ARF9 — Cicer arietinum

Summary

CaARF9 (LOC101515039) on chickpea chromosome 6 encodes a protein with ARF, AUX/IAA, PB1-like, and B3 DNA-binding domains. It has DNA binding transcription factor activity, transcription corepressor activity, and binds DNA, proteins, and cis-regulatory regions. It localises to the nucleus and cytoplasm. CaARF9 is associated with meristem development, shoot apical meristem development, leaf vascular tissue pattern formation, lateral root morphogenesis, abaxial cell fate specification, filament development, vegetative phase change, flower development, fruit ripening, gibberellic acid homeostasis, and positive regulation of leaf senescence. It is linked to yield, biotic stress tolerance, osmotic response sensitivity, auxin and brassinosteroid sensitivity, and traits including leaf number, phyllotaxy, adventitious and lateral root number, stomatal process, leaf vein and vascular morphology, and sulfur content. Related genes in other species are associated with lateral root organogenesis, vascular tissue development, shoot regeneration, and auxin accumulation.
