ARF6 — Cicer arietinum

Summary

ARF6 (also known as BIP) on chickpea chromosome 1 encodes a protein with DNA-binding and protein-binding activities, belonging to the ARF and AUX/IAA domain families. It is associated with the regulation of seed dormancy and germination, leaf senescence, lateral root development, callus formation, filament development, meiotic cytokinesis, and responses to far-red light, hyperosmotic salinity, and reactive oxygen species. The gene is linked to numerous agronomic traits including adventitious and lateral root number, phototropism, stem elongation, flower and anther development, plant male sterility, gibberellin and cytokinin sensitivity, anthocyanin content, and vegetative-to-reproductive phase transition. It localizes to the nucleus, cytoplasm, cytosol, plasma membrane, vesicles, and cell cortex, and is associated with auxin signaling pathways, notably ARF inactivation by AUX/IAA and proteasomal degradation of IAA13.
