ADO3 — Arabidopsis thaliana

Summary

AT1G68050 (ADO3/FKF1) in Arabidopsis thaliana encodes a protein with DNA-binding transcription repressor activity, RNA polymerase II-specific, glutamine synthetase activity, photoreceptor activity, and blue light photoreceptor activity. The protein contains F-box, PAS, PAC, and Kelch-repeat domains. FKF1 is associated with photoperiodism, circadian clock photoentrainment, rhythmic processes, and temperature compensation of the circadian clock. It is linked to upregulation of long-day photoperiodism, flowering, organ growth, circumnutation, and negative regulation of cellulose anabolism. The gene is associated with numerous agronomic traits including harvest index, stem number, leaf area index, plant dry weight, seedling vigor, drought recovery and sensitivity, photoperiod sensitivity, inflorescence height, fruit set, and leaf temperature. FKF1 localizes to the SCF ubiquitin ligase complex, thylakoid, and mitochondrial outer membrane, and is associated with protein polyubiquitination and proteasomal protein catabolic process.
