In one of our earlier papers (Wu et al. 1978), we suggested that glutelin is the major composition of the round storage protein bodies although they also contain relatively more prolamine than the angular one does. Immunochemical studies of Krishnan et al. (1986) later showed the presence of glutelin in the irregularly-shaped (angular) protein bodies while the prolamines were found in the round ones. Our recent experiment using protein A-gold technique found that prolamine is mainly deposited into the angular protein bodies.Small blocks (1 mm3) of 7 DAF (days after flowering) caryopsis of Orvza perennis were fixed with 3% paraformaldehyde and 3% glutaraldehyde in 0.1M sodium phosphate, pH7.4, dehydrated in a graded ethanol series and infiltrated with Spurr’s resin. Thin sections, after gold labeling, were stained with uranyl acetate and lead citrate. Rabbit antibodies were raised against purified prolamine. Protein A-gold sol complex was prepared based on the technique of Horisberger et al. (1977).
