This book was released on 2012-10-05 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of driving forces, including the soaring global crude oil prices and environmental concerns in both developed and developing nations has triggered a renewed interest in the recent years on the R&D of biofuel crops. In this regard, many countries across the globe are investing heavily in the bioenergy sector for R&D to increase their energy security and reduce their dependence on imported fossil fuels. Currently, most of the biofuel requirement is met by sugarcane in Brazil and corn in the United States, while biodiesel from rapeseed oil in Europe. Sweet sorghum has been identified as a unique biofuel feedstock in India since it is well adapted to Indian agro-climatic conditions and more importantly it does not jeopardize food security at the cost of fuel. Sweet sorghum [Sorghum bicolor (L.) Moench] is considered as a SMART new generation energy crop as it can accumulate sugars in its stalks similar to sugarcane, but without food¬¬-fuel trade-offs and can be cultivated in almost all temperate and tropical climatic conditions and has many other advantages. The grain can be harvested from the panicles at maturity. There is no single publication detailing the agronomic and biochemical traits of tropical sweet sorghum cultivars and hybrid parents. Hence, an attempt is made in this publication- “Characterization of improved sweet sorghum cultivars” to detail the complete description of cultivars. This book serves as a ready reference on the detailed characterization of different improved sweet sorghum genotypes following the PPVFRA guidelines for the researchers, entrepreneurs, farmers and other stakeholders to identify the available sweet sorghum cultivars and understand their yield potential in tropics.

Book Synopsis Agronomical, Physiological and Biochemical Approaches to Characterize Sweet Sorghum Genotypes for Biofuel Production by : Satheesh K. Subramanian
Download or read book Agronomical, Physiological and Biochemical Approaches to Characterize Sweet Sorghum Genotypes for Biofuel Production written by Satheesh K. Subramanian and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sweet sorghum (Sorghum bicolor L. Moench) is an important bioenergy crop. There is a wide array of genetic diversity in sweet sorghum germplasm collections. However, information on traits associated with sugar yield, optimum harvesting time for maximum sugar yield, effects of abiotic stresses on sugar yield is scarce. The objectives of the present study were: to identify traits that are associated with sugar yield, to determine the optimum harvesting time for maximum sugar yield and to understand the physiological responses of different sweet sorghum genotypes to drought and high temperature. In order to meet these objectives, five independent field and greenhouse studies were conducted. Field experiments were conducted using 280 sweet sorghum germplasm and were evaluated for 2 years. From this study, 30 genotypes representing high and low sugar yielders were selected for the subsequent experiment. We observed a significant variation in physiological, morphological and sugar yield traits associated with biofuel production. In the selection experiment, investigations on the morphological, physiological attributes helped to identify those characters which influence or limit sugar yield in the sweet sorghum. Another field study was conducted to optimize the harvesting time for obtaining highest sugar and juice yields in sweet sorghum. Sweet sorghum variety M81E was harvested at ten growth stages. Our results suggest that the optimum time for harvesting of sweet sorghum cultivar M81E is between milk and hard dough stages when highest sugar yield was observed. Studies on different levels of water stress were studied under greenhouse conditions. Four sweet sorghum genotypes (Awanlek, Smith, Tracy and Wray) were subjected to three water stress treatments (100% pot capacity (PC); 70% PC and 30% PC) for 20 days at early seed filling (Milk) stage. The results showed that genotypes differed significantly for all growth and yield, biochemical and physiological traits. Severe water stress significantly decreased juice and sugar yields by decreasing net photosynthetic rate, transpiration rate, stomatal conductance and sucrose content in the stem juice. Genotypes Tracy and Wray produced significantly highest brix, stem fresh weight, juice and sugar yield under both irrigated and water stress conditions. In another greenhouse study, we quantified the effects of drought, high temperature, and their combinations on growth, physiology and