Cell elongation and twisting profiles in an epidermal cell file in hypocotyls of Arabidopsis tubulin mutants. Wild type (WT) and tua6 were grown as in Figure 1. A, The length of individual cells from the top (cell 1) to the base (cell 20) was measured with SEM and elongation for 24 h was calculated. B, The alignment angle of individual cells was measured with SEM. Values are means ± se (n = 15).
