Enhancing expression of a silenced target sequence in plants using plant viral enhancers and amplicons

摘要

Compositions and methods for modulating gene expression in plants are provided. The methods comprise the use of a gene silencer (amplicon) in combination with an enhancer sequence (suppressor of co-suppression). Amplicons comprise a targeting sequence corresponding to the gene of interest, the target gene. The amplicon will direct gene silencing against a sequence with homology to the targeting sequence, (the target sequence). The amplicon may optionally comprise a promoter and a sequence that corresponds to at least a part of a viral genome.
