Zygotic microRNAs coordinate the clearance of maternal mRNA in animals to facilitate developmental transitions. In a recent issue of Genes and Development, Nodine and Bartel (2010) uncover a reciprocal function in plants, where miRNA-156 preemptively represses genes that function later in development to prevent premature developmental transitions.
