Rapid, small scale purification of rice hoja blanca and Echinochloa hoja blanca tenuivirus ribonucleoprotein.
Highly purified tenuivirus ribonucleoprotein was obtained from small amounts of leaf tissue by sedimenting the ribonucleoprotein particles from debris-free plant extract into a 30% sucrose cushion, in 1.5-mL microfuge tubes. Using this protocol, significant size differences were discovered in the double-stranded forms of the viral genomic RNAs of rice hoja blanca tenuivirus and a tenuivirus isolated from Echinochloa colonum, a common weed of rice cultivation.
