Deletion of MAT1-1-1 and MAT1-2-1 genes had a significant negative effect on aggressiveness to wheat, and on mycotoxin production in planta and in vitro, while deletion of the complete MAT1 locus has no effect on disease development nor on mycotoxin production.

About the Federal Register New types of fingerprinting markers were developed and used to characterize a population of F. graminearum causing head blight on soft red winter wheat in Kentucky. Mycotoxins can be produced in grain during storage or processing, but are most frequently associated with fungal infection that occurs before harvest.

Citation: resources needed (i.e., project personnel, IT resources)New method implementation is not always a simple process. We learned that most of the isolates belonged to the dominant chemotype, but that genetically they showed signs of being an isolated divergent population, suggesting there is not a lot of mixing of isolates from outside of Kentucky.

Characterization of Fusarium strains recovered from wheat with symptoms of head blight in Kentucky. The expiration dates for existing certificates of conformance would not be affected. AMS establishes the test kit performance criteria and periodically updates them to improve testing accuracy and to meet the official mycotoxin testing program's operational needs. An essential part of ensuring the quality of official mycotoxin testing is the AMS test kit evaluation program, through which test kits are evaluated and certified for conformance to specific criteria.

Symphony agar allows the enumeration of yeasts and molds in all human and animal food products regardless of their water activity. To evaluate test kit accuracy, AMS requires analyses of reference materials to be performed at different concentrations across the range of conformance. As a result, AMS proposes to expand the current minimum range of conformance from 0.50-30 ppm to 0.50-100 ppm so that it includes this highest guidance level. The test kit must conform to the AMS accuracy requirements throughout this range. on 0 S. maydis causes Diplodia ear rot (DER) and Diplodia stalk rot (DSR) of maize, and it produces the mycotoxin Diplodiotoxin, which causes toxicosis in cattle and other animals that feed on the grain. Each mycotoxin has one or two primary grains, which must be included in the scope of the test kit. AMS is seeking comments on the impact of making these changes.

The studies also showed comparable recovery of osmophilic mold and yeast strains to NQA-00.4420 in high sugar products, however equivalency to this method has not yet been fully evaluated. AMS is interested in comments on whether the maximum conformance limit should also be changed from 100 ppb to 20 ppb, resulting in a narrower minimum range of conformance (i.e., 1.0-20 ppb). Stakeholders need cost-effective methods to predict, monitor, and minimize mycotoxin production in the field, and to detoxify mycotoxins and prevent further deterioration in contaminated grain.
