Figure 3. Repression of a firefly luciferase reporter gene by Aux/IAA proteins fused to a GAL4 DNA binding domain.

Aux/IAA proteins fused to GAL4 DNA binding domains were co-transformed with a firefly luciferase reporter into Arabidopsis protoplasts. All luciferase activities were normalized relative to the empty effector vector (GAL4-DBD) and an internal luciferase control (renilla luciferase). Error bars: SD, n = 3, p≤0.001.
