NR activities in wild-type (WT) and
transgenic N. plumbaginifolia plants ectopically
expressing NR. Plants were grown in the greenhouse and harvested at the
beginning of the light period. Results are from two independent
experiments. C1 and del8, Transgenic plants expressing, respectively, a
wild-type NR protein (35S-NR) and the ΔNR protein (35S-ΔNR). A1 and
A2, Transgenic plants expressing the ΔA-NR protein. S2, S4, and S9,
Transgenic plants expressing the ΔS-NR protein.
