Nucleotide sequence and genome organization of carnation mottle virus RNA.
The complete nucleotide sequence of carnation mottle genomic RNA (4003 nucleotides) is presented. The sequence was determined for cloned cDNA copies of viral RNA containing over 99% of the sequence and was completed by direct sequence analysis of RNA and cDNA transcripts. The sequence contains two long open reading frames which together can account for observed translation products. One transla...
متن کاملAn encapsidated, subgenomic messenger RNA encodes the coat protein of carnation mottle virus.
The translation strategy of carnation mottle virus (CarMV) in vitro has been generally assumed to involve internal initiation events on full-length, genomic RNA (4.3 kb). We suggest that this is, at least in part, incorrect. Encapsidated RNA, fractionated on denaturing sucrose gradients, or total RNA from CarMV-infected leaves, fractionated under non-denaturing conditions, was translated in an ...
متن کاملStructural properties of carnation mottle virus p7 movement protein and its RNA-binding domain.
Plant viral movement proteins (MPs) participate actively in the intra- and intercellular movement of RNA plant viruses to such an extent that MP dysfunction impairs viral infection. However, the molecular mechanism(s) of their interaction with cognate nucleic acids are not well understood, partly due to the lack of structural information. In this work, a protein dissection approach was used to ...
متن کاملUncoating Mechanism of Carnation Mottle Virus Revealed by Cryo-EM Single Particle Analysis
Genome uncoating is a prerequisite for the successful infection of plant viruses in host plants. Thus far, little is known about the genome uncoating of the Carnation mottle virus (CarMV). Here, we obtained two reconstructions of CarMV at pH7 in the presence (Ca-pH7) and absence (EDTA-pH7) of calcium ions by Cryo-EM single particle analysis, which achieved 6.4 Å and 8 Å resolutions respectively...
متن کاملHigh molecular weight RNA from avian myeloblastosis virus.
Avian myeloblastosis virus produced in vitro by myeloblastic cells in suspension was labeled with 32P and 14Camino acids. After partial purification of the virus, and pronase digestion, an RNA was extracted by phenol into the aqueous phase. Glycerol gradient centrifugation showed that the 32P-labeled RNA con tained 2 distinct components: a high molecular weight fraction sedimenting at about 67 ...
