Isolation of proteins involved in posttranscriptional gene silencing and methods of use

摘要

The present invention discloses transgenic plant cells transformed with a nucleic acid encoding a SrMV P1/HC-Pro protein, wherein expression of the protein suppresses post-transcriptional gene silencing in the cell. The transgenic plant cell may be located in an embryonic callus or in a mature plant. The plant may be a monocot plant.
