Landscapes, Genomics and Transgenic Conifers


Book Description

The book is written for policy experts, life scientists, government and business leaders, biotechnology writers and social activists. Few decision-makers realize the unprecedented degree to which transgenic technology is now possible for forests on a commercial scale. Only a handful of the 550 living conifer species is used for commodity value and even fewer species are being developed for transgenic plantations. Transgenic field trials started within the last decade but no transgenic pine plantations exist in 2005. But emergence of transgenic forest trees is still so recent that dialogue about the pros and cons is confined to the scientific community. And dialogue must move out into the public domain. The goal of this volume is to provide content for public deliberations about the genetic composition of future forests. Its Section I is composed of provocative and opposing views on the question of transgenic conifer plantations. Sections II and III follow with research advances on relevant conifer genomics and ecology research, respectively. Section IV forecasts rates of technology adoption for different case studies. Finally, Section V compares the status of regulatory oversight of transgenic forest trees between Canada and the United States.




Genetics, Genomics and Breeding of Conifers


Book Description

With contributions by internationally reputed researchers in the field, this book presents the implications of the genomic revolution for conifers—promoting a better understanding of the evolution of these organisms as well as new knowledge about the molecular basis of quantitative trait variation. Both of these discoveries play important roles in their domestication. Topics include cytogenetics, patterns of nucleotide diversity, genetic mapping, integration of molecular markers in breeding, transcriptomics, advances in proteomics and metabolomics in gymnosperms, and economic importance.




Genomics of Tree Crops


Book Description

Trees that are indispensably supportive to human life pose a formidable challenge to breed them to suit to human needs. From soft drinks to breweries to beverages to oil to tires, the value added products from trees give a spectrum of products to human kind. While attempts to tap these resources through conventional breeding are underway, the quick and elegant way of manipulating the genetic systems at the genome level is an essential chapter of modern science. Books featuring genomics of tree crops are few, and genomics is such a science that changes rapidly. Genomics of Tree Crops is an earnest attempt towards compiling genomics of tree crops. Plant genomics has made monumental strides in the last decade providing insights into intra-genomic phenomena such as heterosis, epistasis, pleiotropy and other interactions between loci and alleles within the genome. In contrast, the investigation of the roles and functions of single genes is a primary focus of molecular biology and is a common topic of modern genetic research. A genome is the sum total of all of an individual organism's genes. Thus, genomics is the study of all the genes of a cell, or tissue, at the DNA (genotype), mRNA (transcriptome), or protein (proteome) levels. The complete sequencing of the three billion base pair human genome with 25,000 genes identified and the invention of DNA microarrays ushered in a new era in the science of genomics leading to explosive advancements in oncology diagnostics. This impetus into the genomics era lead the way toward advances in plant genomics which started with Arabidopsis thaliana and went through an array of crops such as rice, maize, papaya, various cereals and legumes, with pigeon pea added to the list towards the end of 2011. Trees, on the other hand, are the least attended taxa with regard to genomic research. Some of the areas that attained attention of the scientists are: DNA sequencing, bioinformatics, genomics of flowering, gene flow, spatial structure, local adaptation and assisted migration in trees, transformation of fruit trees, genomics of tropical and temperate fruit trees, genomics of Hevea rubber, genomics of papaya and genomics of palms. Genomics of Tree Crops compiles this information with chapters authored by experts on these crops.




Conifer Reproductive Biology


Book Description

When it comes to reproduction, gymnosperms are deeply weird. Cycads and co- fers have drawn out reproduction: at least 13 genera take over a year from polli- tion to fertilization. Since they don’t apparently have any selection mechanism by which to discriminate among pollen tubes prior to fertilization, it is natural to w- der why such a delay in reproduction is necessary. Claire Williams’ book celebrates such oddities of conifer reproduction. She has written a book that turns the context of many of these reproductive quirks into deeper questions concerning evolution. The origins of some of these questions can be traced back Wilhelm Hofmeister’s 1851 book, which detailed the revolutionary idea of alternation of generations. This alternation between diploid and haploid generations was eventually to become one of the key unifying ideas in plant evolution. Dr. Williams points out that alter- tion of generations in conifers shows strong divergence in the evolution of male and female gametes, as well as in the synchronicity of male and female gamete development. How are these coordinated to achieve fertilization? Books on conifer reproduction are all too rare. The only major work in the last generation was Hardev Singh’s 1978 Embryology of Gymnosperms, a book that summarized the previous century’s work. Being a book primarily about embry- ogy, it stopped short of putting conifer reproduction in a genetic or evolutionary context.




