Book Synopsis Methods for Estimating Gamete Contributions to Orchard Seed Crops and Vegetative Lots in British Columbia by : Jack Herbert Woods
Download or read book Methods for Estimating Gamete Contributions to Orchard Seed Crops and Vegetative Lots in British Columbia written by Jack Herbert Woods and published by . This book was released on 2005 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods are described for estimating male and female gamete contributions from parent trees to conifer orchard seedlots1 and to vegetative lots in British Columbia. Methods are also described for estimating male gamete contributions for species and locations where contamination from non-orchard pollen is considered significant, and for calculating seedlot statistics when combining separate seedlots. These methods support the Chief Forester Standards for Seed Use (the Standards), developed under the Forest and Range Practices Act of British Columbia. For orchard seedlots and for vegetative lots, estimates of effective population size and genetic worth must be determined in accordance with formulae provided in the Standards. These formulae require male and female gamete contributions to be estimated for each parent tree, and from nonorchard pollen. The Standards refer to "generally accepted scientific methodology" for the estimation of male and female gamete contributions to orchard seedlots. This paper defines generally accepted methods. A number of methods are described and formulae provided for estimating male and female gamete contributions to seed and vegetative lots. Methods vary by expected precision and by application cost. Seed orchard managers should choose the method that best meets their needs.

Book Synopsis Gene Drives on the Horizon by : National Academies of Sciences, Engineering, and Medicine
Download or read book Gene Drives on the Horizon written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-08-28 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on gene drive systems is rapidly advancing. Many proposed applications of gene drive research aim to solve environmental and public health challenges, including the reduction of poverty and the burden of vector-borne diseases, such as malaria and dengue, which disproportionately impact low and middle income countries. However, due to their intrinsic qualities of rapid spread and irreversibility, gene drive systems raise many questions with respect to their safety relative to public and environmental health. Because gene drive systems are designed to alter the environments we share in ways that will be hard to anticipate and impossible to completely roll back, questions about the ethics surrounding use of this research are complex and will require very careful exploration. Gene Drives on the Horizon outlines the state of knowledge relative to the science, ethics, public engagement, and risk assessment as they pertain to research directions of gene drive systems and governance of the research process. This report offers principles for responsible practices of gene drive research and related applications for use by investigators, their institutions, the research funders, and regulators.

Book Synopsis Pollination Biology by : Dharam P. Abrol
Download or read book Pollination Biology written by Dharam P. Abrol and published by Springer Science & Business Media. This book was released on 2011-10-05 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has a wider approach not strictly focused on crop production compared to other books that are strictly oriented towards bees, but has a generalist approach to pollination biology. It also highlights relationships between introduced and wild pollinators and consequences of such introductions on communities of wild pollinating insects. The chapters on biochemical basis of plant-pollination interaction, pollination energetics, climate change and pollinators and pollinators as bioindicators of ecosystem functioning provide a base for future insights into pollination biology. The role of honeybees and wild bees on crop pollination, value of bee pollination, planned honeybee pollination, non-bee pollinators, safety of pollinators, pollination in cages, pollination for hybrid seed production, the problem of diseases, genetically modified plants and bees, the role of bees in improving food security and livelihoods, capacity building and awareness for pollinators are also discussed.

Book Synopsis Introduction to Forest Genetics by : Jonathan Wright
Download or read book Introduction to Forest Genetics written by Jonathan Wright and published by Elsevier. This book was released on 2012-12-02 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Forest Genetics examines some of the basic genetic concepts typically used in forestry and tree improvement studies, including Mendelian and population genetics. It also describes techniques that are generally useful in tree improvement work, including individual tree selection and breeding, provenance testing, species and racial hybridization, and introduction of exotics. Organized into 19 chapters, this volume begins with an overview of forest genetics and problems associated with forest genetics. It then discusses concepts from basic genetics, including chromosome structure and function; DNA and RNA; nongenetic inheritance; and genotype versus phenotype. Other chapters focus on inbreeding: complete elimination of homozygous recessive trees; mutation and migration; and controlled pollination and vegetative propagation. The book also covers the establishment and measurement of test plantations; general principles and methods of selective breeding; choice of breeding method and type of seed orchard; heritability and genetic gain; geographic variation in Scotch pine and American trees; species and racial hybridization; chromosome studies; and polyploidy and haploidy breeding. This book is a valuable resource for foresters, professional tree breeders, and those with or without previous training in genetics or forestry.
