histopathological 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...
متن کاملNon-invasive Presymptomatic Detection of Cercospora beticola Infection and Identification of Early Metabolic Responses in Sugar Beet
Cercospora beticola is an economically significant fungal pathogen of sugar beet, and is the causative pathogen of Cercospora leaf spot. Selected host genotypes with contrasting degree of susceptibility to the disease have been exploited to characterize the patterns of metabolite responses to fungal infection, and to devise a pre-symptomatic, non-invasive method of detecting the presence of the...
متن کاملMagnetic resonance imaging of sugar beet taproots in soil reveals growth reduction and morphological changes during foliar Cercospora beticola infestation
Cercospora leaf spot (CLS) infection can cause severe yield loss in sugar beet. Introduction of Cercospora-resistant varieties in breeding programmes is important for plant protection to reduce both fungicide applications and the risk of the development of fungal resistance. However, in vivo monitoring of the sugar-containing taproots at early stages of foliar symptoms and the characterization ...
