(Submitter supplied) Small RNAs recently emerged as a new class of mobile instructive signals in development. Here, we investigate their mechanism of action and show that the gradients formed by mobile small RNAs generate sharply defined domains of target gene expression. By modulating the source of artificial miRNAs we show that boundary formation is an inherent property of the small RNA gradient itself. The threshold-based readout of such gradients is highly sensitive to small RNA levels at the source, allowing plasticity in the positioning of a target gene expression boundary. more...
