The Carnation mottle virus (CarMV) is a single positive-strand RNA virus belonging to the genus Carmovirus. The major natural host for CarMV is the carnation. In this study, using transcriptome data, we provide for the first time a nearly complete genome sequence of CarMV infecting hop plants.

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 ...

abstract during the winter and spring of 2007 and 2008, 450 samples (leaves of carnation plants) showing symptoms of yellowing, mottling, leaf malformation, and stunting were collected from greenhouses in mashhad and chenaran regions. the samples were tested by das-elisa for the presence of carmv. total rna was extracted by rnxtm (-plus) solution from positive infected samples confirmed in das-...

The complete nucleotide sequence of the maize chlorotic mottle virus (MCMV) genome has been determined to be 4437 nucleotides. The viral genome has four long open reading frames (ORFs) which could encode polypeptides of 31.6, 50, 8.9 and 25.1 kd. If the termination codons, for the polypeptides encoded by the 50 and 8.9 kd ORFs are suppressed, readthrough products of 111 and 32.7 kd result. The ...

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...

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...

The nucleotide sequence of the genomic RNA of barley yellow dwarf virus, PAV serotype was determined, except for the 5'-terminal base, and its genome organization deduced. The 5,677 nucleotide genome contains five large open reading frames (ORFs). The genes for the coat protein (1) and the putative viral RNA-dependent RNA polymerase were identified. The latter shows a striking degree of similar...

ABSTRACT A new carmovirus was isolated from Angelonia plants (Angelonia angustifolia), with flower break and mild foliar symptoms, grown in the United States and Israel. The virus, for which the name Angelonia flower break virus (AnFBV) is proposed, has isometric particles, approximately 30 nm in diameter. The experimental host range was limited to Nicotiana species, Schizanthus pinnatus, Myoso...

Calibrachoa mottle virus (CbMV) infects Calibrachoa, an important new horticultural plant in Europe and in the United States [1]. It belongs to the genus Carmovirus of family Tombusviridae and has a single stranded, positive-sense RNA genome of 3.919 kb (Genbank accession number GQ244431) [2]. Molecular analysis of the CbMV genomic sequence revealed the presence of at least five open reading fr...
