| identification and sequence analysis of potato yellow vein virus capsid protein minor gene. | potato yellow vein virus (pyvv) is a whitefly-transmitted (trialeurodes vaporariorum) closterovirus (wtc) with an as yet unidentified genome composition. pyvv dsrna preparations consist of three high molecular weight dsrna species (dsrnas 1, 2 and 3) 8.0, 5.5 and 4.0 kbp in size respectively, as well as two low molecular weight dsrna species of 2.0 and 1.8 kbp (denoted x and y). the pyvv capsid protein minor (cpm) gene was identified on the dsrna 3 species, and was subsequently cloned and sequen ... | 2002 | 12881642 |
