Quantification of IAA and IAN in CYP79B2ox lines. Free IAA (A) and IAN (B) were measured for CYP79B2ox lines 1D1, 1D3, 1J3, and Col-0 grown in low light (18–30 μE m−2/sec) for 6 d after germination at 21°C. Values are given in nanograms per gram fresh weight of tissue, presented as the mean ± S.E.M. from three or four independent samples. Values for free IAA were subjected to Newman-Keuls ANOVA. Significant differences compared to Col-0 are indicated as p < 0.05 (*) and p < 0.001 (**).
