PRR7 (AT5G02810) — Arabidopsis thaliana

Summary

AT5G02810 (PRR7) in Arabidopsis thaliana encodes a pseudo-response regulator protein containing CONSTANS-like, ARR-like, CCT and CheY-like receiver domains, with annotated molecular functions including phosphorelay response regulator activity, sequence-specific DNA binding, protein kinase activity, and red/far-red light photoreceptor activity. PRR7 is associated with circadian rhythm regulation, rhythmic processes, thermomorphogenesis, TOR signaling, and the regulation of photosynthesis and anthocyanin metabolism. The protein localizes to the nucleus, cytosol, mitochondria, and nuclear bodies. PRR7 has been connected to numerous agronomic traits including grain yield, leaf area index, drought recovery, photoperiod sensitivity, nitrogen content, chlorophyll content, seedling height, vegetative vigor, and heterosis. Related genes in other species link the family to circadian clock function, light sensitivity, stomatal conductance, and oxidative stress response.
