LOV2 — Arabidopsis thaliana

Summary

AT3G45780 (LOV2, also known as NPH1 or PHOT1) in Arabidopsis thaliana encodes a protein with protein serine/threonine kinase activity, FMN binding, and additional annotated functions including phospholipase activator activity, ubiquitin ligase substrate adaptor activity, blue light photoreceptor activity, and transcriptional co-regulator activity. The gene is associated with phototropic responses, chloroplast accumulation and relocation, stomatal aperture opening, guard cell anion channel regulation, and petiole positioning. It is linked to lateral root growth, leaf angle, leaf positioning, leaf flattening, biomass yield, seed weight, flowering time, auxin content, nitrate transport and uptake, bacterial and viral disease responses, cellulose content, quantum yield, and the xanthophyll cycle. The product localizes to the plasma membrane, cell cortex, vesicles, nuclear bodies, Golgi, vacuole, and plasmodesmata. Studies of related genes in other species link the family to susceptibility to Pseudomonas strains.
