Effect of gibberellic acid on photosynthesis and glycollate dehydrogenase in Anacystis nidulans

Gibberellic acid at 10(-4) MXXX was optimal for enhancement of growth, O2 evolution, photosystem II and I and the activity of glycollate dehydrogenase of Anacystis nidulans. A stimulatory effect was observed on photosystem II. Other concentrations of gibberellic acid were inhibitory to O2 evolution...

Description
Summary:Gibberellic acid at 10(-4) MXXX was optimal for enhancement of growth, O2 evolution, photosystem II and I and the activity of glycollate dehydrogenase of Anacystis nidulans. A stimulatory effect was observed on photosystem II. Other concentrations of gibberellic acid were inhibitory to O2 evolution and photosystem I. Syntheses of phycocyanin, phycoerythrin and β-carotene were significantly enhanced after 48 h incubation with gibberellic acid at 10(-3) MXXX but the chlorophyll content began to increase 3 h after adding 10(-4) MXXX gibberellic acid.
