Categories Used for Dominant Polyploid Mutant Screening.

(A) Relative ratio of each cell ploidy of the wild type (Col-0) and ctr1-1. Approximately 5000 nuclei were counted in the wild type and ctr1-1 mutant.

(B) Ratio of 8C/32C and 16C/32C of dark-grown seedlings of the wild type (Col-0), ctr1-1, and a mixture of Col-0 and ctr1-1 at a ratio of 3 to 7. Black bars indicate the categories used for mutant screening.

For each ploidy measurement, at least 20 seedlings were used, and it was replicated three times. Error bars indicate standard deviation.
