Biology
Rice hoja blanca virus is a member of the genus Tenuivirus. The RHBV genome consists of four single stranded linear RNA species, and the total genome is estimated to be 17.6 kb The RNA 1 is 9.8 kb and encodes for an RNA dependent RNA polymerase on the negative strand. The RNA 2 is 3,620 nucleotides and encodes two proteins using the ambisense coding strategy. The RNA 3 consists of 2,299 nucleotides and encodes for two proteins using an ambisense coding strategy. The nucleoprotein gene (N) is encoded by the virus complementary strand of RNA 3. The RNA 4 consists of 1,991 nucleotides and encodes for two proteins using an ambisense coding strategy.
