover an integrated botanical, genetical and breeding-methodologi cal treatment of the reproductive biology of spermatophytes mainly angiosperms; it is based on an advanced topical course in plant breeding taught at the Hebrew University of Jerusa lem. We have tried to present a coverage which is concise, but as comprehensive as possible, of the pollination mechanism and modes of reproduction of higher plants, and to illustrate topics, whenever practicable, by examples from cultivated plants. Nevertheless, some relevant publications may have escaped our attention or may not be mentioned because of various limitations. The book is organized into three parts. The first part starts with an evaluation of the significance of the different pollination mechanisms for plant breeding and crop produc tion, describes modes of reproduction in higher plants and discusses ecology and dynamics of pollination. The second part is devoted to crops propagated by self pollination and describes specific breeding procedures for such crops. The third part details sexual reproduction in higher plants and handles three mechanisms involved in the prevention of self pollination and their utilization in plant breeding: sex expres sion, incompatibility, and male sterility.

This book was released on 2007-03-12 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: The formation, dispersal and germination of seeds are crucial stages in the life cycles of gymnosperm and angiosperm plants. The unique properties of seeds, particularly their tolerance to desiccation, their mobility, and their ability to schedule their germination to coincide with times when environmental conditions are favorable to their survival as seedlings, have no doubt contributed significantly to the success of seed-bearing plants. Humans are also dependent upon seeds, which constitute the majority of the world’s staple foods (e.g., cereals and legumes). Seeds are an excellent system for studying fundamental developmental processes in plant biology, as they develop from a single fertilized zygote into an embryo and endosperm, in association with the surrounding maternal tissues. As genetic and molecular approaches have become increasingly powerful tools for biological research, seeds have become an attractive system in which to study a wide array of metabolic processes and regulatory systems. Seed Development, Dormancy and Germination provides a comprehensive overview of seed biology from the point of view of the developmental and regulatory processes that are involved in the transition from a developing seed through dormancy and into germination and seedling growth. It examines the complexity of the environmental, physiological, molecular and genetic interactions that occur through the life cycle of seeds, along with the concepts and approaches used to analyze seed dormancy and germination behavior. It also identifies the current challenges and remaining questions for future research. The book is directed at plant developmental biologists, geneticists, plant breeders, seed biologists and graduate students.

Download or read book Genetic control of self-incompatibility and reproductive development in flowering plants written by Elizabeth G. Williams and published by Springer Science & Business Media. This book was released on 1994-08-31 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant reproductive biology has undergone a revolution during the past five years, with the cloning, sequencing and localization of the genes important in reproduction. These advantages in plant molecular biology have led to exciting applications in plant biotechnology, including the genetic engineering of male sterility and other reproductive processes. This book presents an interesting and contemporary account of these new developments from the scientists in whose laboratories they have been made. The chapters focus on two areas: the molecular biology of self-incompatibility, which is the system of self-recognition controlled by the S-gene and related genes; and the cellular and molecular biology of pollen development and genetic dissection of male sterility. Some chapters feature Arabidopsis, with its unique genetic system. Reproduction is vital for seed production in crop plants, and this book presents new approaches to manipulate plant breeding systems for the 21st century.

Available in PDF, EPUB and Kindle. Book excerpt: Cotton production today is not to be undertaken frivolously if one expects to profit by its production. If cotton production is to be sustainable and produced profitably, it is essential to be knowledgeable about the growth and development of the cotton plant and in the adaptation of cultivars to the region as well as the technology available. In addition, those individuals involved in growing cotton should be familiar with the use of management aids to know the most profitable time to irrigate, apply plant growth regulators, herbicides, foliar fertilizers, insecticides, defoliants, etc. The chapters in this book were assembled to provide those dealing with the production of cotton with the basic knowledge of the physiology of the plant required to manage the cotton crop in a profitable manner.
