ETT — Medicago truncatula

Summary

MTR_2G014770, designated MtETT (also known as ARF3, ARF16, ARF15, ARF2, and MtARF2, MtARF3, MtARF16) on barrel medic chromosome 2, encodes an auxin response factor containing a B3 DNA-binding domain and an ARF domain. The product is annotated as a DNA-binding transcription factor with chromatin binding, protein heterodimerization and homodimerization activities, and transcription cis-regulatory region binding. MtETT is associated with auxin signaling and metabolism, nodulation, root and lateral root development, organogenesis, flower development, fruit ripening, integument and ovule development, abaxial cell fate specification, vegetative phase change, and geotropism. The gene is linked to numerous traits including leaf shape, root length, branch position, phyllotaxy, seed coat pattern and color, carpel and anther morphology, pedicel length, meristem identity, and auxin sensitivity. The protein localizes to the nucleus and plant-type cell wall.
