Distribution of marker compounds and marker enzyme activities in subcellular fractions of rosemary leaves

Marker	Chloroplast	Endoplasmic Reticulum	Golgi Apparatus	Plasma Membrane
Chlorophylla	185.2 ± 1.0 (100)	0  (0)	0  (0)	0  (0)
NADPH-Cyt c reductaseb	ND c (0)	38.9 ± 0.7 (100)	11.5 ± 1.0 (30)	7.5 ± 2.8 (19)
Latent IDPased	1.8 ± 0.4 (<1)	ND (0)	153.9 ± 5.7 (100)	33.8 ± 5.6 (22)
Vanadate-sensitive ATPased	ND (0)	ND (0)	1.4 (<1)	295.8 ± 60.6 (100)
Cyt c oxidased	2.6 ± 0.65	2.2 ± 0.2	0.7 ± 0.5	0.8 ± 0.1

Data are shown in absolute values and as a percentage of the maximum for each marker (in brackets). Results correspond to the mean ± se of triplicate experiments.
