ARF18 — Medicago truncatula

Summary

MTR_5G040880 (ARF18) on barrel medic chromosome 5 encodes a protein with ARF and B3 DNA-binding domains. The gene is associated with transcription cis-regulatory region binding and DNA binding, and its product localises to the nucleus. ARF18 is associated with a wide range of biological processes including hormone anabolism, secondary metabolite biosynthesis, pattern specification, organogenesis, lateral root and root cap development, cell growth, chlorophyll breakdown, sulfur metabolism, exocytosis, autophagy, RNA processing, DNA damage response, cytokinin signalling, geotropism, chromatin modelling, response to virus, and NO storage. Trait associations include lateral root length, root length, auxin sensitivity, and nitrogen recycling. Studies of related genes in other species support the family's role in auxin-mediated development.
