Figure 1 IAA Photodegradation Is Enhanced by PN. (A) Representative 4-day-old WT seedlings grown on 0, 1, or 10 µM IAA, with or without PN (25 µg ml–1), and under white light (WL) or yellow light (YL) conditions. Bar = 5 mm. (B) Graph of mean root length of 4-day-old WT seedlings grown on 0, 1, or 10 µM IAA, with or without PN (25 µg ml–1), and under white light (WL) or yellow light (YL) conditions. Error bars = standard error. n = 10 for all conditions, except for 10 µM IAA/WL/0 PN n = 9. (C) Representative 4-day-old WT seedlings grown under YL on 1 µM IAA, with varying concentrations of PN (0–25 µg ml–1). Plates were treated for 2 d prior to planting seeds with white light (WL) or yellow light (YL). Bar = 5 mm. (D) Graph of mean root length of 4-day-old WT seedlings grown under YL on 1 µM IAA, with varying concentrations of PN (0–25 µg ml–1). Plates were treated for 2 d prior to planting seeds with white light (WL) or yellow light (YL). Error bars = standard error. n = 8–10. (E) Spectra of 200 µM IAA in liquid MS media after exposure to 0, 24, 48, or 96h of white light. Blue line = IAA alone. Red line = IAA from the mixture of 200 µM IAA + 200 µM PN (obtained by subtracting out the absorbance due to 200 µM PN). Green line = IAA from the mixture of 200 µM IAA + 200 µM degPN (obtained by subtracting out the absorbance due to 200 µM degPN).
