Interpretive Summary:

Technical Abstract: Sugar beet leaf spot disease caused by Cercospora beticola often has a significant impact on both sugar beet yield and quality in some areas of the United States including the Red River Valley and Michigan. Our lab had previously produced some transgenic sugar beets possessing novel pathogen-defense genes specifying antimicrobial proteins. This study was conducted to examine the ability of these new genotypes to inhibit the growth of Cercospora. However, axenic sugar beet leaflets evidently supply the fungal pathogen with required growth factors not found in chemically defined media and thus are an excellent substrate for the in vitro growth of Cercospora. These growth factors are being determined.
