YFP::catalase and DsRed2::catalase label peroxisomes. A) Transient expression of YFP::catalase (yellow) in onion cells 24 h after bombardment. Maximum projection (cell depth = 92 μm) of 50 z-stack series. B) Transient expression of YFP::catalase (yellow) in tobacco leaves 48 h after Agrobacterium infiltration. Autofluorescence of chloroplasts is pseudo-colored in red. C) Transient expression of DsRed2::catalase (red) in tobacco leaves 48 h after Agrobacterium infiltration. Autofluorescence of chloroplasts is pseudo-colored in blue.
