| identification and molecular characterization of a marafivirus in rubus spp. | an undescribed virus with isometric particles and a diameter of ca. 30 nm was identified in diseased samples of wild and cultivated rubus species and molecularly characterized. its genome was 6,463 nt, excluding the 3'-terminal poly(a) tail, and contained a single open reading frame coding for a 2,035-amino-acid-long precursor polypeptide (p223). the amino terminal portion of p223, identified as a replication-associated polyprotein, contained conserved motifs of methyltransferase, endopeptidase/ ... | 2009 | 19784756 |
