Freeze-thaw treatment of photosystem 2 (PS2) enriched subchloroplast membranes induced changes in the relative proportion and antenna sizes of PS2α and PS2β. The addition of disaccharides (trehalose or saccharose) and glycine betaine before subjecting to freezing prevented these changes.

Additional key words: cryoprotection; disaccharides; freeze-thaw treatment; photosystem 2 heterogeneity; Pisum sativum; saccharose; subchloroplast membranes; trehalose
