Abstract: Switchgrass is an increasingly important biofuel crop, but knowledge of switchgrass fungal pathogens is not extensive. The purpose of this research was to identify the fungal pathogens that decrease crop yield of switchgrass grown in Tennessee and to investigate a potential sustainable disease management strategy from a value-added by-product of the switchgrass biofuel conversion process. The specific objectives were 1) to identify and characterize prevalent fungal pathogens of switchgrass in Tennessee, 2) assess switchgrass seed produced in the United States for seedborne fungal pathogens, and 3) evaluate switchgrass extractives for antimicrobial activity against plant pathogens.

Abstract: The invention provides methods for identifying compounds and compositions useful in the regulation of weight, the treatment of obesity, diabetes and other insulin resistance-related disorders hypertension, cardiovascular disease and the like. The methods comprise the use of adipocytes and predipocytes in assays and screens for compounds or compositions of interest. The present invention recognizes the presence of the sulfonylurea receptor in adipocytes and its utility in identifying compounds and in treating obesity and other insulin resistance-related disorders. In addition to assaying for agonists and antagonists of the sulfonylurea receptor, the methods of the invention also provide for identifying novel calcium channels or other calcium regulatory channels that are selectively expressed in human adipocytes as compared to human preadipocytes and for screening adipocytes for compounds that selectively antagonize calcium.

Abstract: The invention provides methods for determining the ability of compounds to regulate lipogenesis and lipolysis by acting as a sulfonylurea-1 (SUR 1) potassium channel activator, an adipocyte potassium channel activator, an SUR 1 antagonist, and an adipocyte specific SUR 1 antagonist. The present invention recognizes the presence of the sulfonylurea receptor in adipocytes and its utility in identifying compounds and in regulating lipogenesis and lipolysis.
