MpSMXL is subject to proteosome-dependent degradation. A–C, Subcellular localization of MpSMXL–Citrine in N. benthamiana epidermal cells treated with 0.25% (v/v) DMSO (A), or 100-μM MG-132 (B). Subcellular localization of MpSMXL^d53–Citrine in N. benthamiana epidermal cells (C). Micrographs showing cells expressing MpSMXL–Citrine or MpSMXL^d53–Citrine were examined under fluorescence (left), bright field by confocal microscopy. Merged (middle) and enlarged (right) images are shown for each analysis. Bar = 50 μm.
