Figure 6.

Organ-specific expression of the DR5-GUS and IAA genes. Seven-day-old WT seedlings transgenic for a DR5-GUS gene were dissected into shoots (S) and roots (R) before (control) and after treatment with 10 nm BL for 6 h or 1 μm IAA for 1 h. The abundance of GUS (A), IAA5 (B), and IAA19 (C) transcripts was analyzed using Taq-Man RTQ RT-PCR. Transcript levels are presented as values relative to those for control shoots, defined as 1, after normalization to the 18S ribosomal RNA levels. The data are the means ± se of the results of three independent hormone treatment experiments.
