Table I. SMR1 rescued the multicellular phenotype of the sim-1 smr1-1 double mutant.

Nuclei/TIS, Nuclei per trichome initiation site, a measure of the number of cells per trichome initiation site. Statistical analysis was performed with one-way ANOVA. Letters indicate significant difference among the samples (P < 0.05).
