MGP — Cicer arietinum

Summary

LOC101496559 (CaMGP, also known as CaIDD8, CaNUC, CaIDD3, MGP, IDD3, NUC, IDD8) on chickpea chromosome 6 encodes a protein with C2H2-type zinc finger domains belonging to the IDD1-16 family. The protein possesses DNA-binding, protein kinase, and phosphatase-binding activities, localizes to the nucleus, cytosol, and Golgi, and is associated with promoter-specific chromatin binding. In chickpea, CaMGP is linked to developmental processes including vegetative phase change, primary root development, asymmetric cell division, regulation of meristem size, seed dormancy, leaf senescence, and meiotic cytokinesis. It is also associated with responses to trehalose, acidic pH, herbicides, aluminum, and short-day flowering, as well as positive regulation of autophagy and upregulation of gibberellic acid-mediated signaling. Associations with agronomic traits include seed yield, days to flowering, vegetative growth time, submergence tolerance, high temperature stress response, anthocyanin content, root hair length, and plant male sterility. Studies of related genes in other species link the family to energy sensing, metabolic regulation, stress tolerance, and circadian clock periodicity.
