Figure 6.

Comparison of the effect of DAS534 and 2,4-D on previously characterized mutants. Measurements were performed as described in Figure 2. Root lengths (±sd) for untreated controls were 21.5 (±1.8), 21.2 (±3.2), 24.1 (±3.1), 20.0 (±2.1), 25.0 (±2.1), and 31.5 (±3.1) mm for Col-0, afb5-1, sgt1b-4, edm1, tir1-1, and axr1-3 plants, respectively. A, Effect of DAS534 on edm1 and sgt1b-4. The deletion mutant line edm1 lacks seven genes (At4g11220–At4g11280), including SGT1b (Tor et al., 2002). Effect of DAS534 (B) and 2,4-D (C) on axr1-3 and tir1-1 compared with afb5-1 and sgt1b-4. Symbol labeling is shown in B and is the same for C.
