Expression -- Description ? help Back to Top
Source	Description
Uniprot	TISSUE SPECIFICITY: Expressed in roots and inflorescence, and to a lower extent, in leaves and stems. In roots, confined to the outer cell layers, specifically in the differentiation zone. Also detected in the endodermis and inner tissues of the central cylinder. {ECO:0000269\|PubMed:12679534, ECO:0000269\|PubMed:15539473, ECO:0000269\|PubMed:15556641}.

Functional Description ? help Back to Top
Source	Description
UniProt	Transcription factor. Essential protein involved in iron uptake responses. Regulates FRO2 at the level of mRNA accumulation and IRT1 at the level of protein accumulation. Confers enhanced iron mobilization responses at low iron supply. {ECO:0000269\|PubMed:15539473, ECO:0000269\|PubMed:15556641, ECO:0000269\|PubMed:16117851}.

Regulation -- Description ? help Back to Top
Source	Description
UniProt	INDUCTION: In roots by iron deficiency. Repressed by cytokinins. Induced by cold, UV, ethylene (ACC), jasmonic acid (JA), flagellin, and salicylic acid (SA) treatments. {ECO:0000269\|PubMed:12679534, ECO:0000269\|PubMed:15531708, ECO:0000269\|PubMed:15539473, ECO:0000269\|PubMed:15556641, ECO:0000269\|PubMed:18397377}.
