- Abstract
The effects of berberine on the expression of six key photosynthesis-related genes in M. aeruginosa was examined. Berberine induced the expression of psaA and psaB at 1 mg⋅L-1, psbA at 2 mg⋅L-1, but repressed at higher concentrations. It inhibited the transcription of psbD1, rbcL and rbcX significantly (p <0.05). This inhibition of transcription of key photosynthesis-related genes by berberine led to disturbed photosynthesis, specially by blocking the electron transport chain, affecting carbon assimilation and photo-respiratory carbon oxidation.
