Inhibition of grana formation by lincomycin.
The antibiotic lincomycin is a specific inhibitor of chloroplast ribosomal activity in greening leaves of Pisum sativum at 1 μg/ml, and prevents both the formation of chloroplast membranes and their stacking into grana. This finding suggests that one function of chloroplast ribosomes is to synthesise at least one protein component of thylakoid membranes.
