COR15 — Arabidopsis thaliana

Summary

AT2G42540, also known as COR15 or COR15A, encodes a protein in Arabidopsis thaliana that localizes to the chloroplast envelope and stroma. The gene product is associated with multiple binding activities including galactose, chitosan, lipid, and chitin binding, as well as protein kinase activity and ATP binding. COR15A is directly linked to freezing and chilling tolerance, salt stress tolerance, and cold regulation in this species. It is associated with plastid inner membrane organization, sterol homeostasis, regulation of seed development, abscisic acid biosynthesis, drought recovery, and chlorophyll metabolism. The gene is also associated with traits such as freezing stress response, bacterial blight disease resistance, germination rate, root length, chlorophyll content, and transpiration rate. Related genes in other species link the family to chitin signaling, fungal and bacterial disease resistance, and pathogen-induced cell death.
