Specification of embryonic shoot stem cells via a small RNA-driven morphogenic circuit
The small RNA tasiARF initiates a self-reinforcing morphogenic circuit connecting cell wall mechanics, auxin signaling, and regulated cell division to specify embryonic shoot stem cell fate, revealing how lineage-specific regulatory innovation can preserve a conserved developmental output across divergent embryonic architectures.
