Global genotype flow in Cercospora beticola populations confirmed through genotyping-by-sequencing
Genotyping-by-sequencing (GBS) was conducted on 333 Cercospora isolates collected from Beta vulgaris (sugar beet, table beet and swiss chard) in the USA and Europe. Cercospora beticola was confirmed as the species predominantly isolated from leaves with Cercospora leaf spot (CLS) symptoms. However, C. cf. flagellaris also was detected at a frequency of 3% in two table beet fields in New York. R...
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 کاملhistopathological study of resistance to cercospora beticola in sugar beet
infection process including spore germination, penetration and intercellular development of cercospora beticola in the mesophyll of immature and mature leaves of two resistant (fd0018 and hm1836) and a susceptible genotypes (236) of sugar beet were studied, in order to determine the relative importance of defense phenomena in pre and post-penetration stage of infection to the pathogen in sugar...
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 کاملFluctuations in number of Cercospora beticola conidia in relationship to environment and disease severity in sugar beet.
Cercospora leaf spot, caused by Cercospora beticola, is the most damaging foliar disease of sugar beet in Minnesota (MN) and North Dakota (ND). Research was conducted to characterize the temporal progression of aerial concentration of C. beticola conidia in association with the environment and disease severity in sugar beet. In 2003 and 2004, volumetric spore traps were placed within inoculated...
