A protein called Suppressor of Gene Silencing 3 (SGS3) protects RNA from degradation before it can be transformed into dsRNA during plant post-transcriptional gene silencing pathways. Complete loss-of-functionsgs3 mutants lack mature siRNAs, and complete gain-of-function mutations would exhibit high levels of both mature siRNAs and other cleavage products. A newly identified mutant overaccumulates one type of RNA cleavage product but has fewer mature siRNAs. This mutation that displays a novel phenotype is most likely what type of mutation?
