Analysis of the root protein sample. 20 μg of crude root protein extract (C), the pellet representing root plastids (P) and supernatant representing cytosol (S) were separated by SDS-PAGE, transferred to a PVDF membrane and immunolabelled with root-type FNR (RFNR; root plastid marker), alternative oxidase (AOX1/2; mitochondrial marker) and nitrate reductase (NR; cytosolic marker) antibodies
