Figure 3.

Correlation between the EF and the other leaf growth variables. Correlation is shown between the EF and epidermal cell area (μm²; A), epidermal cell number (B), leaf 6 area (mm²; C), rosette leaf number (D), rosette relative leaf expansion rate (d⁻¹; E), and rosette leaf area (mm²; F). White circles and black triangles represent mean values of the considered growth variable for each genotype of the mutant collection and the RIL population, respectively. The linear relationship (dotted line) and the Pearson’s coefficient noted inside each graph (bottom right corner) correspond to the relation and the coefficient when all 200 genotypes are considered together. Asterisks indicate significant correlations, with values as follows: * P < 0.05, *** P < 0.001; ns indicates a nonsignificant correlation. Correlations were also tested by dividing the 200 genotypes in two subgroups: the mutant collection and the RIL population (Table I).
