investigation on beet soilborne virus (bsbv) in northern khorasan province
Authors
abstract
abstract beet soilborne virus (bsbv) is a member species of the genus pomovirus with rigid rod particles and 3 positive single stranded rnas. the virus is transmitted by polymyxa betae and restricted to chenopodiaceae. a survey was conducted in 2005 for identification of bsbv in northern khorasan province. samples showing yellowing, elongated and upright petioles with narrow leaf lamina and hairy roots were collected from fields of shirvan, bojnord and esfarayen. detection of bsbv was based on tas-elisa test. our survey showed that different fields in shirvan and bojnord were infected with bsbv. also for detection of mixed infection with bnyvv, samples were tested by das-elisa as well. our investigation showed that some fields in shirvan and bojnord had mixed infection with both viruses. this is the first report of infection with bsbv in shirvan and bojnord located in northern khorasan province.

Interactions 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...

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...
