Root meristem develooment the quiescent centre is essential for meristem function by maintaining adjacent cells in stem-cell mode (always regenerates first, when the meristem is ablated) despite a stereotypic cleavage pattern, cells in the root differentiate position-dependent rather than lineage dependent (mutants, ablation studies) auxin organizes root patterning (high near quiescent centre), but different downstream genes mediate differentiation (same signal, different effector) 15...
