Trans-acting siRNA

 
Wikipedia: Trans-acting siRNA

Trans-acting siRNA (ta-siRNA or tasiRNA) is a form of small interfering RNA (siRNA) that represses gene expression through post-transcriptional gene silencing in land plants.[1] It is transcribed from the genome to form a polyadenylated, double-stranded precursor. Unlike other siRNAs, but like microRNA, ta-siRNA does not require full complementarity to its target RNA to have an effect.[2]
