Alternates Peroxisomal Contents in Response to Trophic Conditions.

is a model green microalga capable of heterotrophic growth on acetic acid but not fatty acids, despite containing a full complement of genes for β-oxidation. Recent reports indicate that the alga preferentially sequesters, rather than breaks down, lipid acyl chains as a means to rebuild its membranes rapidly. Here, we assemble a list of potential peroxins (PEXs) required for peroxisomal biogenesis to suggest that has a complete set of peroxisome biogenesis factors.
