In yeast expressing the RNA replication proteins encoded by brome mosaic virus (BMV), B3URA3, a BMV RNA3 derivative that harbours the 3a cell-to-cell movement protein gene and the yeast uracil biosynthesis gene URA3, was replicated and maintained in 85–95% of progeny at each cell division. Transmission of the B3URA3 RNA replicon from mother to daughter yeast did not require the 3a gene. Nevertheless, even after passaging for 165 cycles of RNA replication and yeast cell division, each of 40 independent Ura+ colonies tested retained B3URA3 RNAs whose electrophoretic mobilities and accumulation levels were indistinguishable from those of the original B3URA3. These and other results suggest that unselected genes in many positive-strand RNA virus replicons can be stably retained if the presence of the gene does not confer a selective disadvantage in RNA replication.
