Available in PDF, EPUB and Kindle. Book excerpt: This laboratory is committed to understanding the function of plant peroxidases via a multi-disciplinary approach. We have chosen the lignin-forming peroxidase from tobacco as the first isoenzyme to be subjected to this comprehensive approach. The goals which were set out upon the initiation of this project were as follows: (1) utilize a cDNA clone to the tobacco anionic peroxidase to generate transgenic plants which either over-produced this isoenzyme or specifically under-produced this isoenzyme via antisense RNA, (2) describe any phenotypic changes resulting from altered peroxidase expression, (3) perform morphological, physiological, and biochemical analysis of the above mentioned plants to help in determining the in planta function for this enzyme, and (4) clone and characterize the gene for the tobacco anionic peroxidase. A summary of progress thus far which includes both published and unpublished work will be presented in three sections: generation and characterization of transgenic plants, description of phenotypes, and biochemical and physiological analysis of peroxidase function, and cloning and characterization of the tobacco anionic peroxidase gene.

This book was released on 1995 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: My research program focuses entirely on the study of the lignin-forming peroxidase of tobacco. Ever since our cloning and sequencing of the first plant peroxidase cDNA, we have pioneered in the introduction of the tools of molecular biology to the study of plant peroxidases. A significant part of our effort has been focused on the construction and analysis of transgenic plants which either over- or under-express the tobacco anionic peroxidase. This research has not only supported the role for this enzyme in lignification, but has opened the door to our understanding of additional metabolic functions including auxin metabolism and insect defense. As you will learn, this enzyme's role in auxin catabolism has lead to numerous phenotypes in transgenic plants. More recently, our attention has been directed towards the analysis of peroxidase gene expression. From this work we have learned that the anionic peroxidase gene is expressed at high levels in the xylem-forming cells, epidermis, and trichomes. This expression pattern supports its role lignification and hose defenses. We have also learned that this gene is down-regulated by auxin which indicates a strong relationship between auxin and the anionic peroxidase. 12 figs.

Available in PDF, EPUB and Kindle. Book excerpt: This laboratory has continued its comprehensive study of the structure and function of plant peroxidases and their genes. Specifically, we are characterizing the anionic peroxidase of tobacco. During the past year we have completed the nucleotide sequence of the tobacco anionic peroxidase gene, joined the anionic peroxidase promoter to [Beta]-glucuronidase and demonstrated expression in transformed plants, measured lignin, auxin, and ethylene levels in transgenic tobacco plants over-expressing the anionic peroxidase, developed chimeric peroxidase genes to over-or under-express the anionic peroxidase in tissue specific manner in transgenic plants, and over-expressed the tobacco anionic peroxidase in transgenic tomato and sweetgum plants.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Our group continues to focus on the characterization of the tobacco anionic peroxidase and its genes. Throughout this past year we have generated transgenic plants expressing [beta]-glucuronidase under control of the anionic peroxidase promoter, characterized effectors of peroxidase gene expression in transformed protoplasts, generated numerous transgenic plants which over- and under-express the anionic peroxidase in a tissue specific manner, characterized the role of the anionic peroxidase in the metabolism of auxin, introduced a marker (flag) into the anionic peroxidase primary protein sequence which will permit the identification of the recombinant protein in plant tissue, and described the enhancement of insect resistance as a result of over-expression of the anionic peroxidase. Although our research program has continued along the lines of the original proposal, we have redirected a significant effort to the role which this enzyme plays in the metabolism of auxin, and conversely, the role which auxin plays in regulating the expression of the anionic peroxidase gene.

Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the 2nd edition, there have been substantial developments in the field of litter decomposition. This fully revised and updated 3rd edition of Plant Litter reflects and discusses new findings and re-evaluates earlier ones in light of recent research and with regard to current areas of investigation. The availability of several long-term studies allows a more in-depth approach to decomposition patterns and to the later stages of decomposition, as well as to humus formation and accumulation. The latest information focuses on three fields: - the effects of manganese on decomposition and possibly on carbon sequestration, - new findings on decomposition dynamics, and - the new analytical technique using 13C-NMR.

Available in PDF, EPUB and Kindle. Book excerpt: At present, plants and agricultural sciences are playing a leading role in providing solutions to problems created by an ever growing world population. Through plant biotechnology scientists are seeking ways to improve crop functions that rapidly promote food production. Agricultural science is being used to experiment with producing plants tolerant to environmental stresses such as drought, salinity and coldness. Of the plant species, woody plants are producing the most abundant biomass resources, playing important roles in the suppression of carbon dioxide increase and supplying huge energy and resources to human beings in the biosphere. These Proceedings discuss the recent results of fundamental and applied research for global resource and energy, biomass production and environmental problems from the aspect of woody science. Topics include: - Formation of the vascular bundle - Biosynthesis of cellulose - Lignin biosynthesis and transgenic woody plants - Cell and tissue culture, and transformation in gymnosperms - Micropropagation of woody plants

Download or read book Biochemistry and Molecular Biology of Wood written by Takayoshi Higuchi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in wood chemistry has been related mainly to chemical wood pulping and bleaching and chemical utilization of wood and wood extractives. Meth ods of wood analysis were developed by Schorger (proximate analysis in 1917) and Dore (summative analysis in 1919), and standard methods based on Schorger's method, e.g., TAPPI standards (Technical Association of the Pulp and Paper Industry), have been widely used for chemical analysis of woods in many countries. Thus it is generally known that wood is composed of about 50% cellulose, 20-35% of lignin, 15-25% of hemicelluloses, and variable amounts of extractives. Chemical characterization and efficient utilization of these wood components have been studied in laboratories of wood chemistry and technology in universities and government institutions. In the last decade, biochemistry and molecular biology of microorganisms, animals, and plants have greatly progressed. At the same time wood has been recognized as a unique renewable ecomaterial produced by trees using solar energy. In addition, many desirable properties of wood and wood components as biomaterial that affects physiology and psychology in humans have recently attracted attention.
