Acropetal Auxin Transport Measurements in Roots of the Wild Type (A17) and cre1 Mutants.

Auxin relative transport rate changes at 24 h after treatment are shown. Seedlings were treated with TIBA (A) or naringenin (B), either in the presence or absence of E65. A two-way ANOVA with a Tukey-Kramer multiple comparison post-test was used for statistical analyses (P < 0.05, n = 15 to 25). Different lowercase letters indicate significant differences in relative auxin transport rates. Graphs show mean and sd. W, water; N, naringenin.
