  • a Values represent the mean shoot apical meristem diameter ± standard error (see Methods).

  • b Age indicates the days after germination plants were collected.

  • c n indicates the number of measurements used to determine size.

  • d The mean meristem diameter for clv2-1 is significantly different from that of clv2-1 cna-1 plants (t test, P < 0.01).

  • e The mean meristem diameter for clv3-2 is significantly different from that of clv3-2 cna-1/CNA plants (P = 0.03), clv3-2 cna-1 plants (t test, P < 0.01), and clv3-2 cna-2 plants (P < 0.01).

  • f The mean meristem diameter for clv1-7 is significantly different from that of clv1-7 cna-1 plants (t test, P < 0.01).
