Free indole-3-acetic acid (IAA) quantification in Arabidopsis thaliana inflorescence stem segments
| Apical segment | Middle segment | Basal segment | |
|---|---|---|---|
| Wild-type | 207 ± 50 | 253 ± 23 | 247 ± 27 |
| ugt78d2 | 194 ± 17 | 118 ± 14* | 142 ± 18* |
Free IAA was measured in three consecutive stem segments (pmol g−1 FW). The mean values ± SE of three independent biological samples (one sample is a pool of four to six individual stem segments) are displayed. Statistical analyses were performed by a paired t-test for uneven variance for each part of the stem between the two genotypes (*, P < 0.05).
