Artificial microRNA (amiRNA) technology offers highly specific and versatile gene silencing in diverse plant species. The principal challenge in amiRNA application is to select potent amiRNAs from hundreds of bioinformatically designed candidates to enable maximal target gene silencing at the protein level. To address this issue we developed the epitope-tagged protein-based amiRNA (ETPamir) screens, in which single or multiple target genes encoding epitope-tagged proteins are constitutively or inducibly co-expressed with individual amiRNA candidates in plant protoplasts. Accumulation of tagged proteins, detected by immunoblotting with a commercial tag antibody, inversely and quantitatively reflects amiRNA efficacy in vivo. The core procedure, from protoplast isolation to identification of optimal amiRNA, can be completed in 2-3 days. The ETPamir screens circumvent the widespread shortage of plant antibodies and the complexity of plant amiRNA silencing at target mRNA or/and protein levels. This method can be extended to verify predicted endogenous target genes for plant natural miRNAs.
