JAS1 — Arabidopsis thaliana

Summary

AT5G13220 (JAS1, also known as JAZ10 or TIFY9) in Arabidopsis thaliana encodes a member of the TIFY/JAZ protein family with molecular functions including bHLH transcription factor binding, ubiquitin ligase substrate adaptor activity, calcium ion binding, and protein homodimerization activity. The gene is associated with the regulation of defense responses to insects, systemic acquired resistance, secondary growth, leaf morphogenesis, and responses to cold and desiccation. It has been linked to numerous agronomically relevant traits including seed protein content, submergence tolerance, shoot elongation under submergence, branch angle, potassium content and sensitivity, calcium concentration, root number, carpel number, silique morphology, stamen development, plant male sterility, and responses to aphids, viral disease, and rice thrips damage. The protein localizes to the nucleus, cytosol, plasma membrane, and plant-type cell wall.
