Chicken myeloblasts transformed by avian myeloblastosis virus (AMV) in the absence of nondefective helper virus (termed nonproducer cells) were found to release a defective virus particle (DVP) that contains avian tumor viral gag proteins but lacks envelope glycoprotein and a DNA polymerase. Nonproducer cells contain a Pr76 gag precursor protein and also a protein that is indistinguishable from...

The inhibition of human immunodeficiency virus (HIV) reverse transcriptase by certain antibiotics and related compounds was studied in comparison with that of avian myeloblastosis virus (AMV) reverse transcriptase and cellular DNA polymerases alpha and beta. In general, compounds that inhibited HIV reverse transcriptase also inhibited AMV reverse transcriptase. For example, 10 micrograms/ml of ...

Abstract The Tibetan Plateau (TP), referred to as the “Asian water tower,” contains one of largest land ice masses on Earth. local glacier shrinkage and frozen-water storage are strongly affected by variations in surface air temperature over TP (TPSAT), especially springtime. This study reveals that relationship between February North Atlantic Oscillation (NAO) March TPSAT is unstable with time...

Inhibitor of apoptosis (iap) genes have been identified in the genomes of two independent families of insect viruses, the Baculoviridae and the Entomopoxvirinae. In this report, we examined the functional attributes of the Amsacta moorei entomopoxvirus-encoded IAP protein (AMV-IAP). The binding specificity of the individual baculoviral IAP repeat (BIR) domains of AMV-IAP was investigated by usi...

Requirements for capped leader sequences for use during transcription initiation by tomato spotted wilt virus (TSWV) were tested using mutant alfalfa mosaic virus (AMV) RNAs as specific cap donors in transgenic Nicotiana tabacum plants expressing the AMV replicase proteins. Using a series of AMV RNA3 mutants modified in either the 5'-non-translated region or in the subgenomic RNA4 leader, seque...

Abstract The connection between the Atlantic meridional overturning circulation (AMOC) and multidecadal variability (AMV) is inspected in a suite of pre‐industrial integrations from 6th phase Coupled Model Inter‐comparison Project (CMIP6), using change‐point detection method to identify different AMOC‐AMV co‐variability regimes. A key finding this study that models robustly simulate multi‐decad...
