Expression of DR5:GUS in Root Transition Zones Correlates with Total Root Length.

(A) Expression patterns of the DR5:GUS auxin reporter in roots of 3-d-old etiolated Col-0 and aux1-7 seedlings grown in the absence (air) or presence (ACC) of 10 μM ACC. GUS staining was performed overnight. Imaging conditions were identical for all of the plants in the experiment. The images displayed are representative of at least three independent experiments with >20 seedlings examined per experiment.

(B) Expression patterns of the DR5:GUS auxin reporter in 3-d-old etiolated Col-0 seedlings grown in the presence of 10 μM ACC and rty1-1 seedlings grown in the absence of ACC. The top panel depicts three representative seedlings per genotype/treatment, while the bottom panel shows enlarged images of corresponding root tips. The images displayed are representative of two independent experiments.
