Abstract

A comparative study of peptide composition and freeze-fracture morphology of chloroplast membranes from a chlorophyll b-less mutant and a normal barley plant (Hordeum vulgare L.) is reported in this work. Using a high resolution, discontinuous sodium dodecyl sulfate—acrylamide gel electrophoretic system, we show that the mutant chloroplast membranes not only completely lack the 25-kilodalton peak, which accounts for about 18% of the chloroplast membrane protein in the normal plant, but also exhibit gross reduction in other components at 27.5- and 20-kilodalton regions. Despite such extensive deletions in the peptide composition of the mutant chloroplast lamellae, no alteration could be detected in either density or size of the intramembranous particles, visualized by freeze-fracturing.
