AT5G61380 — Arabidopsis thaliana

Summary

AT5G61380, also known as TOC1 or PRR1, encodes the pseudo-response regulator 1 in Arabidopsis thaliana. This protein possesses DNA-binding transcription factor activity, phosphorelay response regulator activity, and blue light photoreceptor activity, and it localises to the nucleus. TOC1 is associated with circadian behaviour, rhythmic processes, phototransduction, and the regulation of photosynthesis. The gene is linked to numerous traits including petiole size, leaf area, seedling height and vigour, drought recovery, abscisic acid concentration, and far-red light sensitivity. It is also connected to phenotypes such as circadian rhythm, stomatal aperture, drought stress tolerance, and shade response. Studies of related genes in other species link the family to seed set.
