Book excerpt: Our objectives were to apply bioinformatics and high throughput sequencing technologies to identify and classify the genes involved in cell wall formation in maize and switchgrass. Targets for genetic modification were to be identified and cell wall materials isolated and assayed for enhanced performance in bioprocessing. We annotated and assembled over 750 maize genes into gene families predicted to function in cell wall biogenesis. Comparative genomics of maize, rice, and Arabidopsis sequences revealed differences in gene family structure. In addition, differences in expression between gene family members of Arabidopsis, maize and rice underscored the need for a grass-specific genetic model for functional analyses. A forward screen of mature leaves of field-grown maize lines by near-infrared spectroscopy yielded several dozen lines with heritable spectroscopic phenotypes, several of which near-infrared (nir) mutants had altered carbohydrate-lignin compositions. Our contributions to the maize genome sequencing effort built on knowledge of copy number variation showing that uneven gene losses between duplicated regions were involved in returning an ancient allotetraploid to a genetically diploid state. For example, although about 25% of all duplicated genes remain genome-wide, all of the cellulose synthase (CesA) homologs were retained. We showed that guaiacyl and syringyl lignin in lignocellulosic cell-wall materials from stems demonstrate a two-fold natural variation in content across a population of maize Intermated B73 x Mo7 (IBM) recombinant inbred lines, a maize Association Panel of 282 inbreds and landraces, and three populations of the maize Nested Association Mapping (NAM) recombinant inbred lines grown in three years. We then defined quantitative trait loci (QTL) for stem lignin content measured using pyrolysis molecular-beam mass spectrometry, and glucose and xylose yield measured using an enzymatic hydrolysis assay. Among five multi-year QTL for lignin abundance, two for 4-vinylphenol abundance, and four for glucose and/or xylose yield, not a single QTL for aromatic abundance and sugar yield was shared. A genome-wide association study (GWAS) for lignin abundance and sugar yield of the 282-member maize Association Panel provided candidate genes in the eleven QTL and showed that many other alleles impacting these traits exist in the broader pool of maize genetic diversity. The maize B73 and Mo17 genotypes exhibited surprisingly large differences in gene expression in developing stem tissues, suggesting certain regulatory elements can significantly enhance activity of biomass synthesis pathways. Candidate genes, identified by GWAS or by differential expression, include genes of cell-wall metabolism, transcription factors associated with vascularization and fiber formation, and components of cellular signaling pathways. Our work provides new insights and strategies beyond modification of lignin to enhance yields of biofuels from genetically tailored biomass.

Download or read book The Improvement of Yield Limiting Switchgrass Panicum Virgatum L Traits Through Genomic Prediction and Selection written by Neal Wepking Tilhou and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genomic prediction allows the estimation of breeding values for individuals in a breeding program using molecular markers. In plant breeding, this can improve the precision of field evaluations or even allow a breeder to bypass time-intensive field evaluations altogether. Switchgrass is a candidate bioenergy crop which must be rapidly developed and deployed to mitigate climate change caused by excess carbon emissions. Switchgrass is a long-lived perennial with slow selection cycles (4-6 years), therefore accurate genomic prediction of yield or yield surrogates will be valuable for rapid cultivar development. This dissertation presents multiple applications of genomic prediction which can accelerate yield improvement in switchgrass. The first chapter is a review of recent developments of bioenergy, switchgrass agronomy, and genomic prediction. The second chapter evaluates genomic prediction of flowering time to improve biomass yield. It found limited value in sharing information between diverged switchgrass breeding populations, but that genomic prediction within breeding populations had strong predictive ability (0-43-0.90) and flowering time predictions were able to accurately rank individuals evaluated for biomass yield (0.38-0.63). The third chapter evaluated genomic prediction for winter survivorship on crosses from diverse, winter-intolerant populations. Again, genomic prediction was able to accurately predict winter survivorship in a progeny population (predictive ability = 0.71) and this chapter further reinforced that winter tolerant populations from the southern United States have strong biomass yield potential in the north-central United States. The fourth chapter presents simulations which tested pooled sequencing of DNA samples as a strategy to reduce the expense of adopting genomic prediction. Overall, pooling samples of individuals evaluated in the field and individuals sequenced to obtain predictions consistently resulted in reduced predictive ability. However, this loss in accuracy was often minor relative to the substantial cost savings provided by pooled DNA sequencing. In resource constrained scenarios, this study found multiple routes where DNA pooling could increase breeding progress. The research presented in this dissertation highlights multiple new breeding strategies and methods for integrating genomic prediction methods into switchgrass and other breeding programs with limited resources.

This book was released on 2008-04-20 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life on Earth would be impossible without plants. Humans rely on plants for most clothing, furniture, food, as well as for many pharmaceuticals and other products. Plant genome sciences are essential to understanding how plants function and how to develop desirable plant characteristics. For example, plant genomic science can contribute to the development of plants that are drought-resistant, those that require less fertilizer, and those that are optimized for conversion to fuels such as ethanol and biodiesel. The National Plant Genome Initiative (NPGI) is a unique, cross-agency funding enterprise that has been funding and coordinating plant genome research successfully for nine years. Research breakthroughs from NPGI and the National Science Foundation (NSF) Arabidopsis 2010 Project, such as how the plant immune system controls pathogen defense, demonstrate that the plant genome science community is vibrant and capable of driving technological advancement. This book from the National Research Council concludes that these programs should continue so that applied programs on agriculture, bioenergy, and others will always be built on a strong foundation of fundamental plant biology research.

Download or read book Genetics and Genomics of Brachypodium written by John P. Vogel and published by Springer. This book was released on 2016-02-17 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grasses dominate many natural ecosystems and produce the bulk calories consumed by humans either directly in the form of grains or indirectly through forage/grain fed animals. In addition, grasses grown as biomass crops are poised to become a significant source of renewable energy. Despite their economic and environmental importance, research into the unique aspects of grass biology has been hampered by the lack of a truly tractable experimental model system. Over that past decade, the small, annual grass Brachypodium distachyon has emerged as a viable model system for the grasses. This book describes the development of extensive experimental resources (e.g. whole genome sequence, efficient transformation methods, insertional mutant collections, large germplasm collections, recombinant inbred lines, resequenced genomes) that have led many laboratories around the world to adopt B. distachyon as a model system. The use of B. distachyon to address a wide range of biological topics (e.g. disease resistance, cell wall composition, abiotic stress tolerance, root growth and development, floral development, natural diversity) is also discussed.
