Comparative Transcriptome Profiling of Nicotiana benthamiana Plants Infected with Potato Mop-Top Virus and Its Mutant Lacking a Gene for the 8K Protein Underlines the Role of Chloroplasts During Infection.

Abstract excerpt

Potato mop-top virus (PMTV) is a significant pathogen causing potato "spraing" disease worldwide. The PMTV 8K protein functions as a weak viral suppressor of RNA silencing (VSR), has viroporin activity, and plays a role in pathogenicity by promoting viral long-distance movement and modulating host responses. Uniquely, PMTV can establish systemic infection in the absence of the 8K protein, though the infection is...
