abstract polymyxa betae is an obligate parasite and has a worldwide distribution. this fungus is a soil-borne root endoparasite in some plant families such as portulaceae, chenopodiaceae and amaranthaceae. this fungus is the vector of many plant viruses such as beet necrotic yellow vein virus (bnyvv) which causes the disease known as rhizomania. bnyvv is the most economical important viral dise...

rhizomania is one of the most important sugar beet diseases in iran and some other parts of the world. in this study, the infection rate of the most important weeds of sugar beet fields under natural condition  to the causal agent of the bnyvv (beet necrotic yellow vein virus) disease  was investigated at fars agricultural research center , iran. roots were collected from the infected weeds and...

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...

The reform of the European Union's sugar regime caused potential decreasing beet prices. Therefore, the Speeding Up Sugar Yield (SUSY) project was initiated. At the start, a 3 × 15 target was formulated: in 2015 the national average sugar yield in the Netherlands equals 15 t/ha (60% of the sugar beet potential) and the total variable costs 15 euro/t sugar beet, aspiring a saving on total variab...

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...

The RNA3-encoded p25 protein of beet necrotic yellow vein virus (BNYVV) is responsible for the production of rhizomania symptoms of sugar beet roots (Beta vulgaris subsp. vulgaris). Here, it was found that the presence of the p25 protein is also associated with the resistance response in rub-inoculated leaves of sugar beet and wild beet (Beta vulgaris subsp. maritima) plants. The resistance phe...
