The objective of this continuing project is to characterize isolates of Cercospora sojina, the causal agent of frogeye leaf spot on soybean, to race and to develop specific molecular markers to distinguish races of the pathogen. Greenhouse assays are underway to characterize 23 isolates of the fungus collected in Illinois using the race scheme recently proposed. DNA isolated from the fungal isolates and primers has been designed to amplify the Internal Transcribed Spacer Regions (ITS) of the rDNA. The amplified DNA fragments are being sequenced and analyzed to identify polymorphism amongst the isolates.
The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
