In grain sorghum resistance to Colletotrichum Sweet sorghum thesis determined mostly by single genes and there is assumed to be a gene-for-gene relationship with the pathogen.
We surveyed eight fields in eastern Pennsylvania for the presence of C. The only work that remains is to prepare and submit a sample to a recognized herbarium to serve as the holotype for the species.
Dried stalks are used for cooking fuel, and dye can be extracted from the plant to color leather 3. The goal of this project is to evaluate the abilities of the native strains to colonize the non-host species and cause disease in immediate and surrounding areas.
Plant-defense against pathogens and pests through phytoalexins. Global warming and greenhouse gas GHG emissions are serious issues of our time. In addition we will include several null lines for y1 to better understand the role of 3-deoxyanthocyanidins in disease resistance under field conditions.
The main objectives of the center are to 1 improve the yield potential, production efficiency, and food, feed and bioenergy value of sorghum, through plant breeding and genetics; 2 develop new uses for sorghum in food and non-food applications, emphasizing the grain's Sweet sorghum thesis characteristics, such as the absence of gluten and a low glycemic index; 3 identify more efficient production strategies that will enhance water and nutrient use, particularly N, and provide new options for the control of weeds and pests, to increase sorghum yield and profits; 4 expand research on sorghum as a bioenergy crop uniquely adapted to drier regions of the US; and 5 provide market and policy analysis and develop educational programs for different sorghum-based products and production systems to increase profitability of all segments of the U.
There was a range of reactions among the lines, from highly susceptible to all isolates e. We have also obtained 30 forage sorghum lines both resistant and susceptible to anthracnose leaf blight. We carried out disease trials in using sorghum accessions that produced 3-Das at varying concentrations.
White sorghum is preferred for making tortillas. The focus of the center is on genetic improvement, production systems to enhance water and nutrient use, innovative strategies for weed control, utilization of sorghum in human food products, animal feed, and as a bioenergy and industrial feedstock, plus marketing, and policy analysis in support of the US sorghum industry.
The products generated from this research will significantly influence sorghum production and market opportunities at regional, national and international levels. Two more fields where sorghum was grown in the previous season will be surveyed again in a similar manner.
The disease was evaluated using a scale developed for anthracnose stalk rot in maize. In addition to evaluating these lines for resistance to anthracnose leaf blight, we will also quantify the phenolic, flavonoid and 3-deoxyanthocyanidins in the leaf tissue to better understand the role of these compounds in disease development.
We analyzed isolates using RAPD to separate haplotypes.
Fungi belonging to the genus Colletotrichum cause anthracnose on both sorghum and maize. There were haplotypes out of isolates from SS that were analyzed. Fungal strains collected from PA are being fingerprinted and genotyped PCR based to confirm their identity.
As such, many groups around the world are pursuing research initiatives around sorghum specifically Sorghum bicolor: These methods provided critical genetic information for future breeding programs.
Sweet sorghum has a high sugar content in its stalk, which can be turned into ethanol. Crutzen published findings that the release of nitrous oxide N2O emissions in the production of biofuels means that overall they contribute more to global warming than the fossil fuels they replace. And, although breeding has resulted in better nutritional value of sorghum and better flavor, earlier sorghums had higher tannin levels, which caused offensive flavor and was advantageously used as a deterrent to birds.
Conference Papers and Presentations Status: It has wax on its leaves and stems to reduce moisture loss, as well as narrow leaves and the ability to fold the leaves in on themselves — all strategies to conserve moisture in both heat and drought stress.
Studies wat in parallel uitgevoer was, het gefokus op die seleksie van soetsorghum kultivars en optimering van die kondisies vir stoom behandeling en die bepaling van die ensiempreparaat vir hidroliese. Therefore not much is known about how it will perform under increased anthracnose disease pressures, once it becomes more widely cultivated.
Biofuels made from waste biomass or from biomass grown on abandoned agricultural lands incur little to no carbon debt.
Interest in sorghum is definitely picking up, he added. However, these same isolates are quite aggressive on johnsongrass. Production of first generation bioethanol from food crops raised concerns over food supplies being channelled for biofuel production leading to possible increases in food prices.
The biofuel production process used for this study differed from other LCAs in that, in parallel to stalk juice extraction and fermentation, residual bagasse and vinasse was pyrolyzed and upgraded to a diesel equivalent as opposed to being fermented or combusted for a source of heat or electricity production.
When the seedlings are days old they will be inoculated with a suspension of C. Progress on the proposed objectives of this project is summarized below: Nothing Reported What do you plan to do during the next reporting period to accomplish the goals?
Katia is beginning her third year of her graduate program and has been making excellent progress. The pathogenicity of four Colletotrichum isolates from cultivated sorghum and from johnsongrass was compared on the susceptible sweet sorghum inbred Sugar Drip in the field.
Nothing Reported What opportunities for training and professional development has the project provided? Biochemical tests of 3-DAs produced in response to infection with C. Several sorghum germplasm collections, accessions and hybrids were evaluated for traits associated with drought tolerance, heat tolerance, cold tolerance, disease resistance, grain quality, utilization potential including bioenergy and yield potential.Sweet sorghum is a relatively new crop in China, and its sales network has not yet been developed; therefore, there is a large difference in the contracted price of the fresh stalks among regions, distinguishing sweet sorghum from the market price of major crops.
