In situ measurements of trichome DNA contents of cpr5 single and double mutants. (A) Interaction of cpr5 alleles and try. (B) Interaction of cpr5-1 and proGL2:GL3. DNA contents of DAPI-stained nuclei are presented as Relative Fluorescent Units (RFU), normalized to 32 RFU for Col-0, based on an assumed DNA content of 32C for wild-type trichome nuclei. Measured RFU values should thus correspond approximately to DNA contents. Data are presented as Box Plots, where the box encompasses the 25th through the 75th percentile of the data, the line within the box is the median (50th percentile), and the error bars represent the 5th (lower bar) and 95th (upper bar) percentiles. Statistical analysis is given in Tables 2 and 4. For the proGL2:GL3 genotype in (B), a single data point at RFU = 1600 was omitted from the Figure for clarity of presentation, though this point was included in the analysis in Table 4.
