Characterization of CbCyp51 from field isolates of Cercospora beticola.
The hemibiotrophic fungus Cercospora beticola causes leaf spot of sugar beet. Leaf spot control measures include the application of sterol demethylation inhibitor (DMI) fungicides. However, reduced sensitivity to DMIs has been reported recently in the Red River Valley sugar beet-growing region of North Dakota and Minnesota. Here, we report the cloning and molecular characterization of CbCyp51, ...
متن کاملMorphological and Genetic Diversity of Cercospora beticola Isolates
The fungus Cercospora beticola Sacc. is the one of the most important pathogens on the sugar beet. This plant pathogen causes cercospora leaf spot disease which is a serious economic problem for growers of this crop all over the world. Traditionally, the identification of C. beticola is based mainly on conidial characters and host association, but today molecular characterization is necessary f...
متن کاملreaction of sugar beet cultivars to cercospora beticola isolates
twenty four isolates of cercospora beticola were collected from khuzestan, ardebil, golestan and mazandaran provinces and purified, and one isolate was used to represent each province. after optimization of spore production on different media, pathogenic variability of selected isolates on five sugar beet varieties with different levels of resistance was studied under green house condition. fou...
متن کاملPcr-based Detection of Strobilurin Resistance in Cercospora Beticola*
Cercospora leaf spot (CLS), caused by the fungus Cercospora beticola (Sacc.), is the most destructive foliar pathogen of sugarbeet worldwide. Control measures include the use of resistant varieties and crop rotation, but timely fungicide applications are essential for CLS management. Resistance to sterol demethylation inhibitor (DMI) fungicides (FRAC group 3) has been increasing in C. beticola ...
متن کاملCarbon-utilization patterns in the photoresponsive fungus Cercospora beticola.
The leaf-spot disease of sugar beet caused by Cercospora beticola is of considerable economic importance in these countries where the conditions of high light-intensity (Calpouzos & Stallknecht, 1967) and relative humidity (Pool Rr McKay, 1916) favour spore germination and the establishment of infection. High light-intensity greatly increases carbohydrate exudation from leaves (Tukey et al., 19...
