Nuclear dicing bodies are nuclear bodies that play an important role in miRNAs play a control of gene expression. In plant cells, miRNA processing is a two-step process that takes place inside the nucleus by the enzyme Dicer-like1 (DCL1) and other proteins such as Serrate (SE), a zinc-finger domain protein, and Hyponastic Leaves1, a double-stranded RNA (dsRNA) binding-domain protein (HYL1). It is recently found that dicing bodies are phase separated condensates and their assembly is driven by the phase separation of SE (17442570, 33288888).
