ARF3 — Solanum lycopersicum

Summary

SlARF3 (SOLYC02G077560.3) on tomato chromosome 2 encodes a member of the auxin response factor family, containing B3 DNA-binding and ARF domains, and functions as a DNA-binding transcription factor with chromatin binding, protein heterodimerization and homodimerization activities. The gene is associated with auxin signalling, lateral root emergence, and the regulation of seed size and development. It is linked to fruit ripening, climacteric fruit abscission, carotenoid and chlorophyll metabolism, palisade mesophyll development, abaxial cell fate specification, floral organ morphogenesis, leaf formation, and responses to flavonoids and nitrogen fixation. Associations also include numerous traits such as fruit size, leaf shape, sugar content, water use efficiency, salt response, ethylene and auxin sensitivity, seed coat pattern and color, flower shape, inflorescence branching, pedicel length, root branching, and stomatal resistance. The protein localizes to the nucleus and plant-type cell wall.
