Book excerpt: This book is open access under a CC BY 4.0 license. This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compared with commodity crops such as maize, wheat or rice. On the other, it provides an effective insulation against speculation and unforeseen spikes in commodity prices, since the potato does not represent a good traded on global markets. These two factors highlight the underappreciated and underrated role of the potato as a dependable nutrition security crop, one that can mitigate turmoil in world food supply and demand and political instability in some developing countries. Increasingly, the global role of the potato has expanded from a profitable crop in developing countries to a crop providing income and nutrition security in developing ones. This book will appeal to academics and students of crop sciences, but also policy makers and other stakeholders involved in the potato and its contribution to humankind’s food security.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes the historical importance of potato (Solanum tuberosum L.),potato genetic resources and stocks (including S. tuberosum group Phureja DM1-3 516 R44, a unique doubled monoploid homozygous line) used for potato genome sequencing. It also discusses strategies and tools for high-throughput sequencing, sequence assembly, annotation, analysis, repetitive sequences and genotyping-by-sequencing approaches. Potato (Solanum tuberosum L.; 2n = 4x = 48) is the fourth most important food crop of the world after rice, wheat and maize and holds great potential to ensure both food and nutritional security. It is an autotetraploid crop with complex genetics, acute inbreeding depression and a highly heterozygous nature. Further, the book examines the recent discovery of whole genome sequencing of a few wild potato species genomes, genomics in management and genetic enhancement of Solanum species, new strategies towards durable potato late blight resistance, structural analysis of resistance genes, genomics resources for abiotic stress management, as well as somatic cell genetics and modern approaches in true-potato-seed technology. The complete genome sequence provides a better understanding of potato biology, underpinning evolutionary process, genetics, breeding and molecular efforts to improve various important traits involved in potato growth and development.
Download or read book Genetic Data Analysis for Plant and Animal Breeding written by Fikret Isik and published by Springer. This book was released on 2017-09-09 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book fills the gap between textbooks of quantitative genetic theory, and software manuals that provide details on analytical methods but little context or perspective on which methods may be most appropriate for a particular application. Accordingly this book is composed of two sections. The first section (Chapters 1 to 8) covers topics of classical phenotypic data analysis for prediction of breeding values in animal and plant breeding programs. In the second section (Chapters 9 to 13) we provide the concept and overall review of available tools for using DNA markers for predictions of genetic merits in breeding populations. With advances in DNA sequencing technologies, genomic data, especially single nucleotide polymorphism (SNP) markers, have become available for animal and plant breeding programs in recent years. Analysis of DNA markers for prediction of genetic merit is a relatively new and active research area. The algorithms and software to implement these algorithms are changing rapidly. This section represents state-of-the-art knowledge on the tools and technologies available for genetic analysis of plants and animals. However, readers should be aware that the methods or statistical packages covered here may not be available or they might be out of date in a few years. Ultimately the book is intended for professional breeders interested in utilizing these tools and approaches in their breeding programs. Lastly, we anticipate the usage of this volume for advanced level graduate courses in agricultural and breeding courses.
