RFU = relative fluorescence units. s.d. = standard deviation. N = number of nuclei examined. RFU values have been normalized to 32, the expected value for trichome nuclei of the wild-type Col strain, and thus RFU values should roughly correspond to DNA contents. A Kruskal-Wallis One Way ANOVA indicated that differences in the medians were greater than expected by chance (p < 0.001); an all pairwise multiple comparison (Dunn's Method) indicated that all pairwise comparisons were significantly different (p < 0.05) except cpr5-1 vs. cpr5-1 try-JC and cpr5-2 vs. cpr5-2 try-JC.
