ABC1 — Cicer arietinum

Summary

LOC101512937 (CaABC1) on chickpea chromosome 4 encodes a protein with an ADCK3 domain, an atypical kinase ADCK domain, an ABC1 domain, and a kinase-like domain superfamily, and is annotated with transmembrane transporter activity. The gene is associated with cytochrome complex assembly, ubiquinone anabolism, chlorophyll breakdown, and response to UV-B, and its product localises to mitochondria. CaABC1 has been connected to shoot dry weight, manganese concentration, and root length, as well as to protoporphyrin IX accumulation, hypocotyl elongation, and far-red light responsiveness. Studies of related genes in other species link the family to far-red light sensitivity, hypocotyl morphology, oxidative stress response, salt tolerance, and kin recognition.
