Shoot and root profiling of auxin metabolites in cZ biosynthetic mutants. Anthranilate (ANT), tryptophan (Trp), indole-3-pyruvic acid (IPyA), indole-3-acetonitrile (IAN), indole-3-acetic acid (IAA), 2-oxindole-3-acetic acid (oxIAA), 2-oxoindole-3-acetyl-1-O-ß-D-acetic acid glucose (oxIAA-glc), and indole-3-acetylglutamate (IAA-Glu) levels were quantified in (A) aerial tissues and (B) roots of Col-0, ipt29, ipt2, ipt9, 35Spro:IPT9 7-days-old seedlings. Concentrations are expressed in picomols per g of fresh weight. Error bars indicate standard error and asterisks indicate values significantly different from Col-0 in a Student's t test (* p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001; n ≥ 4).
