Evidence that the 75K readthrough protein of beet necrotic yellow vein virus RNA-2 is essential for transmission by the fungus Polymyxa betae.
Two mutant strains of beet necrotic yellow vein virus (BNYVV) containing deletion mutants of RNA-2 were produced during serial passage in mechanically inoculated Tetragonia expansa leaves. The mutant strains were referred to as S-0a (RNA-1 + 2a) and G-0b (RNA-1 + 2b). RNA-2a and RNA-2b were about 4.3 kb and 4.2 kb in length, respectively, whereas normal sized RNA-2 was about 4.8 kb in length. I...

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...
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 کاملNucleotide Sequence of Beet Necrotic Yellow Vein Virus RNA-1
The complete nucleotide sequence of beet necrotic yellow vein virus RNA-1 is presented. The R N A molecule is 6746 nucleotides long excluding the poly(A) tail and has one long open reading f lame encoding a polypeptide of M r 237 389. The 3' terminal 60 residues of BNYVV RNA-1 display extensive sequence homology with the corresponding portions of BNYVV RNA-2, -3 and -4. Addi t ional 3' terminal...
