ART1 — Oryza sativa Indica Group

Summary

BGIOSGA026480 (ART1, also known as OiSTOP1 or OiBHLH033) on chromosome 8 of Indica rice encodes a C2H2-type zinc-finger transcription regulator with sequence-specific DNA-binding activity, localised to the nucleus. ART1 is associated with responses to aluminum, acidic pH, hypoxia, hydrogen peroxide, salinity, and short- and long-day flowering, as well as with citrate secretion, detoxification, chlorophyll fluorescence, and the regulation of vegetative-to-reproductive phase transition. The gene is linked to aluminum resistance, acid soil tolerance, proton rhizotoxicity tolerance, drought tolerance, salt tolerance, low-oxygen tolerance, phosphate starvation response, and root growth traits including primary and lateral root elongation. Related genes in other species are linked to aluminum tolerance, phosphorus efficiency, malate secretion, and proton stress resistance.
