Key Points

To develop an artificial microRNA (amiRNA) system based on endogenous miRNA precursors to achieve targeted gene knockdown in the unicellular green alga Chlamydomonas reinhardtii.
Engineered artificial miRNAs targeting the MAA7 and RBCS1/2 genes using an endogenous Chlamydomonas microRNA precursor backbone.
Constructed a dimeric amiRNA precursor to evaluate simultaneous expression and multiplexed gene silencing.
Overexpressed amiRNAs cleaved MAA7 and RBCS1/2 transcripts precisely at predicted cleavage sites, causing substantial reductions in transcript accumulation and generating expected mutant phenotypes.
A single dimeric amiRNA precursor successfully yielded two distinct functional amiRNAs simultaneously to target multiple genes.
