Fig. 6.

Leaf phenotypes of plants with reduced FIL, ETT and ARF4 activity. a Representative images of leaf phenotypes of wild type (WT), fil-8, ett arf4, fil/+ ett arf4 and fil-8 ett arf4. I-III indicate the different phenotypic classes observed. I simple leaves; II lobed leaves; III divided leaves and leaves bearing ectopic meristems (inset). Scale bars: 1 cm and 1 mm (inset). b Quantification of number of leaves in each phenotype class shown in a. The error bars are proportional to the standard error of the pooled percentage computed using binomial distribution *** P < 0.00001, two-tailed Mann–Whitney U test relative to ett arf4. n = 87 and 81 for WT and fil-8. n = 104, 148 and 64 for ett arf4, fil/+ ett arf4 and fil ett arf4.
