Subcellular localization of ZmCATs in maize cells. a Maize protoplasts were transfected with each plasmid as indicated on the left of each column. DsRed-SKL was used as a peroxisome marker. Red fluorescence signal was captured at 24 hpt. Bars, 10 μm. b Maize leaves were co-bombarded with GFP-ZmCAT1/2/3 and DsRed-SKL and the bombarded leaves were examined for the expression of fusion proteins at 36 hpb. Bars, 10 μm
