Figure 2.

The number of cortical cells in the proximal meristem is reduced in ttl1 mutant in correlation with the deceleration of root growth rate observed in osmotic stress condition. The figure shows the number of cortical cells in the proximal meristem (A) and the cortical mature cell length (B) for Col-0 and ttl1 grown during 7 days in control, −0.7 MPa and −1.2 MPa osmotic stress conditions. Values are means ± standard deviation (SD). Different letters indicate statistically significant differences (t Student p < 0.05; n = 10). The experiments were repeated three times.
