Small RNAs Turn Over a New Leaf as Morphogens

Dev Cell. 2017 Nov 6;43(3):253-254. doi: 10.1016/j.devcel.2017.10.025.

Abstract

In this issue of Developmental Cell, Skopelitis et al. (2017) demonstrate that sharp boundaries of gene expression can be created by threshold-based readout of mobile small RNA gradients. Support for this hypothesis comes from manipulation of small RNAs involved in top-bottom leaf patterning and from a novel synthetic biology approach.
