ART1 — Oryza sativa Indica Group

Summary

BGIOSGA037065 (ART1, also known as OiSTOP1 or OiBHLH033) on chromosome 12 of Indica rice encodes a C2H2-type zinc-finger transcription regulator with sequence-specific DNA binding activity. ART1 is associated with aluminum resistance, acid soil tolerance, and proton rhizotoxicity tolerance, as well as with root growth, cell elongation, and lateral root development. The gene is associated with citrate secretion, detoxification, cellular responses to oxygen levels and hypoxia, and regulation of the vegetative-to-reproductive phase transition. Associations also include chlorophyll content, stomatal resistance, and responses to hydrogen peroxide, salinity, phosphate starvation, drought, and low oxygen. The product localizes to the nucleus. Studies of related genes in other species link the family to aluminum tolerance, phosphorus efficiency, and malate secretion.
