ARF2 — Solanum lycopersicum

Summary

SOLYC03G118290.3, designated ARF2 (also known as SlARF2a, SlORE14) on tomato chromosome 3, encodes a protein with ARF, AUX/IAA, PB1, and B3 DNA-binding domains, annotated with transcription corepressor, protein kinase, and sequence-specific DNA-binding activities. The gene is associated with climacteric fruit ripening, lycopene and carotenoid metabolism, pigment accumulation, chlorophyll metabolism, starch anabolism, auxin metabolism, nitrogen utilization, and floral organ morphogenesis. It has been linked to flower organ senescence, axillary shoot formation, fruit set, fruit firmness, fruit weight and size, seed mass, organ size, leaf and root growth, drought tolerance, potassium deficiency tolerance, and susceptibility to Fusarium oxysporum and resistance to Sclerotinia sclerotiorum. Related genes in other species are associated with leaf longevity, flavonol accumulation, and developmental senescence.
