Available in PDF, EPUB and Kindle. Book excerpt: The anther tapetum, present in all land plants, is a highly specialized, transient tissue surrounding the (micro-)spores and/or pollen grains during their development. Any tapetum malfunction causes male sterility. The exact knowledge of tapetum form and function therefore is indispensable not only for basic research, but also and especially in plant breeding and plant genetics. In fourteen contributions by reknown experts, a comprehensive account of the various characters and functions of the tapetum is provided, covering the areas of cytology, cytophysiology, biochemistry, tapetum development and function.
Book Synopsis Abiotic and Biotic Stress in Plants by : Arun Shanker
Download or read book Abiotic and Biotic Stress in Plants written by Arun Shanker and published by BoD – Books on Demand. This book was released on 2016-02-17 with total page 770 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of global climate change on crop production has emerged as a major research priority during the past decade. Understanding abiotic stress factors such as temperature and drought tolerance and biotic stress tolerance traits such as insect pest and pathogen resistance in combination with high yield in plants is of paramount importance to counter climate change related adverse effects on the productivity of crops. In this multi-authored book, we present synthesis of information for developing strategies to combat plant stress. Our effort here is to present a judicious mixture of basic as well as applied research outlooks so as to interest workers in all areas of plant science. We trust that the information covered in this book would bridge the much-researched area of stress in plants with the much-needed information for evolving climate-ready crop cultivars to ensure food security in the future.
Book Synopsis Male Sterility in Higher Plants by : Mohan L.H. Kaul
Download or read book Male Sterility in Higher Plants written by Mohan L.H. Kaul and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1016 pages. Available in PDF, EPUB and Kindle. Book excerpt: " . . . . . . Nature has something more in view than that its own proper males should fecundate each blossom. " Andrew Knight Philosophical Transactions, 1799 Sterility implicating the male sex solely presents a paradoxical situation in which universality and uniqueness are harmoniously blended. It maintains a built-in outbreeding system but is not an isolating mechanism, as male steriles, the "self-emasculated" plants, outcross with their male fertile sibs normally. Both genes (nuclear and cytoplasmic) and environment, individually as well as conjointly, induce male sterility, the former being genetic and the latter nongenetic. Genetic male sterility is controlled either exclusively by nuclear genes (ms) or by the complementary action of nuclear (lr) and cytoplasmic (c) genes. The former is termed genic and the latter gene-cytoplasmic male sterility. Whereas genic male sterility exhibits Mendelian inheritance, gene-cytoplasmic male sterility is non-Mendelian, with specific transmissibility of the maternal cytoplasm type. Genetic male sterility is documented in 617 species and species crosses com prising 320 species, 162 genera and 43 families. Of these, genic male sterility occurs in 216 species and 17 species crosses and gene-cytoplasmic male sterility in 16 species and 271 species crosses. The Predominance of species exhibiting genic male sterility and of species crosses exhibiting gene-cytoplasmic male sterility is due to the fact that for the male sterility expression in the former, mutation of nuclear genes is required, but in the latter, mutations of both nuclear and cytoplasmic genes are necessary.

Book Synopsis Flowering Plant Embryology by : Nels R. Lersten
Download or read book Flowering Plant Embryology written by Nels R. Lersten and published by John Wiley & Sons. This book was released on 2008-02-28 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Solanaceae, Biology and Systematics by : William G. D'Arcy
Download or read book Solanaceae, Biology and Systematics written by William G. D'Arcy and published by Columbia University Press. This book was released on 1986 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the puzzling phenomenon of new veiling practices among lower middle class women in Cairo, Egypt. Although these women are part of a modernizing middle class, they also voluntarily adopt a traditional symbol of female subordination. How can this paradox be explained? An explanation emerges which reconceptualizes what appears to be reactionary behavior as a new style of political struggle--as accommodating protest. These women, most of them clerical workers in the large government bureaucracy, are ambivalent about working outside the home, considering it a change which brings new burdens as well as some important benefits. At the same time they realize that leaving home and family is creating an intolerable situation of the erosion of their social status and the loss of their traditional identity. The new veiling expresses women's protest against this. MacLeod argues that the symbolism of the new veiling emerges from this tense subcultural dilemma, involving elements of both resistance and acquiescence.