Pines and Their Mixed Forest Ecosystems in the Mediterranean Basin


Book Description

Almost 20 years after the first MEDPINE book "Ecology, biogeography and management of Pinus halepensis and P. brutia forest ecosystems in the Mediterranean basin "(Ne'eman and Trabaud, 2000) was published, this new book presents up-to-date and state of the art information, covering a wide range of topics concerning Mediterranean pine trees growing in native and planted forests, their ecosystems and management. This will be an essential source of scientific information for learning, exploring planning and managing mediterranean pine and mixed forests. We focus on: genetics, adaptation, distribution and evolution; ecophysiology and drought resistance; pine and mixed forest ecosystems; forest dynamics biodiversity and biotic interactions; fire ecology; ecosystem services and policy; afforestation and management; all under the effect of global climate change. While forests are studied mainly in temperate and tropical zones, in the light of current climate change, focusing on Mediterranean forests growing in semi-humid to semi-arid zones is more important than ever. This book will include mostly review chapters (and two outstanding case studies) contributed by leading scientists, foresters and managers, and will serve as a scientific textbook for students of biology, agriculture and forestry, researchers of ecology forestry and related fields, forest managers, policy and decision makers.




Designing Green Landscapes


Book Description

While the natural resources of the earth continue to diminish, “Green Landscapes” arebeingcalleduponto produceanincreasingrangeofgoodsandservices.A Green Landscape is a rural expanse of scenery that may comprise a variety of visible f- tures. This book focuses on forested landscapes, although much of the theory and most of the practical applications are valid for any area of land. In many regions of the world, people depend on forests for their livelihood and well-being. Forests provide multiple services, – bene ts generated for society by the existence of c- tain forest ecosystems and their attributes. The value of these bene ts is often only recognised when they are lost after removal of the trees, resulting in ooding, loss of income and declining species diversity. Forests provide multiple services. However, the amount and quality, and the p- ticular mix of these services depend on the condition of the resource. Landscape design is a proven way to ensure that certain desired bene ts will be available in space and time. It provides the foundation and an essential starting point for s- tainable management. This volume, which forms part of Springer’s book series Managing Forest Ecosystems,presentsstate-of-the-artresearchresults,visionsandtheories,aswell as speci c methodsfor designing Green Landscapes, as a basis for sustainable ecos- tem management. The book contains a wealth of information which may be useful to companymanagement,the legal and policy environmentand forestry administ- tors. The volume is subdivided into four sections.

It presents a study of how herbicide treatments reduce fern densities and create the establishment of regeneration. It also analyzes an EST dataset from G. biloba that reveals genes potentially unique to gymnosperms and includes a study of episodic rate acceleration in the ancestral grasses.




Tree Transgenesis


Book Description

Tree improvement is necessary to meet the growing demand for renewable wood resource and the time is ripe for a critical evaluation of the chances and challenges of tree transgenesis. This book provides an up-to-date review of the present state of genetic engineering of trees. Biosafety and risk assessment are treated in detail, and future experimental tasks are discussed. The book provides a sound basis for decision-making processes in politics.




Tree Biotechnology


Book Description

Forest trees cover 30% of the earth's land surface, providing renewable fuel, wood, timber, shelter, fruits, leaves, bark, roots, and are source of medicinal products in addition to benefits such as carbon sequestration, water shed protection, and habitat for 1/3 of terrestrial species. However, the genetic analysis and breeding of trees has lagged behind that of crop plants. Therefore, systematic conservation, sustainable improvement and pragmatic utilization of trees are global priorities. This book provides comprehensive and up to date information about tree characterization, biological understanding, and improvement through biotechnological and molecular tools.
