Book excerpt: The global increase in energy needs has driven significant attention to the production of bioenergy, which is the energy produced from biological materials. Moreover, this attention has been exacerbated by concerns related to the effects of climate change on energy security. The goal of this thesis was to dissect the genetic architecture of cell wall composition and digestibility in plant tissues relevant for the production of bioenergy, specifically, cellulosic ethanol from maize stover. The cost-effective production of cellulosic ethanol depends, to a large extent, on advancing knowledge in four main areas: (1) characterizing of endogenous variation to determine the appropriate germplasm source(s) needed for cellulosic ethanol production, (2) assessing the effects of cell wall composition and cell wall structure on the efficiency of enzymatic hydrolysis (digestibility), (3) characterizing maize genes that can be genetically transformed to enhance biomass yield and conversion efficiency, and (4) developing of rapid screening protocols to evaluate biomass conversion efficiency. This thesis involves the aforementioned four areas. First, a stalk-core sampling device and procedure were developed to allow high-throughput screening of thousands of maize stalk-core samples. Second, tropical and other non-temperate maize germplasm sources were characterized for cell wall composition and digestibility diversity. Third, the relationships among various cell wall composition and digestibility traits across two relevant biomass tissues, as well as their repeatabilities and heritabilities, were evaluated. Subsequently, the genetic architecture of quantitative variation in maize cell wall composition and digestibility was dissected in diverse maize populations, providing direction to potential breeding strategies expected to improve the utility of maize biomass for the production of biofuels. In summary, this thesis constitutes a substantial effort to establish research and breeding strategies to accelerate the development of renewable fuels from plant biomass.

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.

Book excerpt: Plant cell walls are complex, dynamic cellular structures essential for plant growth, development, physiology and adaptation. Plant Cell Walls provides an in depth and diverse view of the microanatomy, biosynthesis and molecular physiology of these cellular structures, both in the life of the plant and in their use for bioproducts and biofuels. Plant Cell Walls is a textbook for upper-level undergraduates and graduate students, as well as a professional-level reference book. Over 400 drawings, micrographs, and photographs provide visual insight into the latest research, as well as the uses of plant cell walls in everyday life, and their applications in biotechnology. Illustrated panels concisely review research methods and tools; a list of key terms is given at the end of each chapter; and extensive references organized by concept headings provide readers with guidance for entry into plant cell wall literature. Cell wall material is of considerable importance to the biofuel, food, timber, and pulp and paper industries as well as being a major focus of research in plant growth and sustainability that are of central interest in present day agriculture and biotechnology. The production and use of plants for biofuel and bioproducts in a time of need for responsible global carbon use requires a deep understanding of the fundamental biology of plants and their cell walls. Such an understanding will lead to improved plant processes and materials, and help provide a sustainable resource for meeting the future bioenergy and bioproduct needs of humankind.

Available in PDF, EPUB and Kindle. Book excerpt: Plant Polysaccharides, an exceptional new volume in Wiley-Blackwell’s successful Annual Plant Reviews series, covers the polysaccharides and proteins that form the fundamental architecture of the plant cell wall, and the genes that encode the cellular machinery that synthesizes them. The volume focuses on the evolution of the many families of genes whose products are required to make a particular kind of polysaccharide, bringing attention to the specific biochemical properties of the proteins to the level of kinds of sugar linkages they make. Beautifully illustrated in full colour throughout, this exceptional new volume provides cutting edge up-to-date information on such important topics as cell wall biology, composition and biosynthesis, glycosyltransferases, hydroxyproline-rich glycoproteins, enzymatic modification of plant cell wall polysaccharides, glycan engineering in transgenic plants, and polysaccharide nanobiotechnology. Drawing together some of the world’s leading experts in these areas, the editor, Peter Ulvskov, has provided a landmark volume that is essential reading for plant and crop scientists, biochemists, molecular biologists and geneticists. All libraries in universities and research establishments where plant sciences, agriculture, biological, biochemical and molecular sciences are studied and taught should have copies of this important volume.

Available in PDF, EPUB and Kindle. Book excerpt: In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.
