MICRORNA CONSTRUCTS FOR THE SUPPRESSION OF THE EXPRESSION OF TARGETED GENES OR THE DOWN REGULATION OF TARGETED GENES AND METHODS THEREFORE

摘要

The invention provides methods and compositions useful in target sequencesuppression, target sequence validation and target sequence down regulation.The invention provides polynucleotide constructs useful for gene silencing orRNA down regulation, as well as cells, plants and seeds comprising thepolynucleotides. The invention also provides a method for using microRNA tosilence a target sequence or to down regulate RNA.
