Fig. 4. Cell morphogenesis defects in clasp mutants. (A) Wild-type (Col) and clasp mutant trichomes. The graph depicts the fraction of trichomes with different numbers of branch-points. (B) Comparison of trichome branch alignment on the an mutant and an clasp double mutant rosette leaf. Right panel shows the distribution of trichome branch alignment angles (degree) relative to the leaf longitudinal axis. 290 an and 160 an clasp trichomes were measured in total. (C) Wild-type and clasp mutant pavement cells. As a measurement of puzzle cell shape, cell shape factor (4
x area/perimeter2) of the clasp mutant and wild type is compared in the right panel. Scale bar: 200 µm (A), 50 µm (C).
