This book was released on 2024-01-18 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Orphan crops play an important role in food and nutrition security especially in growing economies where small-holder farmers produce the majority of food. Despite their importance in global agriculture and their often remarkable nutrient content and adaptation to challenging environmental conditions, orphan crops have received limited attention by the scientific community and industry. However, the diversity of neglected plant species provides a large genetic resource that could significantly contribute to broadening the biodiversity of trait-desired crops for novel value chains, sustainable development and food security. The uptake of new plant breeding techniques, notably genome editing, as well as ‘omic’ tools, are now accelerating translation of basic research and facilitating the exploration of orphan crops. These advancements also give rise to public and politic engagement discussions to maximize socio-economic impact. Given that the greatest need for food and nutritional security is in growing economies, issues of food sovereignty and sustainability of their food systems become front-and-centre. There is now an exceptional opportunity to tackle some of the major current challenges in agriculture, including climate change, sustainable cropping systems, food quality, and nutritional security through broadening research in wild relatives of crops and on orphan species. This Research Topic seeks to showcase research on neglected plants using advanced molecular technologies (e.g. genome sequencing, 'omics', etc) and new plant breeding approaches, methods, and tools. This Research Topic will also discuss the challenges and opportunities arising when modern breeding techniques are applied for translational research.

Available in PDF, EPUB and Kindle. Book excerpt: Cotton, the most important natural fiber crop, has been improved by conventional breeding—largely through planned hybridization of different cotton genotypes, since the discovery of Mendelian genetics. All these efforts resulted in the development of resilient high yielding cotton varieties. However, the progress through conventional breeding procedures is slow because of long lag periods for developing a variety, little control over the new genetic combinations, unwanted traits and lack of foolproof performance testing system. Genomic assays discovered over the last two decades have made it possible to understand the “language” of the genome by associating the genes with specific traits. Together with the more recently established gene-editing tools like CRISPR-Cas9, the cotton genome can be tailored much more precisely than ever before. In this regard, genetic information has been harnessed, through (i) sequencing of the progenitor and cultivated cotton species, (ii) ongoing mega pan-genome sequencing projects, (iii) genetic and physical mapping, and (iv) introgression of genes from alien sources, that resulted in the development of resilient cotton cultivars. These technologies have been deployed or are attempting to overcome the challenges of water shortage, excessive heat in most cotton growing regions, infectious diseases and infestation of insect pests, as well as rising production cost, for sustainable cotton production beyond 2030. In this book, new knowledge generated by the cotton research community and its application for developing resilient cotton are comprehensively summarized. This book contributed by well-known cotton researchers is a timely collection of the challenges and successes of precision cotton breeding in a changing environment.

Download or read book The Applications of New Multi Locus GWAS Methodologies in the Genetic Dissection of Complex Traits written by Yuan-Ming Zhang and published by Frontiers Media SA. This book was released on 2019-06-19 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genome-Wide Association Studies (GWAS) are widely used in the genetic dissection of complex traits. Most existing methods are based on single-marker association in genome-wide scans with population structure and polygenic background controls. To control the false positive rate, the Bonferroni correction for multiple tests is frequently adopted. This stringent correction results in the exclusion of important loci, especially for GWAS in crop genetics. To address this issue, multi-locus GWAS methodologies have been recommended, i.e., FASTmrEMMA, ISIS EM-BLASSO, mrMLM, FASTmrMLM, pLARmEB, pKWmEB and FarmCPU. In this Research Topic, our purpose is to clarify some important issues in the application of multi-locus GWAS methods. Here we discuss the following subjects: First, we discuss the advantages of new multi-locus GWAS methods over the widely-used single-locus GWAS methods in the genetic dissection of complex traits, metabolites and gene expression levels. Secondly, large experiment error in the field measurement of phenotypic values for complex traits in crop genetics results in relatively large P-values in GWAS, indicating the existence of small number of significantly associated SNPs. To solve this issue, a less stringent P-value critical value is often adopted, i.e., 0.001, 0.0001 and 1/m (m is the number of markers). Although lowering the stringency with which an association is made could identify more hits, confidence in these hits would significantly drop. In this Research Topic we propose a new threshold of significant QTN (LOD=3.0 or P-value=2.0e-4) in multi-locus GWAS to balance high power and low false positive rate. Thirdly, heritability missing in GWAS is a common phenomenon, and a series of scientists have explained the reasons why the heritability is missing. In this Research Topic, we also add one additional reason and propose the joint use of several GWAS methodologies to capture more QTNs. Thus, overall estimated heritability would be increased. Finally, we discuss how to select and use these multi-locus GWAS methods.

This book was released on 2023-12-28 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in next-generation sequencing-driven mass production of genomic data and various other integrated techniques have considerably broadened and deepened our understanding of living organisms' molecular systems. Because complex quantitative traits are difficult to select due to low heritability, conventional plant breeding relies on phenotypic selection and breeder experience, it takes longer to develop a new, improved variety. For association studies to identify DNA markers linked to these complex traits, genotyping chip arrays allow genotyping of thousands of markers in a short amount of time. Plant breeding consistency and predictability have improved thanks to advances in genomics. NGS technologies bring new tools and concepts that can enhance the precision and efficiency of plant breeding such as cost-effective, high throughput genotyping technologies for sustainable agriculture. These genotyping technologies will be lowering the time and cost of developing high-quality food crops that are stress-resistant while still having a high nutritional value. This Research Topic focuses on recent advancements in NGS-related technologies, mainly the development of cost-effective high-throughput genotyping platforms with a wide range of bioinformatics tools, and possible translational multi-omics applications in crop breeding programs for sustainable agriculture.