yield of sweet sorghum genotypes. The same four genotypes above were subjected to four treatments, T1 - control, T2 - drought stress, T3 - high temperature stress and T4 - combination of drought and high temperature for 16 days after anthesis. The result showed that significant difference was observed for growth and yield traits, physiological traits and non-reducing and total sugar content in juice for genotypes and treatments. Among the genotypes Tracy recorded higher juice and sugar yield. Among the various treatments, combination of drought and high temperature was found to be more deleterious in reducing most of the biofuel traits followed by drought and high temperature stress. The above studies gave significant findings with regards to the identification of superior sweet sorghum germplasm, their tolerance capacity to different abiotic stresses, which allows better selection for the use of bioenergy production.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent initiatives for biofuel production have increased research and development of sweet sorghum. Currently, the initial major limitation to integrating sweet sorghum into existing production systems is the lack of sweet sorghum hybrids adapted to industrial production systems. Hybrid development is now underway, and the application of genetic markers can be used to define the genetic basis of sugar yield and its components, as well as reduce the time required to deliver new sweet sorghum hybrids to market. The purpose of this research was to further characterize the genetic components that influence sweet sorghum productivity, agronomics, and composition. Specifically, a grain x sweet sorghum recombinant inbred line (RIL) population developed for quantitative trait locus (QTL) analysis related to sugar production was evaluated for 24 phenotypic traits including brix, percent moisture, and biomass yield across four environments. The 185 F4 RILs were derived from the parents 'BTx3197' and 'Rio', which are pithy stalk grain and juicy stalk sweet sorghums respectively. Following screening, two genetic maps were constructed with 372 and 381 single nucleotide polymorphisms (SNPs) evaluated using an Illumina GoldenGate assay. Analysis of the data in QTL Cartographer revealed a major and previously reported QTL for soluble solids on chromosome 3, but in contrast to previous studies, this QTL co-localized with other QTLs that have a negative influence on biomass and seed production. Therefore, selection for this QTL may not be advantageous. Because only a few QTLs for percent moisture were found, the results indicated that the pithy stalk phenotype does not have a major effect on percent moisture as measured in this study. Thus, breeding for high or low moisture content will be more challenging than previously expected. The absence of dominance effects indicated that brix must be high in both parents to produce high brix in the hybrid.

Download or read book Sorghum Molecular Breeding written by R. Madhusudhana and published by Springer. This book was released on 2015-08-20 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an up-to-date overview of international research work on sorghum. Its comprehensive coverage of our current understanding of transgenic development in sorghum and the strategies that are being applied in molecular breeding make this book unique. Important areas such as genetic diversity, QTL mapping, heterosis prediction, genomic and bioinformatics resources, post-genome sequencing developments, molecular markers development using bioinformatics tools, genetic transformation and transgenic research are also addressed. The availability of the genome sequence along with other recent developments in sequencing and genotyping technologies has resulted in considerable advances in the area of sorghum genomics. These in turn have led to the generation of a large number of DNA-based markers and resulted in the identification and fine mapping of QTL associated with grain yield, its component traits, biotic and abiotic stress tolerance as well as grain quality traits in sorghum. Though a large volume of information has accumulated over the years, especially following the sequencing of the sorghum genome, until now it was not available in a single reference resource. This book fills that gap by documenting advances in the genomics and transgenic research in sorghum and presenting critical reviews and future prospects. “Sorghum Molecular Breeding” is an essential guide for students, researchers and managers who are involved in the area of molecular breeding and transgenic research in sorghum and plant biologists in general.

