Carboxydismutase activity in plants with and without β-carboxylation photosynthesis.

abstract：:Cycloheximide (CH) was applied selectively either to the shoot apex or by infiltration to the leaves of the long-day plant Hyoscyamus niger in order to investigate whether this inhibitor has an effect on the synthesis of a floral stimulus in the leaves. Treatment of the shoot apex with CH caused inhibition of the phot...
