Figure 8.

Flow cytometric analysis of nuclear DNA content. Nuclei were isolated from fully expanded 29-d-old first leaves and subsequently analyzed by flow cytometry. A, Distribution of the ploidy level in wild type and compensation-exhibiting mutants. The results represent the average of six replicates from two independent experiments, using about six first leaves for each measurement. Data are represented as the mean ± sd (n = 6, from two independent sets). B, Scatter plot of the EF values plotted against relative average cell size.