Download or read book Genetic Dissection of Bioenerrgy Traits in Sorghum written by and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Specific Objectives: 1. To identify the gene(s) underlying a major QTL for stem sugar concentration located on chromosome 3. 2. To identify QTL for stem juice volume and stalk sugar concentration and to identify the underlying genes. 3. To classify 60 novel sorghum bmr mutants from the USDA TILLING population in allelic groups based on cell wall chemistry and allelism tests. 4. To select representative bmr mutants from each allelic group and selected NIR spectral mutants for their potential value as feedstock for ethanol production. 5. To clone and characterize those Bmr genes that represent loci other than Bmr12 and Bmr6 using a mapping and a candidate gene approach. Objective 1 The experiments for this objective are largely complete and the data have been analyzed. Data interpretation and follow-up experiments are still in progress. A manuscript is in preparation (Vermerris et al.; see publication list for full details). The main results are: 1) 16 cDNA libraries were prepared and sequenced at Cornell University. The libraries represent internode tissue and flag leaf tissue at booting, internode tissue and peduncle at soft-dough stage, from two plants per sampling time with the Rio allele for the QTL on chromosome 3, and two plants with the BTx623 allele on chromosome 3 (4 tissues x 2 genotypes x 2 replicates) 2) 480 million 86-nucleotide reads were generated from four lanes of Illuminia HiSeqII 3) 74% of the reads could be mapped to the sorghum transcriptome, indicative of good sequence quality 4) Of the 216 genes within the QTL, 17 genes were differentially expressed among plants with and without the Rio QTL. None of these 17 genes had obvious roles in sucrose metabolism 5) Clustering algorithms identified a group of 721 co-expressed genes. One of these genes is a sucrose synthase gene. This cluster also contains 10 genes from the QTL. 6) Among these co-expressed genes are regulatory genes for which knock-out lines in Arabidopsis have been obtained. Analysis of these lines is in progress. Objective 2 The experiments from this objective have been completed and the data were published in the journal Crop Science by Felderhoff et al. (2012). A second publication by Felderhoff et al. is in progress (see publication list for full details). The experiments were based on a mapping population derived from the sweet sorghum 'Rio' and the dry-stalk grain sorghum BTx3197. The main findings were: 1) The apparent juiciness of the sorghum stalk, based on the appearance of a cut stem surface (moist vs. pithy), is not representative of the moisture content of the stalk. This was surprising, as pithy stalks have been associated with low moisture content. This means that in order to assess 'juiciness', a different evaluation needs to be used, for example by removing juice with a roller press or by measuring the difference in mass between a fresh and dried stalk segment. 2) A total of five QTLs associated with juice volume (corrected for height) or moisture content were identified, but not all QTLs were detected in all environments, providing evidence for genotype x environment interactions. This finding complicates breeding for juice volume using marker-assisted selection. 3) The QTL for sugar concentration identified on chromosome 3, and the subject of Objective 1, was confirmed in this mapping population, but unlike in previous studies (Murray et al., 2008), the presence of this QTL was associated with negative impacts on agronomic performance (fresh and dry biomass yield, juice yield). Consequently, introgression of the Brix QTL from Rio as part of a commercial breeding program will require monitoring of the precise impacts of this QTL on agronomic performance. 4) The absence of dominance effects for the Brix trait (= sugar concentration) indicated that Brix must be high in both parents to produce high Brix in hybrids. This means an extra constraint on the development of hybrid parents. With the results from Objective 1, the selection ...

Available in PDF, EPUB and Kindle. Book excerpt: Nonrenewable energy resources deplete with the passage of time due to rapid increase in industrialization and population. Hence, countries worldwide are investing dearly in substitute energy resources like biofuel from miscellaneous set of feedstocks. Among the energy crops, sorghum serves as a model crop due to its drought tolerance, small genome size (730 Mb), high biomass, dry matter contents, quick growth, wide adaptability to diverse climatic and soil conditions and C4 photosynthesis. Sweet sorghum with high sugar content in stalk is an efficient feedstock for advanced biofuels and other bio-based products from sugars. However, high biomass sorghum has the utility as a feedstock for cellulosic biofuels. The enhanced yield of monomeric carbohydrates is a key to cheap and efficient biofuel production. The efficiency of lignocellulosic biofuels is compromised by recalcitrance to cell wall digestion, a trait that cannot be efficiently improved by traditional breeding. Therefore, scientists are looking for solutions to such problems in biomass crop genomes. Sorghum genome has been completely sequenced and hence this crop qualifies for functional genomics analysis by fast forward genetic approaches. This chapter documents the latest efforts on advancement of sorghum for biomass potential at morphological and molecular level by exploiting genomics approaches.
