ART1 — Sorghum bicolor

Summary

SbART1 (SORBI_3001G020200) on sorghum chromosome 1 encodes a C2H2-type zinc finger protein with transcription regulator activity, sequence-specific DNA binding, and DNA binding transcription factor activity, localised to the nucleus. The gene is associated with citrate secretion, responses to aluminium, acidic pH, hypoxia, hydrogen peroxide, salinity, and both short-day and long-day flowering, as well as the regulation of vegetative-to-reproductive phase transition. It has been linked to aluminium resistance, acid soil tolerance, drought tolerance, salt tolerance, low-oxygen tolerance, phosphate starvation response, potassium ion homeostasis, root and plant growth, and proton rhizotoxicity tolerance. Studies of related genes in other species connect the family to aluminium tolerance, phosphorus efficiency, root development under phosphate starvation, malate secretion, and proton stress resistance.
