Ectopic expression of LAX2 in Arabidopsis transgenic plants restores venation patterning in leaves of lax2 mutants. (A) Illustrative photographs of leaf number 5 and the corresponding inset showing a zoom on the third vein pair. The final image resulted from merging two photographs. Whole-leaf scale bar represents 2·0 mm, whereas leaf-inset scale bar represents 1·0 mm. (B) Average distance between the two attachment sites of the lateral veins of the third vascular pair. (C) Lateral-vein asymmetry index. Thin bars represent s.e.. Different letters indicate significant differences (P < 0·05, Tukey test).
