ARF10 — Brassica juncea

Summary

BJUB06G41960S (BjARF10) on chromosome B06 of Indian mustard encodes a protein with ARF, B3 DNA-binding, and PB1-like domains, and is annotated with DNA binding and transcription factor activity. The gene is associated with auxin and ABA signaling, and with numerous developmental processes including embryo, leaf, sepal, petal, pollen, fruit, lateral root, and seed development, as well as vegetative phase change, callus formation, cell division, and pattern specification. It is linked to traits such as seed weight, flowering time, lateral root length, root thickness, petiole length, leaf morphology, osmotic response sensitivity, auxin sensitivity, and biotic stress tolerance. The encoded protein localises to the nucleus and participates in auxin signalling pathways and regulation of seed size. Studies of related genes in other species link the family to root cap and columella cell differentiation, root growth, seed germination, ABA sensitivity, heat tolerance, and male and female gametophyte development.
