Acid beverage floc (ABF), a flocculated turbid material that can form in sugar-sweetened, acidified, carbonated beverages after several days standing, is a customer problem to bever­ age bottlers and their suppliers of sugar. ABF from beet sugar has been reported to be caused by a saponin from the beet plant, and recent work has shown the presence of several sa­ ponins in sugarbeet. ABF from ca...

Angiogenesis and its regulation is a crucial physiological response to chronic tissue ischemia causing increased microvessel growth along with collateral arteriolar remodeling to restore blood flow to deprived tissues.1 Vascular occlusion, as seen in coronary and peripheral artery disease, often progresses to chronic tissue ischemia without effective vascular remodeling responses.2 Thus, therap...

Gibberella zeae is one of the most devastating pathogens of barley and wheat in the United States. The fungus also infects noncereal crops, such as potatoes and sugar beets, and the genetic relationships among barley, wheat, potato, and sugar beet isolates indicate high levels of similarity. However, little is known about the toxigenic potential of G. zeae isolates from potatoes and sugar beets...

Rhizoctonia solani causes crown rot of sugar beets, a severe disease that has destroyed up to 60% of the plants in a test field in western Nebraska. Laetisaria arvalis, a natural hyperparasite of Rhizoctonia spp., was isolated from fields in western Nebraska. To test for the potential for biological control of R. solani, in November 1980 (following harvest) we applied various combinations of a ...
