Beet necrotic yellow vein virus 42 kDa triple gene block protein binds nucleic acid in vitro.
The triple gene block (TGB) of beet necrotic yellow vein virus RNA 2 is required for cell-to-cell movement of the virus RNA. The protein P42 encoded by the 5'-proximal gene of the TGB has consensus sequence motifs characteristic of an ATP/GTP-dependent helicase. P42 was over-expressed in Escherichia coli and shown to bind both single- and double-stranded RNA and DNA by Northwestern blotting. Si...
متن کاملInteractions Between Beet necrotic yellow vein virus and Beet soilborne mosaic virus in Sugar Beet
Beet necrotic yellow vein virus (BNYVV) and Beet soilborne mosaic virus (BSBMV) are members of the genus Benyvirus (9). Both viruses infect members of the family Chenopodiaceae, most notably sugar beet (Beta vulgaris L.), and are transmitted by the plasmodiophorid, Polymyxa betae (1,2). BNYVV infection causes rhizomania disease in sugar beet (4,21); however, BSBMV infection does not (28). BSBMV...
متن کاملGenetic Investigation of Resistance to Beet Necrotic Yellow Vein Virus
Management of rhizomania includes planting in cool soils, proper irrigation and soil fumigation with methyl bromide. However, breeding for resistance to BNYW is the most critical aspect of rhizomania control In this study, the inheritance of resistance to beet necrotic yellow vein virus (BNYW) in B. vulgaris subsp. maritima. wild beet (WB) accession WB42 was investigated. Crosses between resist...

Name: Beet necrotic yellow vein furovirus Taxonomic position: Viruses: Furovirus Common names: BNYVV (acronym) Rhizomania (English) Rhizomanie (French) Rizomanía (Spanish) Notes on taxonomy and nomenclature: Beet soil-borne furovirus (BSBV) has been shown to have the same host range and vector as BNYVV, and to cause similar symptoms (Henry et al., 1986; Lesemann et al., 1989). BSBV was classifi...
متن کاملMolecular Biology of the Beet necrotic yellow vein virus
Beet necrotic yellow vein virus is the etiological agent of one of the most devastating sugar beet viral diseases: rhizomania. This review describes the molecular biology of the rhizomania disease, the functions of the BNYVV encoded proteins, the consequences of their expression as well as the biology of the BNYVV vector, Polymyxa betae. Root proliferation is an important part of the well-known...
