A tymovirus was isolated in Brazil from tomato plants with severe symptoms of leaf mosaic and blistering. The virus was mechanically transmissible to solanaceous indicator host species. The infected plants contained icosahedral particles and chloroplasts with membrane deformations which are typical cytopathic effects caused by tymoviruses. Its coat protein amino acid sequence shares the maximum of 64 % identity with the tymovirus Chiltepin yellow mosaic virus, which suggested that it can be… 
Complete genome sequence of a proposed new tymovirus, tomato blistering mosaic virus
The complete genome sequence of ToBMV was determined and shown to have a size of 6277 nucleotides and three ORFs: ORF 1 encodes the replication-complex polyprotein, ORF 2 the movement protein, and ORF 3 the coat protein.
Chloroplast Proteome of Nicotiana benthamiana Infected by Tomato Blistering Mosaic Virus
This work investigated the chloroplast proteomic profile of ToBMV-infected N. benthamiana using bidimensional electrophoresis (2-DE) and mass spectrometry to study the virus-host interaction related to the virus replication and infection, and identified proteins that may be targets of a direct interaction with viral proteins.
A highly divergent isolate of tomato blistering mosaic virus from Solanum violaefolium
The sequence analysis of this ToBMV isolate suggests that the demarcation criterion of 80 % overall genome sequence identity in the genus Tymovirus may require revision.
Complete Genome Sequence of a Tobacco-Infecting, Tomato-Blistering Mosaic Virus
The complete genome sequence of a new tomato-blistering mosaic virus (ToBMV) isolate was determined and it shares 88% nucleotide identity with the ToBMV isolated from tomato.

Global Advances in Tomato Virome Research: Current Status and the Impact of High-Throughput Sequencing
It is observed that the rate of tomato virus discovery is accelerating in the past few years due to the use of HTS, but the extent of the post-discovery characterization of viruses is lagging behind and is greater for economically devastating viruses, such as the recently emerged tomato brown rugose fruit virus.

Petunia vein banding virus: Characterization of a New Tymovirus from Petunia × hybrida.
Petunia vein banding virus was transmitted only with difficulty to healthy petunia plants, however, from an experimentally infected petu-nia, it was later readily transmitted also to Nicotiana benthamiana and Nicandra physalodes, but not to other species in the Solanaceae or other plant families.
Identification and Functional Analysis of the Turnip Yellow Mosaic Tymovirus Subgenomic Promoter
It is reported that the subgenomic promoter sequence of TYMV is located on a 494-nucleotide fragment, containing previously identified highly conserved sequence elements, shown here to be essential for promoter function.
Molecular characterization of isolates of anagyris vein yellowing virus, plantago mottle virus and scrophularia mottle virus – comparison of various approaches for tymovirus classification
Total nucleotide and coat protein amino acid sequence identities revealed similar groupings in the genus tymovirus as serological studies did, however, the latter tended to suggest much closer relationships than the molecular data and may fail to recognise the distinctiveness of new tyMovirus species.

Turnip yellow mosaic virus is a positive strand RNA virus of the alphavirus-like supergroup of the family Tymoviridae and has a narrow host range almost completely restricted to the Cruciferae.
The tymobox, a sequence shared by most tymoviruses: its use in molecular studies of tymoviruses.
The 5'-terminal sequences of the virion protein mRNAs of ononis yellow mosaic and kennedya yellow mosaic tymoviruses were determined, and also the positions in the genomes of the transcription
Nemesia ring necrosis virus: a new tymovirus with a genomic RNA having a histidylatable tobamovirus-like 3' end.
The complete nucleotide sequence of the genomic RNA of the new virus Nemesia ring necrosis virus (NeRNV), which is widespread in various ornamental plant species belonging to the Scrophulariaceae and
Use of degenerate primers in the polymerase chain reaction to detect whitefly-transmitted geminiviruses
Degenerate PCR primers were designed to anneal to highly conserved nucleotide sequences identified in the genomes of 10 whitefly-transmitted geminiviruses, and tested for their effectiveness in the amplification of viral DNA fragments from the DNA-A and/or DNA-B components of 15 previously uncharacterized geminIViruses.
Análise ultra-estrutural de folhas de três espécies de Solanaceae após inoculação com o vírus da necrose branca do tomateiro (VNBT - Tymovirus)
The leaf ultrastructure of Nicotiana glutinosa L., Lycopersicon pimpinellifolium L., and Physalis angulata L. inoculated with the tomato white necrosis virus (TWNV - Tymovirus) was analysed. Plants
Targeting of the Turnip Yellow Mosaic Virus 66K Replication Protein to the Chloroplast Envelope Is Mediated by the 140K Protein
Analysis of the subcellular localization of the 140K protein fused to GFP demonstrated that it is targeted to the chloroplast envelope in the absence of other viral factors and that it induces the clumping of the chloroplasts, one of the typical cytological effects of TYMV infection.
