Changes in chloroplastic and cytoplasmic ribosomal protein after GA3-treatment of Zea mays leaves

Abstract


Protein was isolated from chioroplastic and cytoplasmic ribosomes of 14-day-old maize leaves subjected to the action of gibberellic acid. The proteins were separated electrophoretically on polyacrylamide gel. Fourteen fractions of ribosomal protein were obtained exhibiting wide electrophoretic differences. Qualitative differences were found between the chloroplastic and cytoplasmic ribosomes. Gibberellic acid caused the appearance of an additional protein Traction in cytoplasmic ribosomes. It did not, however, affect the qualitative composition of ribosome proteins from chloroplasts.
