An unusual and distinguishing feature of alfalfa mosaic virus (AMV) and ilarviruses such as tobacco streak virus (TSV) is that the viral coat protein is required to activate the early stages of viral RNA replication, a phenomenon known as genome activation. AMV-TSV coat protein homology is limited; however, they are functionally interchangeable in activating virus replication. For example, TSV ...

More than 90% of 3-week-old clones obtained from avian myeloblastosis virus (AMV)-induced myeloblasts differenti ate into mature cells when grown as colonies in semisolid medium. This was determined primarily by assaying colo nies on resistant cell feeder layers for the presence of myeloblasts. These colonies were also seeded onto suscepti ble cell feeder layers to assay for the presence of tra...

RNA sequence relatedness among avian RNA tumor virus genomes was analyzed by inhibition of DNA-RNA hybrid formation between 3H-labeled 35S viral RNA and an excess of leukemic or normal chicken cell DNA with increasing concentrations of unlabeled 35S viral RNA. The avian viruses tested were Rous associated virus (RAV)-3, avian myeloblastosis virus (AMV), RAV-60, RAV-61, and B-77 sarcoma virus. H...

This research assesses the influences of Atlantic Multidecadal Variability (AMV) on global tropical cyclones (TCs) using two large ensembles idealized climate model simulations with opposite signs AMV forcings superimposed (i.e., AMV+ and AMV–). We first detect TCs then compare TC activity by basin in experiments. find contrasting responses Pacific frequency to anomalies. Compared AMV–, signifi...

In contrast to most alfalfa mosaic virus (AMV) strains (YSMV, S, M and 425), AMV strains VRU and 1 5/64 can form abnormally long virus particles, an ability which has been linked to the coat protein (CP). In order to study this phenomenon, the CP-encoding RNAs 3 of AMV strains VRU and 1 5/64 were cloned and fully sequenced. Comparative sequence analyses of AMV RNA 3 sequences derived from diffe...
