ARF16 — Brassica juncea

Summary

BJUB05G590S (BjARF16) on chromosome B05 of Indian mustard encodes a protein with ARF, B3, and PB1-like domains, and is a DNA-binding transcription factor. The gene product localises to the nucleus and is associated with miRNA binding and transcription cis-regulatory region binding. BjARF16 is linked to auxin signalling and response, as well as leaf development, leaf senescence, callus formation, pattern specification, cell division, and DNA-dependent transcription. It has been connected to seed weight, seed dormancy, seed germination, root cap formation and development, lateral root formation, root system development, columella cell differentiation, distal stem cell differentiation, somatic embryogenesis, plant growth, heat tolerance, ABA response, aluminum response, hypocotyl elongation, abaxial identity, and root growth inhibition. Studies of related genes in other species link the family to columella stem cell number.
