Involved in the regulation of shoot development and salicylic acid (SA) homeostasis. Binds 1 Fe(2+) ion per subunit. Expressed in coleoptiles, leaf sheaths, leaf blades and root tips of young seedlings (PubMed:31701152). Expressed in vascular bundles of mature leaf blades (PubMed:31701152). Expressed in developing culms and nodes (PubMed:31701152). Plants overexpressing SLC1 are infertile and exhibit defects in shoot development characterized by slender and crinkly leaves. Belongs to the iron/ascorbate-dependent oxidoreductase family. Truncated N-terminus. Truncated N-terminus.
