Abstract

A protocol for the isolation of functional thylakoids from Arabidopsis thaliana leaves was developed. The critical factor in obtaining active, coupled and stable preparation is the inclusion of EDTA and EGTA in the grinding buffer. Preparations were characterized with respect to the whole or partial electron transport chain, ATP/NADPH, ATP/O2 and PS II/chlorophyll ratios. Sensitivity to a light-chill photoinhibitory treatment was also determined by evaluating the decrease in both maximal photochemical efficiency (Fv/Fm) and in electron transport rate.
