Numbers in parentheses indicate the number of individuals/leaves analyzed. The wild-type plants or embryos are siblings of the corresponding mutants. All data are expressed as the mean ± se. nd, not determined.
a
Cells were counted along a cortex cell file of the embryo from the root tip to the cotyledons.
b
Significant differences with the wild type (t test, P < 0.01 for cortex cell number of the embryo and analysis of variance; P = 0.021 for number of leaf pavement cells).
