Figure 5.

Leaves arising from plants with opposing phyllotactic directions possess different degrees of asymmetry. (A) asymPC1 values for abaxial-top images separated by leaves arising from clockwise (gray, CL) and counter-clockwise (orange, CC) plants. Note the more extreme asymmetry exhibited by leaves from CC plants. x-axis shows node position (lower values closer to the apex). Superimposed upon barplots are loess regression lines with standard error bands. (B) The same as shown in (A), except for adaxial-bottom images. Note that the values are mirror images of those shown in (A), as the adaxial-bottom image of a leaf is the mirror of the abaxial-top image. Again, leaves arising from counter-clockwise plants exhibit more extreme asymmetry.
