Mirtrons are a type of microRNAs that are located in the introns of the mRNA encoding host genes. All the miRNAs in plants are derived from the sequential DCL1 cleavages from pri-miRNA to give pre-miRNA (or miRNA precursor), but the mirtrons bypass the DCL1 cleavage and enter as pre-miRNA in the miRNA maturation pathway.
