  • The multicellular trichome phenotype of a complementation line homozygous for a single T-DNA insert for each of the indicated SMRs was assessed by counting the number of DAPI-stained nuclei at each trichome initiation site (TIS) for each genotype. All genotypes with an “a” have significantly fewer nuclei per TIS than the sim mutant (P < 0.0001 in a one-tailed t test, after applying a Bonferroni correction for multiple tests). For each transgenic genotype, at least two additional independent lines were obtained having a phenotype qualitatively equivalent to the line shown here.
