Abstract

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.

探索 miRNA 的产生过程及其结构规则
对半活性 DCL1 突变体进行降解组测序,将拟南芥中真正的 miRNA 与不依赖 DCL1 的小 RNA 区分开来,并说明了 147 个 pri-miRNA 的加工模式。与此同时,DMS-MaPseq 对 pri-miRNA 的体内二级结构进行了解码,从而更好地了解了裂解模式以及 DCL1 辅因子对裂解的影响。
