Spatial variation in the mutation rate within the plant shoot apical meristem Open
The potential impact of new mutations on organismal function and evolution depends on the developmental fate of the affected cells. Stem cells in the shoot apical meristem form much of the plant body, but only those in the L2 can form game…
