Figure 2. Frequency distribution of vein densities in the deletion mutant population and their control in the screen.

Values above chart bars denote the number of mutant plants for each high vein density. Distribution frequencies of deletion mutant and control plants were largely the same. Differences were at the extremity of the binomial curve at higher vein densities (930 (1.2%), 112 (0.14%) and 13 (0.02%) mutant plants for respectively 6.5, 7 and 7.5 veins mm⁻¹) where lines were selected as potential candidate mutants for increased vein density.
