The coat protein of Beet curly top virus
is essential for infectivity.
The sugar beet curly top virus
could meet its match in new sugar beet varieties derived from KDH13, a germplasm breeding line developed by Agricultural Research Service (ARS) researchers for resistance to the disease-causing pathogen.
Plants expressing tomato golden mosaic virus AL2 or beet curly top virus
L2 transgenes show enhanced susceptibility to infection by DNA and RNA viruses.
sugar beet producers also battle beet curly top virus
. The scientists developed a set of genetic markers that plant breeders could use in developing curly top-resistant sugar beet varieties.
C931 is moderately resistant to Beet curly top virus
, virus yellows (caused by Beet chlorosis virus and Beet yellows virus), powdery mildew [caused by Erysiphe polygoni DC.
The beet curly top virus
was the first viral disease that Esau undertook to study.
Crimson owes its seed features and disease resistance to Cardinal, and specifically that cultivar's I and Bct genes, which confer protection against the bean common mosaic virus and beet curly top virus
FC720 and FC722 have good resistance to root-rotting strains (AG-2-2) of Rhizoctonia solani Kuhn and good to moderate resistance to Cercospora leaf spot (caused by Cercospora beticola Sacc.), but are not resistant to the Beet curly top virus
It is moderately resistant to Beet curly top virus
(BCTV) and should have genetic variability for high levels of resistance.
It has been selected for resistance to Cercospora leaf spot caused by Cercospora beticola Sacc., and has moderate resistance to black root (caused by Aphanomyces cochlioides Drechsl.) and the Beet curly top virus
solani and Beet curly top virus
(BCTV)] and nonstressed environments.
It is intermediate for reaction to Beet curly top virus
, similar to C78/3 (Lewellen, 2004a).
