LOW-TEMPERATURE INDUCED CHANGES IN CHLOROPLAST ULTRASTRUCTURE IN RELATION TO CHANGES IN THE HILL REACTION ACTIVITY, MANGANESE AND FREE FATTY ACID LEVELS IN CHLOROPLASTS OF CHILL-SENSITIVE AND CHILL-RESISTANT PLANTS.

Summary

THE SUBCOOLING OF THE LEAVES OF CHILL-SENSITIVE PLANTS CAUSES AN INCREASE IN THE LEVEL OF CHLOROPLAST FREE FATTY ACIDS, THE FREEING OF ABOUT 60% MANGANESE FROM CHLOROPLAST MEMBRANES AND A DECREASE IN THE HILL REACTION. THE SUBCOOLING OF CHILL-RESISTANT PLANTS HAS NO EFFECT EITHER ON FREE FATTY ACIDS, OR CHLOROPLAST MANGANESE CONTENT OR THE ACTIVITY OF THE HILL REACTION. SUN EXPOSURE, AT AMBIENT TEMPERATURE, OF PREVIOUSLY SUBCOOLED TOMATO LEAVES RESTORES CHLOROPLAST ULTRASTRUCTURE, FREE FATTY ACID AND MANGANESE LEVELS AND THE ACTIVITY OF THE HILL REACTION.
