GPPS and GGPPS Activities in the Isolated Chloroplasts from Control and Transgenic Leaves

Activity	Control	GPPS.SSU-1	GPPS.SSU-3	GPPS.SSU-7
GPPS	0.21 ± 0.12	1.41 ± 0.13**	0.40 ± 0.03*	1.75 ± 0.18**
GGPPS	0.42 ± 0.08	0.23 ± 0.06**	0.28 ± 0.08*	0.12 ± 0.01**

Values are pkat/mg protein (means ± se, n = 3). Confidence levels were tested by a Student's t test; *, P < 0.01; **, P < 0.003.
