Effect of Hormones on Changes in Polyribosomal Distribution

Abstract

The influence of some hormones on polyribosome level in pea apicotyl was studied. Profiles polyribosomes were obtained from etiolated stem segments of Pisum sativum L. var. Alaska. In terms of polyrihosome metabolism, expanding tissues yielded large increases in polyri- bosoAies on both a begmenl and fresh weight hasis. Elongating tissues yielded more polyriboso- mes per segment, but only maintained tbem on a fresh weight basis,.Non growing tissue yielded fewer polysomes per segment or per unit fresh weight. These results were found whether the hor­ mones were applied immediatcly after decepitation or after 1 day delay. In this paper, the main purpose is to study the effect of hormones on the level of polyTİbo- somes in pea epicotyl and to relate this Information to what is known about hormones effect on protein.
