Book Synopsis Towards a Genome Sequence of the Brown Spot Needle Blight Pathogen (Mycosphaerella Dearnessii) Infecting Longleaf Pine by : Benjamin Douglas Bartlett
Download or read book Towards a Genome Sequence of the Brown Spot Needle Blight Pathogen (Mycosphaerella Dearnessii) Infecting Longleaf Pine written by Benjamin Douglas Bartlett and published by . This book was released on 2015 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major disease damaging seedlings of Pinus palustris is caused by the fungus Mycosphaerella dearnessii. Population structure of this pathogen was studied in a population in Mississippi. High genetic diversity (0.65) was measured using microsatellite markers and coincides with the high number of vegetative compatibly groups observed. A 30 Mb genome sequence for a single isolate of M. dearnessii was assembled, representing 65% of the estimated genome size. Nearly all (93%) of the core set of genes present in eukaryotes were detected from a total of 10,996 predicted genes. A total of 853 enzymatic associations were identified along with several genes homologous to pathogenic genes in other fungal pathogens. These results provide insights into the infection process and host-pathogen interactions. Further investigating this pathosystem will lead to effective disease management strategies.

Download or read book Plant Pathology written by George Agrios and published by Elsevier. This book was released on 2012-12-02 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Pathology presents information and advances in plant pathology including disease induction and development and disease resistance and control. This book is organized into two major parts encompassing 14 chapters that focus on diseases, pathogenicity, and pathogen variability. The first part of the book deals with general considerations of disease, the disease cycle, parasitism and pathogenicity, and the variability in pathogens. This is followed by a presentation of the mechanisms by which pathogens cause disease and plants resist disease. Core chapters focus on the effects of pathogen-produced enzymes, toxins, growth regulators, and polysaccharides on the structural organization and on the basic physiological processes of photosynthesis, translocation, and respiration. The chapters also discuss the defense mechanisms of the plant. Moreover, this book explains the genetics of host-parasite interaction, effects of environment on disease development, and control. The second part of the book deals with the infectious diseases caused by fungi, bacteria, parasitic higher plants, viruses, and nematodes. This part also looks into the noninfectious diseases caused by environmental factors. The diseases caused by each type of pathogen are discussed comprehensively as a group and are subsequently discussed individually in detail. This book includes diagrams of cycles for each disease to create visual images for better understanding of the disease and message retention. This book is ideal for students with introductory course in plant pathology.

Book Synopsis Vascular Differentiation and Plant Growth Regulators by : Lorin W. Roberts
Download or read book Vascular Differentiation and Plant Growth Regulators written by Lorin W. Roberts and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of the book is to provide an up-to-date examination of the possible roles of plant hormones during the cytodifferentiation of xylem and phloem elements in higher plants. Various facets of vascular differentiation, as cell determination, cell cycle activity, and the biochemical events in xylogenesis, are analyzed. Furthermore, the latest information on the roles of auxins, cytokinins, gibberellins, ethylene, and abscisic acid during vascular cell formation are summarized. A theoretical discussion of the six-point hypothesis and the vascular adaptation hypothesis is included. The experimental induction of vascular differentiation under tissue culture conditions is critically appraised and a concluding chapter covers the interactions between physical factors, growth regulators, and differentiation.
Book Synopsis Utilization of Residual Forest Biomass by : Pentti Hakkila
Download or read book Utilization of Residual Forest Biomass written by Pentti Hakkila and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: An increase in the demand for wood results in improved recovery and less residual biomass in the forests. Paradoxically, interest in forest residue as a renewable source of raw material seems to be in a reverse ratio to its availability in a certain area. Finland and Sweden are probably more dependent on forestry and forest in dustries than any other developed countries in the world. A sufficiency of raw ma terial for integrated forest industries is vital for the national economy of both countries, and a great deal of attention is being paid to the long-term potential of unutilized biomass left behind in logging operations. Furthermore, since these countries possess no reserves of fossil fuels, and since their per-capita consump tion of primary energy is exceptionally high, they also consider unmerchantable forest biomass a realistic source of indigenous energy. A joint Nordic research project on harvesting and utilization of logging residue was carried out in 1969-1976 under the auspices of the Nordic Research Council on Forest Operations. This fruitful cooperation soon gave rise to related national projects in Sweden, Finland, Norway, and Denmark, stimulating further research and producing practical applications. Concurrently, particularly after the worldwide energy crisis in 1973, research on all aspects of utilization of forest bio mass mushroomed in the United States, Canada, and the Soviet Union. An ex plosive increase occurred in both the number and diversity of biomass studies.

Book Synopsis Growth Stresses and Strains in Trees by : Robert R. Archer
Download or read book Growth Stresses and Strains in Trees written by Robert R. Archer and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although over 40 years have passed since Jacobs (1945) convincingly established the basic radial pattern of residual growth stress in growing trees, yet this phenomenon is still not widely appreciated in wood science and technology circles. This is in spite of the fact that the presence of these stresses of sizeable magnitudes has long been recognized as a primary cause of shakes and splits in logs as well as the warping of lumber sawn in the green condition. The presentation of the subject of growth stresses in trees presents some special problems due to the wide range of specialists who potentially might have an interest in the subject. For example, tree physiologists interested in questions such as the relation of mechanical stress to stem taper and the role of reaction wood and gravity forces in determining tree crown form encounter growth stress models. Silvi culturists interested in the relation ofthinning practices to wood quality find that wood properties are correlated with growth stress levels which are in turn significantly changed by cutting practices. Wood techno logists interested in the relation of residual growth stress gradients in green logs to the dimensional quality of sawn and seasoned lumber are forced to take a more quantitative approach to the effect of growth stresses than might have been the case in the past.
Book Synopsis Natural Products of Woody Plants by : John W. Rowe
Download or read book Natural Products of Woody Plants written by John W. Rowe and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood as found in trees and bushes was of primary importance to ancient humans in their struggle to control their environment. Subsequent evolution through the Bronze and Iron Ages up to our present technologically advanced society has hardly diminished the importance of wood. Today, its role as a source of paper products, furniture, building materials, and fuel is still of major significance. Wood consists of a mixture of polymers, often referred to as lignocellulose. The cellulose micro fibrils consist of an immensely strong, linear polymer of glucose. They are associated with smaller, more complex polymers composed of various sugars called hemicelluloses. These polysaccharides are embedded in an amorphous phenylpropane polymer, lignin, creating a remarkably strong com posite structure, the lignocellulosic cell wall. Wood also contains materials that are largely extraneous to this lignocellulosic cell wall. These extracellular substances can range from less than 1070 to about 35% of the dry weight of the wood, but the usual range is 2% -10%. Among these components are the mineral constituents, salts of calcium, potassium, sodium, and other metals, particularly those present in the soil where the tree is growing. Some of the extraneous components of wood are too insoluble to be ex tracted by inert solvents and remain to give extractive-free wood its color; very often these are high-molecular-weight polyphenolics.
