Pex14-containing vesicular structures mature into peroxisomes upon reintroduction of PEX3. (A) FM images of pex3 cells with Pex14-mCherry upon Pex3-eGFP reintroduction after shifting cells from MM-Glu with ammonium sulfate to MM-M/G with methylamine. (B–E) Live cell FM images of pex3 atg1 cells upon Pex3 reintroduction. Shown are pex3 atg1 cells producing Pex14-mCherry and PAMOPEX3-eGFP (B), PAMOPEX3.PEX10-GFP (C), PAMOPEX3.PMP47-GFP (D), or PAMOPEX3.PTEFGFP-SKL (E). Cells were grown similar to the method in A. The arrows in B–D indicate the first detectable GFP signal. Bars, 2.5 µm.
