additional information | silencing of the transcripts of StRDR1a and StRDR1b by dsRNA hairpin transcripts, expression of silencing constructs for StRDR1 does not affect the expression of the StRDR2 or the StRDR6 genes. Gene silencing does not affect the plant susceptibility to plant viruses, potato virus Y, potato virus X, and tobacco mosaic virus | Solanum tuberosum |

General Information | Comment | Organism |
---|---|---|
evolution | the enzyme belongs to the RDR gene family, phylogenetic analysis of RDR genes present in potato and in a range of other plant species, overview | Solanum tuberosum |
malfunction | StRDR1 transcript accumulation decreases in transgenic potato plants constitutively expressing a hairpin construct. These plants when challenged with three viruses, potato virus Y, potato virus X, and tobacco mosaic virus show no increase in the susceptibility of potato to these viruses. Suppression of StRDR1 gene expression does not increase in the susceptibility to the viruses | Solanum tuberosum |
physiological function | cellular RNA-dependent RNA polymerases catalyze synthesis of double-stranded RNAs that can serve to initiate or amplify RNA silencing. Enzyme RDR1 contributes to basal virus resistance in several plants | Solanum tuberosum |
