Fig. 6From: Shoot iron status and auxin are involved in iron deficiency-induced phytosiderophores release in wheatEffect of indole acetic acid (IAA) supply on Fe-sufficient wheat plants (a) Phytosiderophores (PS) release by Fe-sufficient plants (+Fe) treated with IAA (0.1 or 1Ā Ī¼M); in Ī¼M (assuming a Fe-PS chelation 1:1) per g of root fresh weight. Harvests were performed at 4, 72 and 96Ā h of treatment, which corresponded to the three columns per treatment. Average of 3 replicates with 20 plants each. pā<ā0.05 (Tukey HSD test). b Relative root TaNAAT gene expression in Fe-sufficient plants (+Fe) treated with IAA (0.1 or 1Ā Ī¼M).
