Asymmetry in Arabidopsis Leaves with Respect to Phyllotactic Direction.

(A) Asymmetric variation in shape explained by PC1 in leaves of Columbia-0. Arrows indicate laminar bulges.

(B) PC1 values from Arabidopsis differ across the leaf series such that C leaves have higher PC1 values than CC leaves (P = 0.00012).

(C) Significantly higher PC1 values in leaves from C plants indicate increased laminar outgrowth on the descending (Des.) side of leaves. The descending side of leaves arising from C (orange) and CC (black) plants is indicated by appropriately colored text.

(D) Outlines of leaves from C and CC plants with asymmetries characteristic of those statistically observed.
