Multiplex reverse transcription-PCR for simultaneous detection of beet necrotic yellow vein virus, Beet soilborne virus, and Beet virus Q and their vector Polymyxa betae KESKIN on sugar beet.
Three soilborne viruses transmitted by Polymyxa betae KESKIN in sugar beet have been described: Beet necrotic yellow vein virus (BNYVV), the agent of rhizomania, Beet soilborne virus (BSBV), and Beet virus Q (BVQ). A multiplex reverse transcription-PCR technique was developed to simultaneously detect BNYVV, BSBV, and BVQ, together with their vector, P. betae. The detection threshold of the test...
متن کاملAnalysis of the resistance-breaking ability of different beet necrotic yellow vein virus isolates loaded into a single Polymyxa betae population in soil.
The genome of most Beet necrotic yellow vein virus (BNYVV) isolates is comprised of four RNAs. The ability of certain isolates to overcome Rz1-mediated resistance in sugar beet grown in the United States and Europe is associated with point mutations in the pathogenicity factor P25. When the virus is inoculated mechanically into sugar beet roots at high density, the ability depends on an alanine...

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 کاملEvidence 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...
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...
