摘要

We constructed the fusion of peroxisomal acyl-CoA oxidase 3 and the enhanced yellow fluorescent protein (EYFP) for fluorescent labeling of Yarrowia lipolytica peroxisomes. Using the spectral overlap between EYFP and FM4-64, we developed a procedure for simultaneous observation of Y. lipolytica peroxisomes and vacuoles with the single fluorescein isothiocyanate filter set. Using this procedure we were able to follow the Y. lipolytica peroxisome-vacuole dynamics under pexophagy conditions and show that Y. lipolytica peroxisomes are degraded in the vacuoles by a macropexophagic mechanism.