Book Synopsis Genetic Analysis of the 'dry' Trait, Stem Architecture and Plant Water Content Components in Sorghum by : Huizhe Jin

This book was released on 2016 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: With increasing energy demand and diminishing petroleum reserves, energy sources derived from renewable plant-based biomass are an attractive substitute for fossil fuels. Being the fifth most widely grown cereal crop in the world, sorghum is among one of the most attractive bioenergy feedstocks currently under active study. In this thesis, we provide a valuable addition to the genetic resources of sorghum by describing a recombinant inbred line (RIL) population of 161 F5 genotypes for the widest euploid cross that can be made in eusorghums, of annual S. bicolor x perennial S. propinquum. It offers advantages over early-generation populations of this cross that will shed new light on genetic, environmental, and physiological / biochemical factors that regulate plant growth and development. A combination of linkage and association genetic approaches using a S. bicolor x S. propinquum F2 population, a S. bicolor BTx623 x IS3620c RIL population, and a S. bicolor diversity panel of 354 accessions characterized at 265,487 SNPs allows us to: tentatively identity and characterize the D gene for the 0́dry' trait; and determine genomic regions corresponding to 3 stem diameter traits and 2 water content traits. We also revealed the evolutionary path of the D gene, as having evolved under balancing selection during a recent tandem expansion of the BGLU gene family in sorghum after its divergence from maize. Co-localizations of stem diameter and water content traits with a number of other bioenergy traits, including plant height, flowering time, branching, stem volume and the 0́8dry' trait, were also observed, suggesting that their inheritance may be functionally (pleiotropy) or physically (linkage disequilibrium) linked. Increasing knowledge of the genetic control of these bioenergy traits in sorghum, and in identification of corresponding genes and their functions, may lead to tools and strategies for either enhancing or suppressing these traits, supporting advances toward greater use of plant-based biomass in biofuel production.

Available in PDF, EPUB and Kindle. Book excerpt: Climate change has been anticipated to affect agriculture, with most the profound effect in regions where low input agriculture is being practiced. Understanding of how plants evolved in adaptation to diverse climatic conditions in the presence of local stressors (biotic and abiotic) can be beneficial for improved crop adaptation and yield to ensure food security. Great genetic diversity exists for agroclimatic adaptation in sorghum (Sorghum bicolor L. Moench) but much of it has not been characterized. Thus, limiting its utilization in crop improvement. The application of next-generation sequencing has opened the plant genome for analysis to identify patterns of genome-wide nucleotide variations underlying agroclimatic adaptation. To understand the genetic basis of adaptive traits in sorghum, the genetic architecture of sorghum inflorescence traits was characterized in the first study. Phenotypic data were obtained from multi-environment experiments and used to perform joint linkage and genome-wide association mapping. Mapping results identified previously mapped and novel genetic loci underlying inflorescence morphology in sorghum. Inflorescence traits were found to be under the control of a few large and many moderate and minor effect loci. To demonstrate how our understanding of the genetic basis of adaptive traits can facilitate genomic enabled breeding, genomic prediction analysis was performed with results showing high prediction accuracies for inflorescence traits. In the second study, the sorghum-nested association mapping (NAM) population was used to characterize the genetic architecture of leaf erectness, leaf width, and stem diameter. About 2200 recombinant inbred lines were phenotyped in multiple environments. The obtained phenotypic data was used to perform joint linkage mapping using ~93,000 markers. The proportion of phenotypic variation explained by QTL and their allele frequencies were estimated. Common and moderate effects QTL were found to underlie marker-trait associations. Furthermore, identified QTL co-localized with genes involved in both vegetative and inflorescence development. Our results provide insights into the genetic basis of leaf erectness and stem diameter in sorghum. The identified QTL will also facilitate the development of genomic-enable breeding tools for crop improvement and molecular characterization of the underlying genes Finally, in a third study, 607 Nigerian accessions were genotyped and the resulting genomic data [about 190,000 single nucleotide polymorphisms (SNPs)] was used for downstream analysis. Genome-wide scans of selection and genome-wide association studies (GWAS) were performed and alongside estimates of levels of genetic differentiation and genetic diversity. Results showed that phenotypic variation in the diverse germplasm had been shaped by local adaptation across climatic gradient and can provide plant genetic resources for crop improvement.
