Mutant chloroplasts in variegated cotton leaves contained reduced amounts of pigments, were smaller, and lacked any well defined grana system when compared with normal green chloroplasts. Replication of the defective chloroplasts was not altered. Mutant leaves fixed reduced amounts of 14 CO 2 by photosynthesis, and the white leaves had a shift in the distribution of the products of 14 CO 2 fixation. Mutant leaves utilized 14 C‐2‐acetate as effectively as green leaves.
