Yeast as a model host to study replication and recombination of defective interfering RNA of Tomato bushy stunt virus.


Defective interfering (DI) RNA associated with Tomato bushy stunt virus (TBSV), which is a plus-strand RNA virus, requires p33 and p92 proteins of TBSV or the related Cucumber necrosis virus (CNV), for replication in plants. To test if DI RNA can replicate in a model host, we coexpressed TBSV DI RNA and p33/p92 of CNV in yeast. We show evidence for… (More)
