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 Cork Oak Woodlands on the Edge by : James Aronson
Download or read book Cork Oak Woodlands on the Edge written by James Aronson and published by Island Press. This book was released on 2012-09-26 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cork oak has historically been an important species in the western Mediterranean—ecologically as a canopy or “framework” tree in natural woodlands, and culturally as an economically valuable resource that underpins local economies. Both the natural woodlands and the derived cultural systems are experiencing rapid change, and whether or not they are resilient enough to adapt to that change is an open question. Cork Oak Woodlands on the Edge provides a synthesis of the most up-to-date, scientific, and practical information on the management of cork oak woodlands and the cultural systems that depend on cork oak. In addition, Cork Oak Woodlands on the Edge offers ten site profiles written by local experts that present an in-depth vision of cork oak woodlands across a range of biophysical, historical, and cultural contexts, with sixteen pages of full-color photos that illustrate the tree, agro-silvopastoral systems, products, resident biodiversity, and more. Cork Oak Woodlands on the Edge is an important book for anyone interested in the future of cork oak woodlands, or in the management of cultural landscapes and their associated land-use systems. In a changing world full of risks and surprises, it represents an excellent example of a multidisciplinary and holistic approach to studying, managing, and restoring an ecosystem, and will serve as a guide for other studies of this kind.
