ARF3 — Medicago truncatula

Summary

MTR_2G018690 (MtARF3) encodes an auxin response factor (ARF) family transcription factor, possessing B3 DNA-binding, AUX/IAA, and PB1-like domains, and is annotated with DNA binding and transcription factor activity. In barrel medic, MtARF3 is associated with the regulation of auxin biosynthesis and signaling, lateral root morphogenesis, seed dormancy, leaf senescence, thermomorphogenesis, and filament development. It localises to the nucleus and cytoplasm. The gene is linked to numerous agronomic traits including fruit quality, total soluble sugar content, carotenoid content, plant male sterility, adventitious root number, lateral root number, shoot axis branching, heterosis, and temperature stress response. Related genes in other species are linked to drought tolerance, thermomorphogenesis, phototropism, and nutrient response, as well as ascorbic acid and soluble solid content.
