WebbThis was confirmed from the full sequence of the coat protein gene and a partial sequence of the replicase gene. Sequence analysis revealed that TMV isolated from diseased petunia had high identity (ca. 98–99) with TMV vulgare … WebbThis is supported by gene expression data indicating that 30% of the Arabidopsis genes displaying transcriptional alterations in response to TMV contain multiple auxin response promoter elements. Combined, these data indicate that the TMV replicase protein interferes with the plant's auxin response system to induce specific disease symptoms.

WebbEffects of TMV replicase protein. As was previously mentioned, the TMV replicase complex, translated immediately after viral disassembly, is composed of two 5′ ORFs which encode 183 and 126 kDa proteins. The replicase complex is associated with virus replication and, in particular, the 126 kDa component has been identified as the TMV VSR.
