ARF3 — Beta vulgaris subsp. vulgaris

Summary

BVRB_8G182410 (ARF3, BvARF3) on sugar beet chromosome 8 encodes a protein with B3 DNA-binding and ARF domains, and is associated with chromatin DNA binding, transcription factor activity, protein heterodimerization activity, protein homodimerization activity, DNA binding, transcription cis-regulatory region binding, and protein binding. It is associated with auxin signalling and metabolism, lateral root emergence and development, seed development and size regulation, vegetative and reproductive structure development, and fruit ripening. The gene is linked to abaxial cell fate specification, vegetative phase change, flower development, ovule development, and response to auxin. It localizes to the nucleus and plant-type cell wall. Associations include seed coat pattern and colour, branch position, pedicel length, carpel and gynoecium morphology, phyllotaxy, self-incompatibility, anther and floral organ development, meristem identity, ethylene and auxin sensitivity, leaf morphology, root length and morphology, and salt tolerance. Studies of related genes in other species link the ARF3 family to polarity determination, seed coat pigmentation, and gametophyte development.
