MtEPP1 localizes at the cytoplasm. (A–C) The eGFP fluorescence in M. truncatula root cells expressing the control vector (35S::eGFP). (D–F) The cytoplasmic localization of the MtEPP1::eGFP fusion under control of the 35S promoter in M. truncatula root cells. Scale bars represent 10 μm. Pictures shown are representative of three biological replicates, each one containing five transgenic roots.
