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.

This book was released on 2021-08-31 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: To meet the global food demand of an increasing population, food production has to be increased by 60% by 2050. The main production constraints, such as climate change, biotic stresses, abiotic stresses, soil nutrition deficiency problems, problematic soils, etc., have to be addressed on an urgent basis. More than 50% of human calories are from three major cereals: rice, wheat, and maize. The harnessing of genetic diversity by novel allele mining assisted by recent advances in biotechnological and bioinformatics tools will enhance the utilization of the hidden treasures in the gene bank. Technological advances in plant breeding will provide some solutions for the biofortification, stress resistance, yield potential, and quality improvement in staple crops. The elucidation of the genetic, physiological, and molecular basis of useful traits and the improvement of the improved donors containing multiple traits are key activities for variety development. High-throughput genotyping systems assisted by bioinformatics and data science provide efficient and easy tools for geneticists and breeders. Recently, new breeding techniques applied in some food crops have become game-changers in the global food crop market. With this background, we invited 18 eminent researchers working on food crops from across the world to contribute their high-quality original research manuscripts. The research studies covered modern food crop genetics and breeding: plant molecular systems focusing to food crops; plant genetic diversity—QTL and gene identification utilizing high-throughput genotyping systems and their validation; new breeding techniques in food crops—targeted mutagenesis, genome editing, etc.; abiotic and biotic stresses—QTL/gene identification and their molecular physiology; plant nutrition, grain quality improvement, and yield enhancement.

Download or read book Nitrogen Use Efficiency Plant Biology to Crop Improvement written by Nandula Raghuram and published by Frontiers Media SA. This book was released on 2024-07-29 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The predominant role of unused fertilizers in reactive nitrogen pollution and the need for research and policies to improve nitrogen use efficiency (NUE) is now well known globally. NUE research was originally championed by the scientists of the International Nitrogen Initiative (INI) and later recognized by some national governments and UN agencies such as UNEP, FAO and UNECE. The resulting first ever UN resolution on “Sustainable nitrogen management” in 2019 boosted the demand for solutions, especially in agriculture. The Berlin Declaration from the INI 2021 conference called for improvement of nitrogen use efficiency towards achieving sustainable food systems and all the 17 sustainable development goals. Crop NUE is primarily a biological problem, as there exists a genetic limit to agronomic improvement. Overcoming this genetic barrier for crop improvement requires better understanding of the biological mechanisms of N-response and the genetic determinants of NUE. Fortunately, crop genomics in general and the functional genomics of N-response in particular have been providing a wealth of information. The recent developments in phenotyping and genotyping for NUE and the emergence of phenomics, coupled with the growing ability of bioinformatics to integrate diverse datasets offer unprecedented opportunities to solve the NUE puzzle. Some candidate genes for this multi-genic trait have been validated, while some others are being identified, shortlisted or offered for validation.

Download or read book Applications of Genetic Engineering to Crop Improvement written by G.B. Collins and published by Springer. This book was released on 2011-10-12 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contributions of plant genetics to the production of higher yielding crops of superior quality are well documented. These successes have been realized through the application of plant breeding techniques to a diverse array of genetically controlled traits. Such highly effective breeding procedures will continue to be the primary method employed for the development of new crop cultivars; however, new techniques in cell and molecular biology will provide additional approaches for genetic modification. There has been considerable speculation recently concerning the potential impact of new techniques in cell and molecular biology on plant improvement. These genetic engineering techniques should offer unique opportunities to alter the genetic makeup of crops if applied to existing breeding procedures. Many questions must be answered in order to identify specific applications of these new technologies. This search for applications will require input from plant scientists working on various aspects of crop improvement. This volume is intended to assess the interrelationships between conventional plant breeding and genetic engineering.

Download or read book Plant Breeding Past Present and Future written by John E. Bradshaw and published by Springer. This book was released on 2016-03-08 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to help plant breeders by reviewing past achievements, currently successful practices, and emerging methods and techniques. Theoretical considerations are also presented to strike the right balance between being as simple as possible but as complex as necessary. The United Nations predicts that the global human population will continue rising to 9.0 billion by 2050. World food production will need to increase between 70-100 per cent in just 40 years. First generation bio-fuels are also using crops and cropland to produce energy rather than food. In addition, land area used for agriculture may remain static or even decrease as a result of degradation and climate change, despite more land being theoretically available, unless crops can be bred which tolerate associated abiotic stresses. Lastly, it is unlikely that steps can be taken to mitigate all of the climate change predicted to occur by 2050, and beyond, and hence adaptation of farming systems and crop production will be required to reduce predicted negative effects on yields that will occur without crop adaptation. Substantial progress will therefore be required in bridging the yield gap between what is currently achieved per unit of land and what should be possible in future, with the best farming methods and best storage and transportation of food, given the availability of suitably adapted cultivars, including adaptation to climate change. My book is divided into four parts: Part I is an historical introduction; Part II deals with the origin of genetic variation by mutation and recombination of DNA; Part III explains how the mating system of a crop species determines the genetic structure of its landraces; Part IV considers the three complementary options for future progress: use of sexual reproduction in further conventional breeding, base broadening and introgression; mutation breeding; and genetically modified crops.

