ART1 — Oryza sativa Indica Group

Summary

BGIOSGA013905 (ART1, also known as OiSTOP2 or OiBHLH033) on chromosome 3 of Indica rice encodes a C2H2-type zinc-finger transcription factor belonging to the STOP1/2 family, with sequence-specific DNA binding and transcription regulator activity. The gene is associated with responses to aluminum, acidic pH, hypoxia, hydrogen peroxide, and salinity, as well as with citrate secretion, detoxification, chlorophyll fluorescence, and the regulation of flowering time. ART1 is linked to numerous traits including aluminum resistance, acid soil tolerance, root growth and cell elongation, drought tolerance, salt tolerance, potassium and phosphate homeostasis, and stomatal resistance. The protein localizes to the nucleus. Related genes in other species are linked to aluminum tolerance, phosphorus efficiency, root development under phosphate starvation, malate secretion, and proton stress resistance.