Download or read book Advancing Diploid Potato Breeding Through Genetic Analysis and Genomic Selection written by Lin Song (Ph.D.) and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Breeding gains of commercial autotetraploid potato (Solanum tuberosum L.) have been limited by tetrasomic inheritance for centuries. After mapping a self-compatible gene (Sli) on chromosome 12 at the end of the 20th century, the breeding strategy has shifted towards developing diploid inbred lines that can generate F1 hybrid varieties through sexual hybridization. Overcoming the gametophytic self-incompatibility through Sli is the first step in breeding at the diploid level. Then self-fertilization is performed within each breeding cycle to achieve pure diploid inbred lines. However, reaching full homozygosity is made difficult by severe inbreeding depression in potato. As a result, multiple hybridization events are needed to break linkages with the deleterious alleles. This research aims to create the germplasm and provide the data for future diploid potato breeding. We first focused on genes that were well characterized in potato: Sli and the vine maturity gene StCDF1 (Cycling DOF Factor 1). A modified backcrossing scheme using primary dihaploids of Solanum tuberosum as the recurrent parental background allowed for the selection of self-fertile F2 individuals homozygous for Sli. By integrating haplotype and quantitative trait locus (QTL) analysis, we identified and selected partially inbred lines fixed for the two favorable alleles. They were used to initiate new cycles of selection with the goal of increasing homozygosity while maintaining plant vigor, fertility, and yield. Then we sought to discover new genetic variants by genome-wide association study (GWAS) and joint linkage mapping. Two years of field trials were performed at the Hancock Agricultural Research Station (HARS), WI, using the progeny from Backcross Cycles 1 and 2 (BC1, BC2) in the years 2020 and 2021. The traits evaluated were vine maturity, tuber appearance, tuber yield, tuber size, specific gravity, chip color, and tuber sprouting. 25 significant QTL, including CDF1 and the tuber shape gene StOFP20, were identified in GWAS. Through joint linkage mapping with connected outbred F1 progeny in the 2021 field trial, we determined the three most desirable OFP20 haplotypes for round tuber shape. We further explored the potential of utilizing genomic selection for diploid potato with the two-year field trial data. The narrow-sense heritability estimates ranged from 0.41 to 0.63. Tuber yield showed the highest prediction reliability for marker-assisted genomic selection at 0.78. Both additive and dominance effects were included in the model, and dominance was most important for tuber yield, explaining 12% of the variance through heterosis. We have also discovered that, despite lower prediction accuracy, the historical tetraploid data can be used as a training population to predict traits of diploid potatoes. The prediction ability for diploids with the mixed ploidy training population ranged from 0.1 to 0.3.

Available in PDF, EPUB and Kindle. Book excerpt: This Research Topic addresses research in genomics and biotechnology to improve the growth and quality of forest trees for wood, pulp, biorefineries and carbon capture. Forests are the world’s greatest repository of terrestrial biomass and biodiversity. Forests serve critical ecological services, supporting the preservation of fauna and flora, and water resources. Planted forests also offer a renewable source of timber, for pulp and paper production, and the biorefinery. Despite their fundamental role for society, thousands of hectares of forests are lost annually due to deforestation, pests, pathogens and urban development. As a consequence, there is an increasing need to develop trees that are more productive under lower inputs, while understanding how they adapt to the environment and respond to biotic and abiotic stress. Forest genomics and biotechnology, disciplines that study the genetic composition of trees and the methods required to modify them, began over a quarter of a century ago with the development of the first genetic maps and establishment of early methods of genetic transformation. Since then, genomics and biotechnology have impacted all research areas of forestry. Genome analyses of tree populations have uncovered genes involved in adaptation and response to biotic and abiotic stress. Genes that regulate growth and development have been identified, and in many cases their mechanisms of action have been described. Genetic transformation is now widely used to understand the roles of genes and to develop germplasm that is more suitable for commercial tree plantations. However, in contrast to many annual crops that have benefited from centuries of domestication and extensive genomic and biotechnology research, in forestry the field is still in its infancy. Thus, tremendous opportunities remain unexplored. This Research Topic aims to briefly summarize recent findings, to discuss long-term goals and to think ahead about future developments and how this can be applied to improve growth and quality of forest trees.

Download or read book Genome Engineering for Crop Improvement written by Bidyut Kumar Sarmah and published by Springer Nature. This book was released on 2021-04-18 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book serves the teachers, researchers and the students as a handy and concise reference as well as guidebook while designing and planning for use of the advanced technologies for crop improvement. The content of the book is designed to cover the latest genome engineering techniques for crop improvement. The conventional breeding has got its limitations such as non-availability of desired genes within the genepool. In many cases, breeding has been highly used and it has nearly reached its highest limit so far as the productivity and production of crops are concerned. However, with increasing need of food and decreasing resources, including water, land, labour, etc., to feed the growing population, the alternative available ways of increasing crop productivity need to be explored and exploited. Genome engineering has a wide scope that includes technologies such as genetic engineering and transgenesis, RNA technologies, CRISPR, cisgenics and subgenics for better productivity and more efficient biotic and abiotic stress management. Therefore, the book is planned to enlighten the readers with the advanced technologies with examples and case studies, whenever possible. Efforts will be made to emphasize on general efforts on various major food crops; however, it would also be made clear that such efforts could be taken as proofs of concepts and that this could be extrapolated keeping the demand in mind.
