ARF10 — Solanum lycopersicum

Summary

SlARF10 (SOLYC11G069500.2) encodes an auxin response factor (ARF) family transcription factor on tomato chromosome 11, containing B3 DNA-binding, ARF, and PB1 domains, with DNA-binding and miRNA-binding activities. In tomato, SlARF10 is associated with fruit development and shape, ovary patterning, leaflet and leaf blade development, root branching, chlorophyll accumulation, photosynthesis, and leaf water loss. The gene is linked to auxin signalling, ARF inactivation by AUX/IAA, seed development, and regulation of seed size, as well as processes including carpel formation, sex differentiation, fruit and leaf abscission, abaxial cell fate specification, and cytokinin biosynthesis. Associations extend to fruit weight, sugar content, biomass yield, plant height, flowering time, root length and number, stomatal resistance, and biotic and osmotic stress responses. Studies of related genes in other species link the family to root meristem development, gametophyte development, disease resistance, and high-temperature stress response.
