CBP60G — Arabidopsis thaliana

Summary

AT5G26920 (CBP60G) on chromosome 5 of Arabidopsis thaliana encodes a calmodulin-binding protein 60 G, a DNA-binding transcription factor with calmodulin-binding domains. The gene is associated with the regulation of salicylic acid biosynthetic and anabolic processes, systemic acquired resistance, and responses to molecules of bacterial origin. CBP60G is linked to disease resistance, immunity, pathogen defense, and resistance to Pseudomonas syringae and powdery mildew. It is also linked to drought tolerance, abscisic acid sensitivity, anthocyanin accumulation, plant biomass, ethylene sensitivity, and photochemical quenching. The encoded protein localizes to the nucleus and is associated with calcium signaling, hormone metabolism including auxin and ethylene, camalexin anabolism, and chlorophyll fluorescence. Studies of related genes in other species link the CBP60 family to bacterial susceptibility and salicylic acid response.
