This book was released on 1977 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'approche des problèmes de division et de différenciation cellulaire nécessite l'utilisation de modèles relativement simples où l'organisation tissulaire et les interactions susceptibles d'influencer l'évolution des cellules soient éliminées. Pour de telles études, les cultures de tissus végétaux ont d'abord fourni un type de matériel soustrait aux corrélations complexes de l'organisme entier. Les suspensions cellulaires au sein desquelles un assez haut degré de dispersion est atteint, répondent, semble-t-il, encore mieux à l'objectif désiré. En effet il s'agit là d'un système où l'on peut faire varier aisément un des facteurs de l'environnement et observer par la suite les réponses de division et de différenciation au niveau cellulaire. Le travail effectué au laboratoire sur ces problèmes avait été commencé sur des explants de parenchyme vasculaire de Topinambour. Dans le souci de mieux définir les conditions expérimentales, des supports de polyacrylamide aux caractéristiques définies avaient alors été adaptées à la culture in vitro. Sur ces gels, la croissance est modulée par la porosité. Ce caractère peut agir à la fois sur la disponibilité des éléments nutritifs et sur la diffusion de substances de différents poids relarguées par les tissus. Des conditions particulières sont ainsi créées au niveau des cellules de la zone de contact où s'effectuent les premières divisions.

Book Synopsis Cell Growth and Cell Division by : R. J. C. Harris
Download or read book Cell Growth and Cell Division written by R. J. C. Harris and published by Academic Press. This book was released on 2014-07-15 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell Growth and Cell Division is a collection of papers dealing with the biochemical and cytological aspects of cell development and changes in bacterial, plant, and animal systems. One paper discusses studies on the nuclear and cytoplasmic growth of ten different strains of the genus Blepharisma, in which different types of nutrition at high and low temperatures alter the species to the extent that they became morphologically indistinguishable. The paper describes the onset of death at high and low temperatures as being preceded by a decrease in the size of the cytoplasm and a corresponding decrease in the size of the macronucleus. The moribund organisms, still possessing structure, are motionless with no distinguishable macronuclear materials. Another paper presents the response of meiotic and mitotic cells to azaguanine, chloramphenicol, ethionine, and 5-methyltryptophan. The paper describes the failure of spindle action, arrest of second division, inhibition of cytokinesis, aberrant wall synthesis, and alterations in chromosome morphology in meiosis cells. In the case of mitosis, a single enzyme—thymidine phosphorylase—shows that reagents which inhibit protein synthesis also inhibit the appearance of that enzyme if the reagent is applied one day before it normally appears. Other papers discuss control mechanisms for chromosome reproduction in the cell cycle, as well as the force of cleavage of the dividing sea urchin egg. The collection can prove valuable for bio-chemists, cellular biologists, micro-biologists, and developmental biologists.

Book Synopsis Biology of Hevea Rubber by : P.M. Priyadarshan
Download or read book Biology of Hevea Rubber written by P.M. Priyadarshan and published by Springer. This book was released on 2017-06-09 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the second edition of this book, the origin, upkeep and latex harvest from the Hevea rubber tree are dealt with succinctly. New chapters have been included on Propagation Systems and Genetic Resources. The importance of Heterozygosis and Breeding is a new theme for the section on Breeding. A new chapter on Genomics and Molecular Breeding that focuses on the latest advancements on gene mapping, marker assisted selection and stimulation has been added. Lastly, ‘textboxes’ that highlight points and topics of significant interest are included in the new addition. Natural rubber has been an essential commodity not only for the tire industry but also for more than 50,000 products that holds elasticity as an attribute. The prime source of natural rubber worldwide is Hevea brasiliensis. Hevea rubber tree is an excellent example of how a soil-tree-atmosphere system can work in tandem. The retrieval of rubber through ‘injuring’ the tree on alternate days or once in three days or once in seven days, is indeed a unique arrangement followed universally that ensures income to the planter almost throughout the year. Every molecule of rubber is the end result of meticulous biochemical changes. Therefore the biology of Hevea rubber tree itself is a subject that aggregates science and technology for the realization of its industrial utility.

