ARF1 — Triticum aestivum

Summary

TRAESCS3B02G190100, designated TaARF15 (also known as ARF1, ARF16, TaARF16, and TaARF21) on bread wheat chromosome 3B, encodes a protein containing ARF, AUX/IAA, PB1-like, and B3 DNA-binding domains. The protein exhibits DNA binding, transcription cis-regulatory region binding, and protein heterodimerization and homodimerization activities. TaARF15 is associated with auxin signaling and response, anther development, leaf senescence, climacteric fruit ripening, flower development, cell cycle, DNA metabolism, and epigenetic regulation of gene expression. It localizes to the nucleus. The gene is linked to male sterility in wheat and to numerous agronomically important traits including grain yield, seed size, plant height, tiller number, root dry weight, drought and salinity tolerance, stripe rust disease response, photosynthetic rate, chlorophyll and protein content, and potassium uptake.
