Resistance of afb5 and sgt1b and three other auxin-resistant mutants to various herbicidal auxins
Root lengths were measured as described in Figure 2. The fold increase in resistance was calculated by dividing the mutant root GR50 by the wild-type GR50. ND, Not determined.
| Mutants | Fold Increase in Resistance over Wild Type

|---|---|---|---|---|
| DAS534 | Picloram | 2,4-D | IAA | |
| afb5 | 5.6 | 26 | 1.5 | 0.4 |
| sgt1b | 8.4 | 60 | 1.8 | 0.7 |
