PTS1-Dependent Protein Import in Pollen Grains from the Wild Type and pex Heterozygous Mutants.
(A) mCherry-PTS1 displayed punctate peroxisomal localization in wild-type pollen.
(B) to (D) mCherry-PTS1 displayed a diffuse pattern in pex10
(B), pex12
(C), and pex13
(D) pollen (white arrows).
(E) Peroxisomal localization of mCherry-PTS1 in pex14 pollen.
(F) Aggregated and reduced mCherry-PTS1 localization in pex16 pollen (white arrows).
