2011 Annual Report

1a. Objectives (from AD-416)
Utilization and development of bioinformatic and genomic tools/information to support structural analysis of plant and animal genomes. This includes the generation of DNA sequences and subsequent analysis. Development and implementation of DNA markers for development of superior cultivars (e.g., superior yield, improved quality, or resistance to the biotic or abiotic factors) or germplasm/population/species characterization. Both marker data and DNA sequences will be used for genome structure analysis.

1b. Approach (from AD-416)
The Genomics and Bioinformatics Research Unit conducts research in the area of genomics and bioinformatics for an array of species and topics. It also acts as a fully integrated component of the Mid South Area by providing genomics research support for an array of technologies and research projects. The support includes, but is not limited to high throughput DNA sequencing, gene expression analysis, bioinformatics, DNA marker development, BAC fingerprinting and high throughput genotyping with DNA marker. The centralization of these operations assures that all research projects in the MSA that could benefit from these genomic tools have access to the technology, that there is no unnecessary duplication of equipment within the Area, and there is maximum utilization and conservation of funding.

3. Progress Report
As a service in-house research project, progress is measured by the service provided. For the reported time period these ARS locations had significant amount of DNA sequencing (D), genotyping (G), bioinformatics (B) and/or DNA marker development (M) processed through the Laboratory: Animal Waste Management Research Unit, Service: D Aquatic Animal Health Research Unit, Service: D Biological Control of Pests Research Unit, Service: D Catfish Genetics Research Unit, Service: D,B,G, Commodity Utilization Research Unit, Service: D Coastal Plains Soil, Water, and Plant Research Center, Service: D Corn Host Plant Resistance Research, Service: D,B Cotton Fiber Bioscience Research Unit. Service: D, G Crop Genetics Research Unit, Service: D, G, B Crop Germplasm Research, Service: G Dale Bumpers National Rice Research Center: D Food Processing and Sensory Quality Research Unit, Service: D Formosan Subterranean Termite Research Unit: G Genetics and Precision Agriculture Research, Service: D Natural Products Utilization Research Unit, Service: D, Southern Insect Management Research Unit, Service: D,B Soybean Genomics and Improvement, Service: D, B Subtropical Horticulture Research Station, Service: B,G,M Sugarcane Field Station, Service: D,G,M Sugarcane Research Unit, Service: G Sunflower Research Unit, Service: D Tropical Agriculture Research Station, Service: B,D,G,M Tropical Plant Genetic Resources and Disease Research Unit: G DNA marker development, validation, and utilization, has become an important output component of the unit. In the past year a rice breeders Single Nucleotide Polymorphism (SNP) chip was developed in an international effort in which Genomics and Bioinformatics Research Unit (GBRU) participated by providing resequencing data and validation of a chip designed for U.S.A. breeders in cooperation with the Dale Bumpers National Rice Research Center and Cornell University. DNA markers can be used for many purposes and three major ones are for identification, classification of relationship or for associating a DNA marker with a physical trait. Three large studies are in progress that are near completion. One involves over 2,000 cotton accessions and almost 100 DNA markers. This work is joint effort with the Cotton Fiber Bioscience Research Unit and Crop Germplasm Research Unit and will represent the largest publically effort to characterize cotton germplasm. Another study involves the characterization of the U.S.A. germplasm collection of tropical bamboos and related species. This is done in conjunction with the Tropical Agriculture Research Station. A different study is examining the relationship of almost 400 accessions of breadfruit and jackfruit of which approximately half are in germplasm collections in the U.S.A. This is done in conjunction with the Tropical Agriculture Research Station, Tropical Plant Genetic Resources and Disease Research Unit, Northwestern University, the Chicago Botanic Garden and the National Tropical Botanical Garden.
