MGDG contains a minor amount of monoglucosyldiacylglycerol. The values are the averages from two independent experiments.
Thylakoid membranes were isolated from the cells grown in the presence of 20 μm PG.
Cells grown in the presence of PG were transferred to medium without PG, incubated for 5 d, and then thylakoid membranes were isolated.
