Auxin-induced expression levels for selected auxin response genes in control (DR5:GUS) seedlings and seedlings transformed with 35S:HA-IAA17mImII (line D2-14). Seven-day-old seedlings were removed from agar plates and incubated in a solution containing 1 μm 1-NAA for 1 h. qRT-PCR was used to determine the expression levels of genes indicated. See Figure 6 for additional details on the genes analyzed and presentation of the data. a, DR5:GUS control; b, 35S:HA-IAA17mImII.
