Pictures show representative root phenotypes in plants expressing C4 or the mutant forms C4CCLm1or C4CCLm2(T3 generation), at 7 dpg, after growing for 12 h rotated 90 with respect to their initial growing position: the newg-force direction is depicted in the pictures by the yellow arrow on the left. Scale bar, 1 cm. Note the wider aperture of the tip angle primary roots exhibit in plants expressing the C4 protein, indicated in the figure by the white dotted lines in root tips; a stable line expressing GFP (35S:GFP) is shown as reference.
