Fig. 6. Peroxisomal vesicles compartmentalize proteins.
a Cross-section of 4-day-old cotyledon epidermal cell expressing mNeonGreen-mPTSPEX26 (green) and mRuby3-PTS1 (magenta) shows peroxisomal ILVs enclosing (yellow arrowhead) or lacking (blue arrowheads) PTS1 reporter. b, c Cross-sections of 4-day-old cotyledon epidermal cells expressing mRuby3-PTS1 (magenta), mTagBFP2-SCO3 (blue), and mNeonGreen-mPTSPEX22 (green) (b) or mPTSPEX26-mNeonGreen (green) (c) show SCO3 accumulation (arrowheads) in a subset of ILVs. d, e Cross-sections of 4-day-old cotyledon epidermal cells expressing mRuby3-PTS1 (magenta), mTagBFP2-UP9 (blue), and mNeonGreen-mPTSPEX22 (green) (d) or mPTSPEX26-mNeonGreen (green) (e) show UP9 accumulation (arrowheads) in a subset of ILVs. f Cross-section of 3-day-old cotyledon epidermal cells expressing mNeonGreen-mPTSPEX26 and mRuby3-PTS1 (magenta) shows ILVs with (green) and without (arrowheads) mNeonGreen-mPTSPEX26 membrane fluorescence.
