In plants, pri-to-pre-miRNA conversion also requires interaction of an RNA-binding protein HYPONASTIC LEAVES 1 (HYL1) and a C2H2-zinc finger protein SERRATE in nucleus.
After creation of plant pri-miRNA, a complex consisting of Dicer Like 1 enzyme (DCL1), the double-stranded RNA-binding protein HYL1 (hyponastic leaves 1), and the zinc-finger protein SE (serrate), with an assistance of the nuclear cap-binding complex, cleaves pri-miRNA to pre-miRNA [22, 28].
