EIF — Solanum tuberosum

Summary

StEIF (PGSC0003DMG401017153) on potato chromosome 9 encodes an mRNA cap-binding protein that is a subunit of the eIF-(iso)4F complex, with RNA m7G cap binding, translation initiation factor activity, and RNA binding functions. The gene is associated with defense response, regulation of antiviral response, response to virus, virus-induced PTGS, and downregulation of antiviral response. It is linked to disease tolerance, virus resistance, and susceptibility to Pepper veinal mottle virus, Turnip mosaic virus, and potexvirus infection. Additional associations include root hair length, root morphology, regeneration, protein synthesis, translation regulation, and localization to the cytoplasm, nucleus, and plastid. Studies of related genes in other species link the family to potexvirus susceptibility, Turnip mosaic virus resistance, cold acclimation, and root development.
