ABC1 — Phaseolus vulgaris

Summary

PHAVU_003G172700 (PvABC1) on chromosome 3 of French bean encodes a protein with SUF_FeS_clus_asmbl_SufB, SufBD_N, SUF_FeS_clus_asmbl_SufBD_sf, SUF_FeS_clus_asmbl_SufBD_core, and Fe-S_cluster_assembly_SufBD domains, and is annotated with ATP-coupled transmembrane transporter activity, transmembrane transporter activity, and protein binding. The gene is associated with cellular iron ion homeostasis, regulation of response to red or far red light, and detoxification, and its product localises to the chloroplast stroma. Annotated associations include chlorophyll degradation, light responsiveness, and iron-sulfur cluster assembly. Related genes in other species link the family to iron homeostasis and elongated hypocotyl in far-red light, while sequence similarity connections extend to traits such as shoot dry weight, manganese concentration, root length, and photochemical quenching.
