Structural 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 کاملNucleotide 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 کاملSpatio-temporal analysis of the RNAs, coat and movement (p7) proteins of Carnation mottle virus in Chenopodium quinoa plants.
Time-course and in situ hybridization analyses were used to study the spatio-temporal distribution of Carnation mottle virus (CarMV) in Chenopodium quinoa plants. Genomic and subgenomic RNAs of plus polarity accumulated linearly with time, whereas the corresponding minus strands reached a peak during infection in inoculated leaves. Analyses of serial tissue sections showed that plus polarity st...
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 کاملRNA-binding properties and mapping of the RNA-binding domain from the movement protein of Prunus necrotic ringspot virus.
The movement protein (MP) of Prunus necrotic ringspot virus (PNRSV) is involved in intercellular virus transport. In this study, putative RNA-binding properties of the PNRSV MP were studied. The PNRSV MP was produced in Escherichia coli using an expression vector. Electrophoretic mobility shift assays (EMSAs) using DIG-labelled riboprobes demonstrated that PNRSV MP bound ssRNA cooperatively wit...
