Fig 7. Expression validation of predicted targets in mutant regulator backgrounds.

Fig 7

Root tissue was collected from seedlings grown 4 days on iron sufficient media and transferred to iron deficient media for 3 days. Expression values are normalized to β-tubulin and to WT (Col-0) expression for each gene. Error bars indicate ±SEM (n = 4). Mutant backgrounds are (A)obp4-1, (B)wrky57-3, (C)etf9-1, (D)col4-1, (E)asil2-1, and (F)myb55-1. Asterisk indicates significant difference from WT (Student’s t-test, p < 0.05).
