Although most resistance genes (R-genes) deployed against virus infections have lasted more than 25 years, the effectiveness of Rz1 that confers partial resistance against Beet necrotic yellow vein virus (BNYVV) was compromised in approximately 10 years in MN/ND by the emergence of resistance breaking (RB) strains of BNYVV (5). Using reverse genetics, Koenig et al. (3) demonstrated that for Eur...

Background: Polymyxa betae is the vector of several soil-borne viruses of sugarbeet (Abe and Tamada 1986, Liu and Lewellen 2008, Wisler et al. 1994, Kaufmann et al. 1992), including Beet necrotic yellow vein virus (BNYVV), the cause of rhizomania (Tamada and Baba 1973). BNYVV is transmitted by zoospores of this fungus-related microorganism that swim in water films and infect feeder roots of sug...

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...

Abstract. Aim of the investigations is to study, summarize and analyze domestic foreign literature concerning interaction molecular genetics classical sugar beet breeding for improvement resistance biotic abiotic stresses. The problems are: 1) a current state molecular-genetic in literature; 2) study marker-oriented breeding; 3) estimate development prospects research Russian Federation. Method...