Download or read book Genetic Dissection of Maize Regeneration and Wheat Disease Resistance written by Guifang Lin and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing human population worldwide and the changing growth environments require significant crop improvement, which can be accelerated by plant genome engineering. Developing plant cultivars amenable to transformation and improving understanding of the genetic bases of important phenotypic traits can facilitate the use of advanced genome engineering technologies. This dissertation is focused on the genetic analysis of maize transformation and wheat resistance to the disease of leaf rust. The results will provide knowledge to improve crop transformation and wheat disease resistance. Plant transformation is a powerful tool for crop improvement and gene function validation. However, the transformation efficiency of maize is highly dependent on the tissue types and the genotypes. The maize inbred line A188 is amenable to transformation. A188 also exhibits many contrasting traits to the inbred line B73, which is recalcitrant to transformation. B73 was used to generate the first maize reference genome. The lack of genome sequences of A188 limits the use of A188 as a model for functional studies. Here, a chromosome-level genome assembly of A188 was constructed using long reads and optical physical maps. Genome comparison of A188 with B73 based on both whole genome alignments and sequencing read depths identified approximately 1.1 Gb syntenic sequences as well as extensive structural variation. Further, transcriptome and epigenome analyses with the A188 reference genome revealed enhanced gene expression of defense pathways and altered DNA methylation patterns of embryonic callus. The A188 genome assembly provides a foundational resource for analyses of genome variation and gene function in maize. In maize, morphologic types of calli induced from immature embryos are associated with the regeneration capability, which is a major factor determining the transformation efficiency. Here, two contrasting callus types, slow-growth type I calli and fast-growth type II calli, from the selected B73xA188 F2 population were sequenced using Genotyping-By-Sequencing (GBS) and RNA-Seq. With both approaches, the genomic loci associated with the callus type were mapped to chromosomes 2, 5, 6, 8, and 9. From F2 RNA-Seq, differentially expressed genes were identified from the comparison of type II and I calli. In addition, RNA-Seq analysis was performed using fast- and slow-growth calli identified for the A188 calli. Gene ontology (GO) enrichment analysis showed that the down-regulated genes in type II F2 calli and fast-growth A188 calli, as respectively compared to type I calli and slow-growth A188 calli, are overrepresented in the pathway related to cell wall organization, suggesting the role of cell wall formation in the callus development. Besides maize genetic and genomic studies, the dissertation includes the cloning of a leaf rust resistance gene in wheat. Wheat leaf rust disease is caused by a fungal pathogen, Puccinia triticina. The Lr42 gene from the wheat wild relative Aegilops tauschii confers resistance to all leaf rust races tested to date. Through bulked segregant RNA-Seq (BSR-Seq) mapping and further fine mapping, we identified an Lr42 candidate gene, which encodes a nucleotide-binding site leucine-rich repeat (NLR) protein. Transformation of the candidate gene to a leaf rust-susceptible wheat cultivar markedly enhanced the disease resistance, confirming the candidate NLR gene is the Lr42 gene. Cloning of Lr42 expands the repertoire of cloned rust resistance genes, as well as provides precise diagnostic gene markers for wheat improvement.

This book was released on 2020-12-18 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the holy grails in biology is the ability to predict functional characteristics from an organism's genetic sequence. Despite decades of research since the first sequencing of an organism in 1995, scientists still do not understand exactly how the information in genes is converted into an organism's phenotype, its physical characteristics. Functional genomics attempts to make use of the vast wealth of data from "-omics" screens and projects to describe gene and protein functions and interactions. A February 2020 workshop was held to determine research needs to advance the field of functional genomics over the next 10-20 years. Speakers and participants discussed goals, strategies, and technical needs to allow functional genomics to contribute to the advancement of basic knowledge and its applications that would benefit society. This publication summarizes the presentations and discussions from the workshop.

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.
