SR1 — Arabidopsis thaliana

Summary

AT2G22300 (SR1, also known as CAMTA3) encodes a protein containing CG-1, ankyrin repeat, IQ motif and Ig-like domains. It is a sequence-specific DNA-binding transcription factor that binds calmodulin and cis-regulatory regions. In Arabidopsis, SR1 is associated with cold tolerance, cold stress tolerance, cold acclimation, cellular response to cold, and stomatal closure. It is linked to salicylic acid anabolism, systemic acquired resistance, response to herbivore, upregulation of defense response to insect, calcium signaling, extracellular ATP signaling, glucosinolate metabolism, and the MEP pathway. The gene is also associated with cellular response to aluminum, nuclear export, and nonsense-mediated mRNA decay. Associations with traits include seed size, flowering time, leaf senescence, root development, anthocyanin and carotenoid content, and responses to high temperature, submergence, and salt stress.
