abstract：:The bipartite genomic RNAs of red clover necrotic mosaic virus (RCNMV) lack a 5' cap and a 3' poly(A) tail. RNA1 encodes viral replication proteins, and RNA2 encodes a movement protein (MP). These proteins are translated in a cap-independent manner. We previously identified two cis-acting RNA elements that cooperative...

Evidence is presented that there exist at least two pathways for viral attachment to cells, i.e., one mediated by the dispensable glycoprotein C (gC) and one independent of that glycoprotein. Thus, whereas th...
