Exploring the landscape of miRNA production and the structural rules that shape it

Degradome sequencing of semi-active DCL1 mutants separates true miRNAs from DCL1-independent small RNAs in Arabidopsis thaliana and illustrates the processing pattern of 147 pri-miRNAs. In parallel, DMS-MaPseq decodes the in vivo secondary structures of pri-miRNAs, enabling a better understanding of cleavage modes and of the impact of DCL1 cofactors on cleavage.
