↵^{a} The total number of cells and number of mitoses in each subdomain were counted and used for calculating the mitotic index (standard errors appear within parentheses).
↵^{b} The meristem diameter for Ler is 53.1 μm (0.9), and the meristem height is 13.3 μm (0.4).
↵^{c} The meristem diameter for clv3-1 is 81.6 μm (1.3), and the meristem height is 31.2 μm (0.7).
↵^{d} n, number of meristems. For each meristem, six median longitudinal sections were analyzed.