This book was released on 1986 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of a symposium organized by the IAEA and FAO, Vienna, 19-23 August 1985. The symposium examined the usefulness for plant breeding purposes of somaclonal variation, i.e. the occurrence of mutations during in vitro culture with or without the application of ionizing radiation or other mutagens. Another issue was finding ways and means of maintaining the genetic integrity of plants under in vitro conditions, such integrity being of vital importance if in vitro techniques are to be used to propagate virus-free clones of economically important plants, or to preserve germplasm in gene banks. In vitro culture techniques considerably accelerate the plant breeding cycle. This factor and the advantage of using haploids derived from another culture were also discussed at the symposium.
Book Synopsis Lipids and Lipid Polymers in Higher Plants by : M. Tevini

This book was released on 2012-12-06 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a number of papers dealing with the main topics of a Symposium on "Lipids and Lipid Polymers in Higher Plants", held in July 1976 at the Botanical Institute of the University of Karlsruhe. The symposium was organized by Professors E. Heinz, H.K. Lichtenthaler, H.K. Mangold, and M. Tevini. The sponsorship by the Deutsche Forschungsgemeinschaft and the Erwin-Riesch-Stiftung is gratefully acknowledged. The intention of the Symposium was to bring together in one place scientists working in very different fields of plant lipids, such as fatty acids, glycolipids, phospholipids, prenyllipids, sterols, and lipid polymers. The emphasis was placed on biosynthesis, distribution, function, and physiology of the various higher plant lipids and their role in biomembranes and epidermal cell walls. By combining the major contributions in this book, we hope to give all plant scientists access to the recent developments in biochemistry and physiology of plant lipid metabolism. The editors are very grateful to the contributors, who have taken great care to present up-to-date reviews. Karlsruhe, May 1977 M. TEVINI H.K. LICHTENTHALER Contents Section 1.

This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is generally accepted that photosynthesis, whereby solar is transformed into geobiochemical energy, is one of the most important processes in the bio sphere. When we realize that the human population, most of which is starving, wi I I double in 20-30 years, and that photosynthesis is in practice the only source (direct or indirect) of food not only for men, but for al I I iving beings, its im portance becomes even plainer. This fact was recognized from the outset of the International Biological Programme, when photosynthesis was selected as one of the principal problems to be concentrated on. The significance of the IBP in initiating a broader-based ap proach and worldwide collaboration need not be emphasized here; it is merely ne cessary to consider the rapid increase in the number of papers on photosynthesis since its inception. It is of fundamental importance for scientists working on photosynthesis to get information on what has been done in recent years in this discipl ine. Thus as complete as possible a bibl iography is badly needed. The complexity of this pro blem requires also that the progress of ecology, chemistry and physics, as far as they concern photosynthesis, be fol lowed. Such a bib I iography, covering at least the last ten years, wi I I be indispensable for final synthesis of the results of the IBP photosynthetic programme.

Book Synopsis Plant Cell Culture in Crop Improvement by : Kenneth Giles
Download or read book Plant Cell Culture in Crop Improvement written by Kenneth Giles and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current and potential importance of plant tissue culture techniques in crop improvement is hard to overemphasize. There are few areas where these techniques will have more possible im pact than in tropical agriculture, where the availability of high productivity varieties is sadly lacking in many species. The potential for the rapid, clonal propagation of elite individuals and the use of controlled multiline planting could have a major effect on crop yield and disease resistance in many areas of the world. This volume is a collection of papers presented at the Con ference on "Crop Improvement Through Tissue Culture", held at the Base Institute, Calcutta, India in December 1981. It attempts to bring together local research workers, familiar with the agri cultural resources of the area and tissue culture and molecular 4 level workers. It was the hope of the conference that the "cross fertilization" of ideas would lead to new approaches and activity in this area. The editors trust that this collection of papers will stimu~ late interest and research in the tissue culture and improvement of crop plants everywhere. v ACKNOWLEDGEMENTS The symposium from which the papers in this book are drawn was held at Bose Institute, Calcutta on December 6 to December 10, 1981.
