Mp1g06440	MpFRH1	experimental subject	The microRNA FRH1 (MpFRH1) mediates lateral inhibition by repressing RSL1; modeling shows FRH1 diffusion/mobility generates a diffusion-driven switch with a sharp transition between uniform and patterned states, associated with a subcritical Turing bifurcation at criticality.
Mp3g17930	MpRSL1	experimental subject	The rhizoid-specific transcription factor RSL1 (MpRSL1) is the local activator in the patterning model; mathematical modeling combining published and original data shows rhizoid patterning is consistent with local RSL1 activation modulated by lateral inhibition, reproducing wild-type and mutant spatial statistics.
