ABSTRACT:
This invention relates to an isolated nucleic acid fragment encoding a RNA-directed RNA polymerase. The invention also relates to the construction of a chimeric gene encoding all or a substantial portion of the RNA-directed RNA polymerase, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the RNA-directed RNA polymerase in a transformed host cell.
