Transcription factor bHLH104.

Xanthotoxin 5-hydroxylase CYP82C4; Can hydroxylate xanthotoxin (8-methoxypsoralen) to form 5- hydroxyxanthotoxin (5-hydroxy-8-methoxypsoralen) in vivo and in vitro. Involved in the early iron deficiency response, possibly through an IDE1-like mediated pathway. Involved in the pathway of sideretin biosynthesis from feruloyl CoA, a redox-active catecholic metabolite exuded by roots in response to iron deficiency in order to facilitate the uptake of iron; this pathway consists in the successive conversion from feruloyl CoA to scopoletin, from scopoletin to fraxetin and from fraxetin to si [...]

Feruloyl CoA ortho-hydroxylase 1; 2-oxoglutarate (OG)- and Fe(II)-dependent dioxygenase (2OGD) involved in scopoletin biosynthesis. Converts feruloyl CoA into 6'-hydroxyferuloyl CoA but has no activity with ferulic acid, feruloylquinic acid, caffeic acid, caffeoyl CoA, p- coumaric acid, cinnamic acid, cinnamoyl CoA or benzoyl CoA. Required for the production and secretion of compounds (e.g. fluorescent coumarins) that facilitate the mobilization and uptake of iron from sources with low bioavailability or in high pH- induced iron deficiency conditions. Involved in the pathway of sideret [...]

Transcription factor bHLH104.

Ferritin-1, chloroplastic; Stores iron in a soluble, non-toxic, readily available form. Important for iron homeostasis. Has ferroxidase activity. Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation (By similarity).

Ferric reduction oxidase 3, mitochondrial; Ferric chelate reductase involved in iron reduction in roots. May participate in the transport of electrons to a Fe(3+) ion via FAD and heme intermediates.

Transcription factor bHLH104.

Fe(2+) transport protein 1; High-affinity iron transporter that plays a key role in the uptake of iron from the rhizosphere across the plasma membrane in the root epidermal layer. Acts as the principal regulator of iron homeostasis in planta. Also mediates the heavy metals uptake under iron-deficiency by its ability to transport cobalt, cadmium, manganese and/or zinc ions; Belongs to the ZIP transporter (TC 2.A.5) family.

Phosphate transporter PHO1; Inositol polyphosphate sensor that associates with transcription factors to regulate inorganic phosphate (Pi) starvation responses. Probably acts by binding inositol polyphosphate via its SPX domain. Acts as a Pi exporter, mediating efflux of Pi out of cells. Transfers Pi from the epidermal and cortical cells to the root xylem vessels. Involved in the transfer of Pi from roots to shoots. Involved in abscisic acid (ABA) induction of stomatal closure and ABA repression of stomatal opening. Belongs to the SYG1 (TC 2.A.94) family.
